A widget is a software application embedded in the Equinox device that controls and communicates with the equipment for that widget. Widgets allow for intuitive system navigation and control by users. They also provide the power for personalization, allowing users to adapt the system to their changing living environment. Equinox widgets are the very efficient means that allow integrators to program intuitive control for complex requirements.

With the shade widget, gain complete control and visibility of all automated window shading systems on the project. On the shade widget dashboard, users can quickly see which shades are open or closed and adjust the position of the current shade group. There are also up to four presets available that can be activated from this main screen. Define presets on the second or “full screen level.” These presets are shared across all profiles and are tied directly to the shade group. Edit any shade preset level on Equinox 73 or a mobile tablet.

At the full screen level, there are two view types. By default, users will see and be able to manage the individual shades of the current group. Then, swipe to see the shade overview page where users can see the status of all the shade groups and then open or close the shades in a project.

At the full screen level, there are two view types. By default, users will see and be able to manage the next instance of all scheduled events in a scrollable list. Then swipe to see the timers page for the current profile. This shows daily, weekly, monthly, and other types of timers as well as the time of the day they are scheduled to execute.

At the full screen level, lists of lights by floor and by room can be viewed; swipe side to side to see more floors or up and down to show more rooms. See what lights are on or off, turn individual, room, or floor lights on or off, and raise or lower dimmable lighting loads.

HMI, an acronym meaning Human Machine Interface, is exactly what the name implies. It is simply an interface – usually graphical – that lets humans and machines interact. The precise date of inception for this technology is not known due to the huge graphical interface boom we have had, and are still experiencing. Examples of HMIs vary widely, from control panels for nuclear power plants, to the screen on that new iPhone. More often than not, when a person refers to a Human Machine Interface or HMI, he/she is referring to a control panel for a manufacturing-type process. An HMI in this context is the centralized control unit for manufacturing lines, equipped with Data Recipes, event logging, video feed, and event triggering so that you may access your system at any moment for any purpose. For a manufacturing line to be integrated with a Human Machine Interface, it must first be working with a Programmable Logic Controller (PLC) because the PLC is what takes all the information from the sensors and transforms it to Boolean algebra so the Human Machine Interface can decipher and make decisions.

HMIs offer a digital display of data in real time that a PLC cannot offer. While the PLC is performing its programmed operation, an HMI allows for the user to see data in real time rather than compiling the data to observe after the fact. An example to reference for an HMI with a PLC rather than a PLC standalone would be an ATM Machine. If there was no graphical display, a user would be dependent on receipts to enter in data. That is, imagine inserting your personal ATM card only to have a receipt print out requesting your PIN. Then, once into your account, a receipt prints out asking which action you would like to perform; deposit, withdraw, transfer, or balance inquiry. This issue is solved by a Human Machine Interface through which you can make your selection at a touch of a button. While the HMI is not critical in this scenario, it is much more efficient and user-friendly. Many applications do not require an HMI, but the cost savings associated with the benefits of HMIs are heavily skewed in favor of the HMI being a system component.

The main advantage of a Human Machine Interface (HMI) over a desktop computer is that, with an HMI, there is a dedicated system specific to your application. This means that you have a panel which will not allow internet browsing, solitaire game playing, or update reminders, unless it pertains to your application. HMIs give you absolute control – you may give the operator limited access to specific features or full access, depending on how you create your graphical interfaces.

The software required to program a Human Machine Interface differs from each vendor as well as model. Concerning Kinco product lines, MT4000, MT5000, F7/F10, and SZ series HMIs are all programmable on Kinco HMIWare. The CZ6/CZ10 and Green Series HMIs are programmed on Kinco DTools Software, and the HP043 (HMI-PLC Combo unit) is programmed on Kinco HP Builder Software. Should you need any assistance programming your Kinco HMI with any of these proprietary software products, feel free to Contact an Applications Engineer at Anaheim Automation. Anaheim Automation, Inc. is Kinco"s Master Distributor in North America.

HMI software downloads are available in the Item table shown above on this web page. Please locate your HMI product in the Item column, and download the applicable software by clicking on the disc icon in the Downloads column. Individual product Item pages also contain links for the appropriate software download.

For Ethernet based protocols, the HMIs can support up to 255 distinct nodes. For Serial based protocols, you can hook up as many controllers as the HMI has COM ports. When using RS485 hardware, daisy chaining nodes may be applicable to add unique nodes.

"HMI" is an acronym that stands for Human Machine Interface. A basic definition for an HMI is any interface between a human operator and a machine or system. A lesser used synonym is Man Machine Interface, or MMI. Technically, "Human Machine Interface" is a broad term describing any interface that allows a human to interact with a machine, and can include, for example, devices such as MP3 players, industrial computers, household appliances, and office equipment. However, the terms "HMI" or "Human Machine Interface" are typically used in contexts specific to manufacturing and other industrial processes. A Human Machine Interface provides a visual representation of a process control system with real-time data acquisition. HMIs can increase productivity by providing a centralized control center that can be made extremely user-friendly.

A Human Machine Interface provides a visual representation of a process control system with real-time data acquisition. HMIs can increase productivity by providing a centralized control center that can be made extremely user-friendly.

The convenience that comes with a Human Machine Interface is priceless. You will find that once you have digitized your system, the functionality you will get out of your HMI is unbeatable. An HMI combines all the control features that are found throughout your automation line and places them all in one centralized location; no more having to run to that red pushbutton that will stop your line. With remote access, you don"t have to be anywhere near your automation line to start/stop or monitor production, and you can have all the same features you have on your centralized unit in a smaller compact form. Along with ease of access from wherever you may be, simplicity is also a big factor in the usability of a Human Machine Interface. With simplistic screens and functions you can train almost anyone to supervise your automation line.

