sainsmart 3.2 tft lcd raspberry pi wiki supplier

The 3.2 inch TFT LCD module is a special design for Raspberry Pi for portable application. It features a 3.2” display with 320x240 16bit color pixels and resistive touch screen. The LCD is well mated with Pi board and interface with Pi via the high speed SPI port, and support console, X windows, displaying images or video etc. It also provides 4 press buttons for user defined functions.

RPi LCD needs to use a SPI interface, but in the original image file of Raspberry Pi, the displayer is driven via a HDMI port. So the original image is not applicable for RPi LCD, and you should install the LCD driver to your Pi or use the Ready-to-use image file provided by Sainsmart,click here.

Download the LCD driver and extract it to your Raspbian OS (e.g. copy the driver to your Pi by sftpor using U disk). Then run the following command via putty:

This LCD can be calibrated using a program called xinput_calibrator which is pre-installed on the offer image. However, it was not pre-installed on original Raspbian OS. So in this case, you should get and install the program manually with

After running these commands, there will be a prompt for four-point calibration shown in the LCD screen. Click the points one by one to finish the touch calibration. Then, the new calibration data will be displayed in the terminal, as shows below. Please get these data for future use.

The 3.2 inch TFT LCD module is a special design for Raspberry Pi for portable application. It features a 3.2” display with 320x240 16bit color pixels and resistive touchscreen.

The RPi LCD can be driven in two ways: Method 1. install driver to your Raspbian OS. Method 2. use the Ready-to-use image file of which LCD driver was pre-installed.

2) Connect the TF card to the PC, open the Win32DiskImager software, select the system image downloaded in step 1 and click‘Write’ to write the system image. ( How to write an image to a micro SD card for your Pi? See RPi Image Installation Guides for more details)

3) Connect the TF card to the Raspberry Pi, start the Raspberry Pi. The LCD will display after booting up, and then log in to the Raspberry Pi terminal,(You may need to connect a keyboard and HDMI LCD to Pi for driver installing, or log in remotely with SSH)

1. Executing apt-get upgrade will cause the LCD to fail to work properly. In this case, you need to edit the config.txt file in the SD card and delete this sentence: dtoverlay=ads7846.

This LCD can be calibrated through the xinput-calibrator program. Note: The Raspberry Pi must be connected to the network, or else the program won"t be successfully installed.

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:

I just tested this, and it looks like the difference is how SPI is enabled. In the RPi 2 it’s enabled in raspi-config, not commented out in the blacklist file. I just updated the post so it should work now!

Looks like the only difference is in how SPI is enabled. In the new release of Raspbian, SPI is enabled in the raspi-config menu under advanced settings. In older versions of Raspbian, it is enabled by commenting out the line in the blacklist file

Unfortunately, their “driver” is an SD card image containing a complete installation of Raspbian which has been preconfigured to use their display. Which is fine if you’re setting up a brand new system that doesn’t need to be a specific distro, but if you’re trying to add the display to an existing Raspberry Pi, already configured the way you want it, with software installed and data present, or if you want to use a specific distro such as Octopi, then it’s not terribly helpful.

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 ?

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.

Unzipped it and looked around. From a shell script inside i kinda figured out what it was doing. I didn’t like what I saw, so I manually made changes omitting the parts I didn’t like (it rm -r my /lib/modules directory… omitted that part) and copied 2 files and 1 directory from the OEMs archive to the file system of my Pi2.

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.

i have a watterott display (https://github.com/watterott/RPi-Display) and changed the device-name to “rpi-display”. i use a rsapberrypi 2 and hae the latest raspian image installed.

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)

Any ideas what going wrong? I am using the latest “2015-02-16-raspbian-wheezy_zip”. Enabled SPI. done all the steps. Even changed mmcblk0p2 to mmcblk0p6 as suggested by Dabomber60 (but that freezes for me)

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

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).

Thank you so much for this great tutorial. I have my WaveShare SpotPear 3.2″ V4 working fine on my Raspberry Pi 2. If you are having problems with this specific hardware, skip step 5.

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?

in the video you say to change the existing line to “snd-bcm2836” for the rasppi2 which isn’t listed in the written part of the instructions (part 4).. this should be added (I believe it caused me to have to re-image the OS again, the Pi wouldn’t boot to anything just using