The great thing about a Human Machine Interface is that you can personalize your interface however you would like. If you want to develop a complex system with multiple screens and several routines always running, an HMI fully supports that. If you are looking to program a Human Machine Interface with something more simplistic, you could have instructions for the controller directly written onto the interface. Every HMI comes with different features. Some may play sound or video, or even may have remote access control. The design of any particular interface should be optimized for that specific application, taking into account environmental aspects and operators such as noise, lighting, dust, vision and technological curves.

Pushbutton replacer HMI: Before the Human Machine Interface came about, controlling automation lines was no easy task, due to the use of up to thousands of pushbuttons and LEDs all performing different tasks. The pushbutton replacer HMI takes the place of LEDs, on/off buttons, switches, or any mechanical device that has some control over the unit. The integration of PLCs and Human Machine Interface devices has virtually eliminated the use of pushbuttons and LEDs because any function that a pushbutton or a LED could perform can easily be done with an HMI, all in one centralized location. The elimination of these mechanical devices is possible because the Human Machine Interface can provide a visual representation of all these devices on its LCD screen while performing all the same functions.

The Data Handler HMI is used for applications that require constant feedback and monitoring. With the data handler type of Human Machine Interface, it is important that the HMI screen is big enough to display elements such as graphs, system visualizations, and production summaries. This type of Human Machine Interface is capable of functions such as recipes, data trending, data logging, alarm handling/logging, and even printing production reports. Performing these tasks can be very memory intensive, so for the Human Machine Interface to work as a data handler, it will usually need to have a large-capacity memory.

An Overseer Type HMI is advantageous when the application involves OEE, SCADA, or MES, which are centralized systems that monitor and control entire sites or complexes of large systems spread out over large areas. An overseer HMI is usually linked to a central processing unit (CPU) or database and software programs to provide trending, diagnostic data, and management information. These types of applications will likely require an HMI that can run a dynamic operating system (e.g. Linux) and has several Ethernet ports.

In addition to the role the HMI will play within a given system, Environmental Considerations and Physical Properties, such as screen size, should also be taken into account when selecting an HMI. Please refer to those sections below for more information on HMI selection.

The physical properties of an HMI vary from model to model, so it is important to select the right one. For example, an HMI that is located in a water plant might have various water seals around its perimeter, as opposed to a unit that is located in a pharmaceutical warehouse. The size of as HMI is also a key variable, because not all applications need a large, high resolution monitor; some applications may only need a small, black and white touch screen monitor. When it comes to selecting a Human Machine Interface, the physical properties are extremely important because you have to take into consideration the operating environment and what safety measure the Human Machine Interface has to protect itself. Also, a specific size may be needed due to space limitations. Lastly, physical properties include the processor and memory of the Human Machine Interface. It is important to make sure that these two are sufficient enough to control your system.

Sometimes when you are working with HMI software, your PLC and HMI are hooked up together, but you don"t quite get the result you are looking for. It is hard to know exactly what is going on when you do not get output from the PLC or a PLC error appears. What happened? What exactly did I do wrong? Is my data even being sent? To answer all those questions, you can simply use a numeric display and set it to the PLC register you are trying to write your data to. If this PLC register comes back with random register values, then it is quite apparent that the HMI did not deliver the information to that register. But if it was sent correctly, then your numeric displays should show the information you sent. This is a very simple sanity check.

Macro: Macro instructions are an advanced touch screen control method that strengthens the functions of the Human Machine Interface. The Human Machine Interface will have the same logic and arithmetic operations as the PLC by the programming of macros. The use of macros will enable the touch screen to implement many powerful functions that cannot be supported by many regular components.

TFT: TFT stands for "Thin Film Transistor." Kinco HMI displays are TFT LCD screens in which TFT technology supports the rendering of high-quality images.

OctoScreen is a LCD touch interface for your OctoPrint server. It is based on GTK+3 and allows you to control your 3D Printer using a LCD touch screen, a Raspberry Pi, and OctoPrint. It"s an X application that"s executed directly in the X Server without a window manager or browser, and operates as a frontend for OctoPrint.

TouchUI is an amazing plugin for OctoPrint. It was created as a responsive design application to access OctoPrint from low resolution devices, such as smartphones, tablets, etc.

Executing TouchUI under a RPi with a TFT display presents two big problems: First, it isn"t optimized to be used with resistive touch screens with low resolutions like 480x320, and second, it requires a browser to run, which consumes a lot of resources. This is the main reason OctoScreen was developed as an X application.

OctoScreen is based on GoLang. GoLang applications are usually dependency-less, but in this case GTK+3 is used, and the GTK+3 libraries are required in order to run. Be sure that GTK+3 is installed and is the only graphical environment that"s been installed.

You will also need to set up the video drivers for the display you are using. Installation and configuration of the drivers is usually specific to the display you are using, and you will need to contact the manufacturer for instructions. To help you set up your system and display, a setup guide (Setting Up OctoScreen and Your Display) is available in the wiki.

There are two ways to install OctoScreen: the recommended and supported way is to install from a .deb package, or you can choose to install from building the sources yourself. The recommended way to install OctoScreen is use the .deb packages from the Releases page. The packages are available for Debian Stretch based distributions such as Raspbian and OctoPi.

OCTOPRINT_HOST - The URL to the OctoPrint server. Example: http://octopi.local or http://localhost:5000. Note: the protocol (http:// or https://) is required. If the setting for OCTOPRINT_HOST does not contain the protocol, an error will be displayed when OctoScreen starts.

OCTOPRINT_APIKEY - OctoScreen expects an API key to be supplied. The API key can either be set in OctoScreen"s config file, or in OctoPrint"s config file (OCTOPRINT_CONFIG_FILE below)

OCTOSCREEN_STYLE_PATH - Several themes are supported, and style configurations can be done through CSS. This variable defines the location of the application theme.

OCTOPRINT_CONFIG_FILE - The location of OctoPrint"s config.yaml file. If empty, the file path used will be the pi home folder of the current user. The OCTOPRINT_APIKEY is required, and if it isn"t defined in OctoScreen"s config file (see OCTOPRINT_APIKEY above) it needs to be defined in OctoPrint"s config file.

OCTOSCREEN_LOG_FILE_PATH - The file path to where the log file will be saved. The file path should be a fully qualified path and not only include the path to the log file, but the name of the log file as well (eg /home/pi/logs/logfile.txt). The log file is appended to and is never automatically truncated, and will grow over time. If you turn log file logging on (by specifying a path), be sure to turn it off (by setting the value to "").

OCTOSCREEN_LOG_LEVEL - Controls the level of logging. Accepted values are (with increasing levels): debug, info, warn, and error. If no value is provided, the log level will default to warn.

OCTOSCREEN_RESOLUTION - Resolution of the application, and should be configured to the resolution of your screen. Optimal resolution for OctoScreen is no less than 800x480, so if the physical resolution of your screen is 480x320, it"s recommended to set the software resolution 800x533. If you are using Raspbian you can do it by changing hdmi_cvt param in /boot/config.txt file. Please see Setting Up OctoScreen and Your Display and Installing OctoScreen with a 3.5" 480x320 TFT screen for more information.

DISPLAY_CURSOR - To display the cursor, add DISPLAY_CURSOR=true to your config file. In order to display the cursor, you will also need to edit /lib/systemd/system/octoscreen.service and remove -nocursor

Thanks for bringing this to my attention. It appears that the upgrade package overwrites the FBTFT drivers, in particular, the Raspberry Pi bootloader. This seems to solve the problem:

Hello..I tired to interface this lcd “https://www.crazypi.com/raspberry-pi-products/Raspberry-Pi-Accessories/32-TOUCH-DISPLAY-RASPBERRY-PI” to my Raspberry pi model B+.I got a DVD containing image for LCD in the package.I burned it to the SD card and plugged in the display.But my lcd is completly blank.But green inidcation led (ACT LED) in board is blinking.Why my LCD is Blank ?

If you have tried using the manufacturers image and the screen doesn’t work, it could be that the screen has a hardware malfunction. If the process above doesn’t work either, I would contact the manufacturer

Is your RED (POWER) LED on? I had the same problem. Green Led was blinking and screen was white. Then I noticed RED Led is off, indicating there’s something wrong with the power. I plugged into different port and it started

Yes, it may be that the screen isn’t supported. Newer screens might not have drivers yet. I do know it is possible to make your own driver but that’s above my level of knowledge :)

My Touchscreen is now working fine.The problem was for the ribbon cable on the back side of LCD.It was not connected properly.I just tighted the cable and it worked fine.Hope it will be useful tip.

Thank you for this great tutorial. I looked everywhere for this information. I have an eleduino 3.5 version A. I was able to get it working on my Pi 2 by following your tutorial and using flexfb as the screen type. I got the other settings from the image that came with the product. I did find that the ts_calibrate didn’t recognize the screen so I installed xinput-calibrator and it worked fine.

Just got my Pi2 running Wheezy, working with the Eleduino 3.5 LCD without running the OEMs image… kinda. I didn’t want to rebuild the application environment again, so was avoiding flashing the SD.

I tried the steps in this tutorial. It’s very clear and easy to follow, thank you. But it didn’t work for me, I tried setting my device to flexfb. Only got white screen.

thank you for your great tutorial, it got me on the right way. unfortunataly i only see some boot messages on the lcd and then it turns black. maybe you could give me a hint on how to get it working entirely.

Did you check to see if your device is supported yet? The device name should be specific for your screen, as listed in the fbtft file linked to in the beginning of the post

I too have a raspberry pi 2, and a waveshare spotpear 3.2 RPi lcd (v3) and I just can’t get it to work! I suspect I have a faulty LCD, but thought I’ll try this forum for help before I sent it back.

Soon as the pi is powered, the LCD lights up all white, with a few vertical pixels coloured at one of the edges, and nothing else. I don’t think that should happen – not at least before the BOIS has started up.

Anyway, point 1, says to change to dev/fb1 – I don’t have fb1. Only fb0 appears to be there. is that a clue what could be wrong? I have enabled SPI (is there a command to tell if its enabled?) I have also ran spidev to troubleshot (though I haven’t a clue what I means)

It seems all appears to be working – just the LCD is still all white with a single line of coloured pixels on edge) and nothing else. Is there a way to output, like jeff G script, of touch points?

I had the same one, I finally found a driver for it here: http://www.waveshare.net/wiki/3.2inch_RPi_LCD_(B) you will need to translate the page, but unpack the driver then run sudo ./LCD-show/LCD32-show. It should reboot and all will be good with the screen :)

Can anyone let me know if the default OS image sent with the screen works with pi2 or just Pi B/B+ as i think my screen maybe broken but can’t confirm it yet as i have not had it working at all

My system: Raspberry Pi 2 Model B with Raspian Wheezy from Febuary 2015. LCD display of Sainsmart 3.2 http://www.conrad.de/ce/de/product/1283498/Raspberry-Pi-Display-Modul-Touch-Display-81-cm-32/?ref=home&rt=home&rb=1

The LCD display shows the raspberry correctly. However, the touch screen input does not work. The mouse pointer can I move correctly with your finger, but I can not select things (function of the left mouse button).

Can someone upload SD card image that works with RBP2 ? My idea is to use Eleduino TFT as additional screen and play movies via HDMI.. is it possible?

Do not follow this article when you don’t know what kind of LCD module. In my case, I follow all of this and my raspberry pi cannot boot anymore. I will try to recover, but I think I should format my SD card and reinstall OS.

Expecting this would builtin driver module within kernel and help with avoiding mistakenly overwriting anything. But with this is cause LCD screen to go blank white and no boot activity. Also noticed on HDMI it get stuck on Initial rainbow screen and stuck on that.

Also can you someone explain what exactly happen when do rpi-update? Want to understand what this step actualy doing and help me to debug any such situation and able to help others.

Does anyone tried splash boot screen with waveshare v4 LCD and Rpi2? I tried to follow some example from https://github.com/notro/fbtft/wiki/Bootsplash but no success.

Great tutorial thanks; got an X session working great 1st time. Has anybody managed to get Kodi/XMBC working on the LCD either Kodi standalone, Raspbmc or Xbian?

After following this tut to the letter on a brand new image of Raspian, I find that the touch driver does not function. Anyone experience the same? Basically all I did was image a current copy of rasping, did a apt-get upgrade, and then did this tutorial. Then the touch driver does not work, meaning the pointer does not respond.

The reason I did this was because on a production version of my system I added the 3.2 screen and it worked great except for the x-axis. So I wanted to see if there was something in my system that was interfering or if this is another error. Now with a raw rasping the driver does not work at all. I wonder if the touch pin has changed since the kernel is using BCM pins instead of GPIO pin numbers?

I have exactly the same problem. I also installed a new version of Raspbian, and the LCD part works fine (except all the windows are way too large), but the touch part doesn’t work at all… I’m using Waveshare Spotpear 3.2″ V4.

I remember that I plugged in the screen wrongly one time, before configuring any of the GPIO pins. Can this have damaged the screen? Still it’s weird that the display part works well and the touch part not at all.

Touch actually goes through one of the SPI pins I think. Either the driver is toast with the required kernel update or the driver is using the wrong pin. It is very likely the this works well with previous raspian versions, but not with the new B+ and with the new kernel.

I am trying to use the sainsmart 2.8″ lcd sold through microcenter, using the sainsmart32_spi … seems to have the same pinouts, should I be able to get this to work? I am stuck at the white out screen on the lcd, doesn’t seem to recognize the module either.

Unfortunately I’ve tried that ( a few times actually) but the file still doesn’t exist. Thanks very much for the assistance anyway. I must be doing something wrong. My Raspian came from a Noobs installation, I’m wondering if I should try installing the OS from somewhere else. My LCD screen didn’t come with a CD or any docs so I’m completely in the dark here.

I have just found a way to get this file on my system! Apparently its part of the fbturbo installation. I found it here http://www.raspberrypi.org/forums/viewtopic.php?f=63&t=45746&start=75 (under experimental enhanced x driver (rpifb).. Sorry if this is obvious to everyone but I am SUCH a noob at this!!

I have the waveshare 3.5 and what to use it only as a secondary screen by putting measurement data with a c program on the screen. Is there any solution?

Ok, what am I doing wrong. I am using a fresh install of the newest raspbian, on a Pi 2. After doing the first two steps and rebooting I get the rainbow screen, then the boot up process, and then my screen just goes black with a flashing cursor in the top left. I am not able to enter any commands or anything…like the pi is halting just after boot up. Any thoughts/suggestions would be greatly appreciated. Thanks.

Well figured out that step 1 was causing my problems. I’m guessing it is shutting off my hdmi feed and trying to switch it over to the SPI, am I guessing right? If so, not sure how I’m suppose to complete the rest of the steps if my hdmi output gets turned off before the LCD is actually set up to work…that sounds kind of smartass-like, which is not my intention, just looking for some clarification on what is going on in that first step as I am fairly new to this stuff. Thanks.

Anyway, I was able to do the rest of the steps with no problem. LCD didn’t work, but I am using a Waveshare 3.5, which doesn’t look to be supported yet. Mostly I am trying to play around and see if I can get it working somehow. Anyone found a way to do this yet?

Here is a link to an updated image from waveshare. Upon install it got the display up and running, but I still do not have touch functionality. I’ve been playing around with it, but it has been to no avail…hopefully someone better at this stuff from me can get the touch working.

I am having an issue with getting the GUI back. Every time I use startx my pi just sits there for about two minutes saying “No protocol specified”, and then it just gives up. I went through this tutorial about four times now and am not certain why it is doing this. I have the exact same LCD as is in the tutotial (WaveShare 3.2b). any help would be great.

Hi I am making a project for school,using the raspberry pi b+ and waveshare spotpare 3.2b. Everything works except the touch input doesn’t work. Any help would be appreciated very much.

Thanks for the tutorial. It works, but I get the boot/command line stuff on the HDMI monitor and the LCD only comes on when I do startx. Is there a way to get everything to appear on the LCD screen?

I am trying to get this same screen to work with the image of RetroPie 2.6 and it won’t work. I have followed all the steps and nothing, please help I an kinda a noob.

I have a Tontec 7 inch touchscreen with a Raspberry Pi 2 B. After following the instructions the touch screen is functioning but not properly… The only are that works is the upper left (and only a small area of that). I tried changing the width and height in the modules but it didnt change anything. Also the xy seems to be reversed, I changed the swap_xy to 1 but again no change on the screen.

Now the OS freezes at the emulation station loading screen, and if I connect my lcd it gives me a lot of error messages which I can only see on the 3.2 inch screen.

hi i have the same screen with a raspberry pi 2 im trying to run retro pie but it wont show ..however it shows all the commands …but i cant get it to show the gui …if u guys can make an image or something please i have been in this pain for two weeks already thank you

Damn.. I thought I was kickin ass haha. I am using the SainSmart 3.2″.. the backlight is lit up and the pi was booting and everything just fine but on the final reboot it gets hung and says “nonblocking pool is initialized” ?? No idea what that means. But it’s def just frozen at this point.. on my main screen, and just the backlight is on the SainSmart.

This was an excellent tutorial. I have gotten an output to the screen, but no touchscreen usage . I have the Waveshare SpotPear 3.2 Inch LCD V4 screen, but using Raspberry PI 2 with wheezy. Any ideas?

Thanks a lot for this article. Very clear and easy . I am new in pi’s world and my 3.2″ screen is working fine. I rotate 90 º and works. I can use mouse and so on.Not problems.

I filed the steps to calibrate the screen but it did not work.I think because it did not find the TFT pin, because I think the touch problem is the assigned pin to control it changed.

I actually used the driver from here http://www.waveshare.com/wiki/3.2inch_RPi_LCD_(B) , from a new wheezy build, did nothing except enable SPI in config, install driver, and change mmcblk0p2 to mmcblk0p6 in cmdline.txt and it all worked, no drama.

Hi I managed to set up my touch screen ok but I now have the issue that everything desktop fits fine but the windows I open are all huge and I can’t remember how to change the size and cannot see the option in desktop preferences any idea what I have to do and is it at all possible to install kodi to run through the raspbian is as this would be a lot my useful than having to keep swapping os on every boot up many thanks in advanced hope you can help me

Advice to all who have the drivers from the (touch)screen manufacturer and cannot obtain those otherwise: you can skip everything and go to the update steps skipping the kernel and kernel modules update (as mentioned by the author) so that you don’t override the preinstalled drivers. I have a Waveshare 3.5″ RPi v3 (not the 3.2″ supported by notro’s drivers) and actually managed without any problems to get notro’s drivers make it work. However I am still reading about the xinput and xinput-calibrator to figure out how to include it as a kernel module so that I can compile my own kernel and add it there.

i have raspberry pi 2 with 3.2 inch rpi lcd v4 waveshare spotpear.i have done as per your instructions.the display is working but touch screen not working.error shows waveshare32b module not found as well as touch screen module not found messages.

Unfortunately I have lost the Touch facility on my Waveshare 3.5″ LCD Touchscreen? Can you offer any reasons as to why? I copied the Raspbian image to my Raspberry Pi from the Waveshare website first of all. The Touchscreen displays but is not reactive with any touch

Hi great article thanks. I am trying to get a waveshare 7 inch LCD with capacitive touch running it works with the suppled image but if you upgrade it breaks the capacitive touch. I have a sense-hat and GPS which require the latest kernel and RASPIAN image and the install program for the screen replaces the /lib/modules directory and the kernel with older ones. I need to be able to install the touch drivers into a new clean OS can anyone give me some pointers? Thanks

I should add that the screen is plugged into the HDMI port and always works. The capacitive touch is driven from the USB port which also supplies power.

For anyone who have those unbranded cheap TFT touch modules and cannot get it to work with this guide, I had success on my 3.5″ with the following steps: http://pastebin.com/89qmFbPB

So I have the original image that came with my screen and it works fine with the LCD but my problem is that I want to use my LCD screen with other distros (at this time I am trying to use it with Kali Linux with TFT support by default https://www.offensive-security.com/kali-linux-vmware-arm-image-download/) What do I have to do to transfer the needed files from the original image that WORKS with the screen and use them with another image?

I originally bought this bundle http://www.amazon.com/gp/product/B013E0IJUK?psc=1&redirect=true&ref_=oh_aui_detailpage_o02_s00 with an RPi LCD V3 and no extra documentation on the specifics on the chipset. I tried with the bftft drivers but since I have no idea what to call this screen I just suppose it isn’t supported.

After 4 lost days I just decided to get another screen, a Waveshare 3.2 (just like the one on this tutorial), I’ll follow these steps and see if it work for me.

I’ve followed your instructions and am only getting a white screen stil. I am using the Osoyoo 3.5 inch touchscreen from Amazon. http://www.amazon.com/gp/product/B013E0IJVE?psc=1&redirect=true&ref_=oh_aui_detailpage_o01_s00

I’m not sure if the Jessie kernel is compatible – can anyone please confirm or not ?? Adafruit states that their setup for TFT screens are Wheezy only ; is this a different setup ??

I am using the same LCD and followed your tutorial. Have your tested the guide lately? Are you certain that it works? I see the boot messages on console but I get white screen as GUI starts.

After I rebooted in step 3, my raspberry pi won’t boot up again. It goes thru the process of booting and the text scrolls down and every thing says “ok”. Then instead of going to GUI it just guys to a black screen on my monitor with a blinking underscore in the top left corner. Anyway to get around this? or should I start over with a fresh disk image??

That is what happens to mine also.. So long story short —> THIS SITE NEEDS TO BE UPDATED OR SHUT DOWN <— There are a hundred people on here that have all lost everything on the pi drive, and spent all day (or more) working thru this tutorial 4 or 5 (dozen) times and nothing. Just have to reinstall the os over again and again.

I have tried to set up waveshare 32b on my Pi B using the latest Raspian download. I learned a lot in the process using Windows Putty, Nano etc. I have repeated the setup process several times from scratch and included the corrections for possible overwriting. My Waveshare SpotPear 3.2 inch RPi LCD V4 just shows a white screen. Any suggestions?

I’d suggest that you use the included installation disk to make a clean install on another SD card to see if the screen itself works fine or not, then try to repeat the process of installation after upgrading

There was no disk included. I asked for drivers and was given a download link to the image file. After down loading this I tried it and still got just a white screen. The HDMI monitor locks partway though the boot. I can still log in to pi using putty from my PC.

This process worked for me except for two things. The screen only shows 25* of any page so the most important buttons are inaccessible, and now the Wifi does not work and cannot be activated where it worked fine before the reboot. Any suggestions?

Hi, I am using raspberry pi 2 with raspbian jessie installed. I the waveshare spotpear 3.2 v4. The above instructions are not working. and after completing the steps there was no display from hdmi or lcd. One things to notify is.: the etc/modules files only had i2c-dev and not snd-bcm2835.

I am trying to get this to work with Retro Pie 3.3.1 and the Waveshare3.2″ v4 but I only get the terminal on the lcd and emulation station starts on hdmi. to get it working with retro pie i just replaced startx with emulationstation. how do i get this to work?

Sir, Your post has very useful to me. i am using Tinylcd. but i cant get display. i am performing all the steps in your post. i cant get touch controller information from the product website and also i am using RASPberryPi B+ model. could u please give me best solution to my work. Than you.

Hi, what if you dont know the make of your screen, i purchased via Ebay, and it is unbranded, the contact speaks barely any English and keeps linking me to a custom kernal download.

I completed all steps except for the last one (I want it to boot to console). However, when I reboot, it never completes the boot process. I start in recovery mode and check the cmdline.txt file and it is exactly how it appears on this page. I copied the kernel info as well, but I am not sure if it correct as I cannot get to it to check. Any suggestions? I might just reinstall the OS and start over…

i installed android OS in raspberry pi 2. can i use same LCD touch screen set up for android installed raspberry pi 2 which you are used for raspbian.

Is it normal the white back light during the whole process of initializing (I suspect that during the transportation trere is a deffect)? The problem is that I missed the step #1 and I performed it at the end. Unfortunately I don’t have any monitor available right now – neither “normal”, neither LCD :))))). Is it possible turning back the system or the only option is reinstallation of the Raspbian?

I’m trying to use an original Raspberry Pi model B with a cheap 3.5 inch 320×480 LCD which allegedly was manufactured to work with the Pi and has the correct fittings to fit over the GPIO pins. The operating system is the latest, downloaded yesterday and installed with NOOBS. I can’t get past step 2 of this guidance. When I reboot after using raspi-config I can see text generated as the Pi boots, then the HDMI fed screen goes blank apart from a flashing cursor in the top left hand corner. The LCD just remains white with nothing else on it. I have missed out step 1 and rebooted after step 2 and the screen functions as I would expect. Does anyone have any ideas please?

now when it seem WaveShare release their own custom image or sources, same thing happens kernel panic. unfortunately this time around doing the same trick doesn’t save the day !

Thanks for the great tutorial. I do have a question. Once you install the drivers for the lcd are you effectively disabiling the hdmi port or is it still available to use and will the pi function with both displays. I have a pi 3

once you install the drivers it replaces the kernel by disabling hdmi output and enables it for LCD. i don’t think we have a solution to get em both working at the same time. ( you are encouraged to search for it )

Thanks for the guide, have been doing this with my son but once we leave raspi config and reboot all we get is a black screen with a flashing white horizontal line (dash). Can you help? I have looked in the comments at the end of the article but no one else appears to have this issue.

I have a raspberry pi 2 with waveshare screenn 3.5 inches. Isn’t it the same instructions. But it isnt working, all i get is a white screen, and the red led on the pi is on. The green LED isnot working.

My Rpi3 gets “ERROR: could not insert ‘spi_bcm2708’: No such device” after I enable SPI in the raspi-config.My Rpi3 is freezing on the rainbow screen after I reboot at the end of step 3. I’ve tried adding boot_delay=1 to config.txt.

if any interested, now i have a raspian image working on raspberry 3 with Waveshare 3.5, also with sdr support for dongles and FreqShow working perfectly on touch

I tried following your tutorial but I got stuck right at the first step… I enter sudo nano /usr/share/X11/xorg.conf.d/99-fbturbo.conf the whole screen is blank except for the command list at the bottom…

I’d like to find the driver software for my 7″ LCD with touch (official Pi unit) so that I can use it in buildroot. I wanted to make sure this kernel is the one before I started digging further.

Every time I reboot after step 3 I get the rainbow screen of death (lost the kernel) and have to reimage my card and start over. Anybody had this happen and have a solution?

I started through your tutorial and completed step 3 and rebooted. After the Raspberry screen and some of the boot text on my HDMI monitor, I now have a black HDMI monitor and a white screen on my LCD. Does this mean that the bootloader was overwritten or something else is wrong? How am I supposed to enter in the proposed fixes to the bootloader, when I can’t get the RPi to boot? Do I have to interrupt the boot process at some point to reinstall the bootloader or what?

Its a script. Download and instead of running sudo ./LCD4-show run cat ./LCD4-show to simply display what it does without actually running it. The commands are fairly simple modifying a few files. I actually saved the LCD-show.tar.gz on my own server for faster future download but also for backup as it saved me tons of hours (if that’s a measuring unit for time :) )

I used this link though (smaller file ~ 50 KB, fast download) http://www.waveshare.com/w/upload/4/4b/LCD-show-161112.tar.gz and replaced LCD4-show with LCD32-show in the last line.

I’m using RasPi Zero with latest (as of last week) Jessie Raspbian. Did you run the script? If it didn’t work and you have modified other files in the process of making it work, I would recommend installing a fresh installed image on a new card and running the script. Can you suspect the screen being faulty or got “burned” in the process?

i bought a 3.5 inch tft lcd screen from banggood. and i have installed raspian jessie, the latest version, in my sd card. but when i power on my Pi, only a white backlit screen comes. there are no images or graphics whatsoever.

Of course. Raspbian Jessie does not come with the drivers needed to talk to the screen. See my previous comment (September 22, 2016 at 11:54 am) and follow it.

I have done every thing right but the only major problem is that the screen is still white and my raspberrypi freezes after a line of code when booting up and I cant get in with SSH

Will your system work with my SainSmart 2.8″ 2.8 inch TFT LCD 240×320 Arduino DUE MEGA2560 R3 Raspberry Pi ? I would like to know before not be able to back out. Thanks, Lee

I know I will end up regretting this, but how do I change fb0 to fb1? I’m on the screen that has all the info, but no way to change it. Am I looking for a file? I have had my screen for MONTHS and I can’t do anything with my pi or the screen. I am >< close to smashing both. COMPLETE WASTE OF MONEY so far!!

hello. I really appreciate your blog post. I have a raspberry pi 3 B. I have been unable to get my waveshare 3.2 screen to work.I am at a complete loss for what to do. I do step 2 I change fb0 to fb1 and then follow your directions I don’t get the prompt to reboot; however, I do it manually with sudo reboot. that works fine then I complete step three and that works just fine; however once I reboot from getting those drivers and when I attempt to reboot it is unsuccessful and then my whole raspberry pi will not restart. then when I power it back on it will just shut back off. I then have to redo noobs onto a new SD card I would GREATLY appreciate anyones help

I ‘m actually using a LCD Waveshare3.2” , I followed your steps to setup the lcd touchscreen for my rpi and it work but I have a problem with the resolution because if I open a repertory I do not see the whole contents on the screen .

hi! thank you for this post…. I was wondering if all the raspberry pi’s gpio are being held by this screen or do we have any of those availables for use??

it worked. but the resolution is for bigger screens. i got the menubar small, but the rest appears too big , and out of screen. the wastebasket icon is 1/6 of my 3.2″ screen. wich HAS the resolution capability too display the whole desktop. But i’m a PI newby and dunno how to adjust the screen resolution on this display. anybody?

hey Thanks for this good post …I have capacitive touchscreen which i brought from the link below..can you guide how i can configure the kernel modules…It will be very helpful for me…Thanks

I did a 5inch LCD for my raspberry pi. I dont use the touchscreen so i didnt have to install any drivers. It works out of the box but doesnt cover the whole screen unless you open the terminal and do:

HI I have my RPI running Pi Presents on a view sonic TD2230 Touchscreen. It all works fine, touching the click areas can navigate you thru my presentation, The problem arises when you use multitouch gestures like you would on a iPhone. Pinch or expand etc… and then all touch ability goes away. I can still control the presentation via a mouse, but I don’t get touch control back until I either relaunch Pi Presents, or if I unplug and plug the usb cable going to the touchscreen.

Could you provide me with a os image of open elec that you already built for the waveshare spotpear v4 3.2 inch touchscreen,because I cannot make sense of your website’s instructions?

In the case of the WaveShare driver, their setup script from their “LCD_show” repository will copy a device-tree overlay to /boot/overlays/ that provides most of the module config etc via boot-time device-tree patch.

(1) After the LCD driver is installed, the system will automatically restart. After the startup is successful, the LCD can display and touch normally,

After execution, the driver will be installed. The system will automatically restart, and the display screen will rotate 90 degrees to display and touch normally.

Raspberry Pi leads out 40 GPIO pins, while the screen leads out 26 pins. When connecting, pay attention to the corresponding pins and Raspberry Pi pins.

5) Insert the TF card into the Raspberry Pi, power on the Raspberry Pi, and wait for more than 10 seconds to display normally. But the touch is abnormal at that time, and the touch needs to be calibrated as the following steps.

3. After reboot, touch will work normally under normal circumstances. But for different resistance screens, the accuracy of using the default calibration parameters may not be very suitable.

You can perform touch calibration by clicking the Raspberry Pi icon on the taskbar, selecting Preferences -> Calibrate Touchscreen, and following the displayed prompts.

4. After calibration, the following data will be displayed. If you want to save these touch values, you can replace the data in the red circle with the data in the corresponding position in 99-calibration.conf.

The installation of xserver-xorg-input-evdev and xinput-calibrator in Ubuntu system reports an error, so the touch cannot be used normally. How to solve it?

In industrial applications, the major functions of HMI are real-time information exchange between humans and production equipment via programmable logic controllers (PLCs), variable-frequency drives (VFDs), and meters. HMI screens display data, provide visual feedback, and execute operational commands via an input device such as a touchscreen, keyboard, or mouse.

The rise of Industry 4.0 and IIoT has transformed automation, leading to a global intelligent manufacturing revolution that shifts the paradigm from “automation” to “intelligent automation”. In the production lines of smart factories, different sensors are built into manufacturing equipment to automatically check product quality and capture device data. HMI devices aggregate data and simply process the information for a more efficient and productive system. Additionally, according to the needs of cloud applications and intelligent manufacturing, factory management and production decisions are more reliant on visualized control platforms. HMIs simplify and visualize data to make it intuitive to understand at first glance. Industry 4.0 transformation integrates IT and OT systems to share and use the management data in MES or ERP systems, and the production data in production equipment to achieve a more flexible and efficient manufacturing process. HMI devices not only perform the role of machine monitoring but they are also the hub for data processing and transmission between IT and OT systems.

To fulfill data visualization needs from edge computing, choosing a right HMI can enhance factory automation and ensure productivity. Here is the checklist to review your application from different viewpoints to help you to find the correct HMI solution:

For factories built in extreme environments, or the applications exposed to wide temperature variations, HMIs with a wide operating temperature range will ensure stability. Advantech provides all kinds of

A waterproof HMI is generally required for applications with high standards of hygiene and cleanness, such as in food and beverage manufacturing, and medical industries. The HMI waterproof level is classified by an IP Rating (Ingress Protection Rating) depending on the protection degree against foreign bodies (tools, dirt etc.) and moisture. Advantech provides an

Industrial environments face conditions like dust, debris, and vibration, so an industrial grade design HMI can promise durability and a long life. For some outdoor scenarios, a HMI with sunlight-readable screen is essential so Advantech provides rugged designed industrial panel PCs (

HMIs with high computing power are needed for applications processing big data or high resolution images, such as defect inspection applications used in quality control processes for the food and beverage industry, data and image calculation used in electronics manufacturing, and face recognition technology for people working in public places. Advantech provides premium industrial panel PC solutions, including the fanless touch panel PC

On the other hand, if the data computing requirement is lighter, a thin-client terminal HMI with lower power consumption and lower cost is recommended. Additionally, if the panel PC is to serve as a web terminal, a web-browser terminal HMI series is suggested for its embedded browser and rapid Web App development features. Advantech provides cost-effective

Industrial panel PC solutions with built-in apps or HMI software are also value-added choices. For example, Advantech provides a software bundle for TPC/PPC series integrated with Advantech developed HMI software. HMINavi supports easy PLC connection and data visualization, and WISE-IoTSuite/AppHub web-based solution facilitates remote device management.

Lastly, Edge-as-a-Service (EaaS) solutions offer real-time insights and localized actions for your edge computing environments. Advantech’s Edge Intelligence solutions establish an EaaS ecosystem that combines hardware, edge services, and cloud platforms for device control, edge monitoring, and software management. In this architecture, all process and application data can be aggregated and visualized on dashboards for users. The platform portal employs container technology that can be implemented on all Advantech IT gateway devices. Moreover, the portal’s secure open-software architecture enables users/ developers to access the system via a HTML browser and allows users to integrate unique analytics and connectors.

HMI screen sizes are one of the factors to be concerned about. Usually small screen size HMIs are used for single machine control; medium sized HMI screens for facility management and connected to the MES system; and large HMI screens are perfect for remote management in control rooms. However, for smart applications, data visualization is needed, so bigger HMI screens with higher resolutions and 16:9 aspect ratios are becoming mainstream. Advantech provides various sized industrial panel PCs and monitors to support all kinds of factory applications from automation control to field data management.

HMI touch screen type choices depend on the users’ requirements. If the application requires precise and accurate multi-touch capabilities such as zoom, drag, swipe, and pinch touchscreen gestures, projective capacitive (P-CAP) control touch screen types will be ideal. If the operator needs to wear gloves, then resistive touch screen (RTS) types will be preferred.

HMIs that feature physical buttons are still needed for certain user demands. Since touchscreen HMIs do not provide tactile feedback like button-based HMIs, without tactile feedback, users lack keypress confirmation of touch commands, which is particularly important for those with visual impairments. Physical buttons are also helpful for eliminating issues encountered when using touchscreen HMIs: namely difficulty distinguishing graphical onscreen changes under sunlight, shifting, and unclear targets, and the need to look at a screen when performing important tasks. The existence of physical buttons allows users to quickly and accurately complete tasks. Advantech’s

This application note is part 2 of our 2 part TFT LCD screen series. Part 1 discusses configuring the screen resolution of a TFT with a Raspberry Pi. Part 2 discusses calibrating the touch screen of a TFT. Click here to read part 1.

After the display is setup with the Raspberry Pi you may want to calibrate the touch feature for accuracy. The display used in this example is a 7” TFT with capacitive touch (E70RA-HW520-C). This is a continuation of a previous application with the same display. The touch feature is auto enabled upon download of the Raspbian software; however, it may be inconsistent with actual motion. Calibrating the touch feature of a display can be done in just a few simple steps.

Next, we find the program that calibrates the display. There are a few options of programs that calibrate the touch setting, the one I will be using is called ts_lib. We can install this through the Terminal. Root privileges will need to be enabled to install the program that is used. Enable super user mode by entering:

This will install a configuration file for the touch screen. Before the test we need to specify which device we’re using and where it is located. The display is located at “event0” as verified in the previous step. This could be a different value for you depending on the setup so be sure to refer to the results of step one. Enter the following commands to define the display variables.

Now we can run the calibration test. To do this enter the ts_calibrate command in the Terminal. You will need to be in super user mode for the calibration test to run. A screen will pop up asking you to touch five different points on the screen, try to touch them as accurately as possible. After the test is finished a list of the results will be displayed in the Terminal.

The touch screen should now be configured to a precise setting. This is just a brief overview of how to calibrate the capacitive touch feature of a display. For further calibration settings you can visit the “ts.config” file. You can open this file from Terminal by entering:

I"ve been looking around for a small HDMI LCD screen to use as a seconday screen with Windows and it took a few months of research on and off before deciding on the Elecrow 5" HDMI monitor. For the most part, it took me a while because a lot of reviews here and on other sites were primarily about use and config with Raspberry Pi.

Thanks to reviewer Alan who gave a good review with plenty of photos that convinced me to go for it. Not sure if it"s just how Amazon stores user review videos but the video review was a bit pixelated so it was hard to appreciate the clarity of the screen but it seemed to be what I was looking for.

Having used it for a few months now I still can"t believe how clear and sharp the screen is! There are sadly no controls for brightness, colour, saturation or contrast but everything displayed looks very nice and accurate.

As I"m using this with Windows, I"ve not needed to look through the included driver utility disc and not tried the resistive touchscreen so I can"t comment on those. Windows just detects it as a second display and lets me extend my desktop. No drivers needed. The box contains the LCD screen, a HDMI bridge connector that neatly connects the HDMI socket on the top of the screen to the HDMI socket on the Raspberry Pi when mounted together. Standoffs for mounting are also supplied plus a plastic stylus.

+ It shows the video feed straightaway without any fancy splash screens or slow initialisation pauses. This was one of the annoyances with Lilliput monitor was a slow bright blue screen on power on before it would think about showing the feed. I know it"s only a few seconds but I specifically wanted instant feed on power on for future uses.

+ I was hoping for an on/off switch but no it only has a backlight switch which I wasn"t sure about to begin with but I"ve since found it very useful and better. I was thinking about buying a micro USB cable designed for Raspberry Pi with an inline power switch built in but for now the brightness switch is fine. As a blessing in disguise, it prevents Windows/DirectShow from blinking all screens when it realises a monitor has been disconnected, that blink would often cause the video on my TV app to freeze. Turning off backlight doesn"t cause DirectShow to have a fit.

- The only negative I can think of is the availability or lack of screen cases with cutouts to suit the position of the HDMI and USB sockets on this. The Elecrow has its HDMI and USB socket at the top edge of screen and nearly all cases I have looked at are designed for screens with HDMI and USB on the right edge. I"ve had to import one from China that had the cutouts for this screen. Took about 2 weeks to arrive. Wish I"d have ordered two cases at the same time to avoid the wait as I"m impressed with the clarity of Elecrow I hope to buy another one in near future.
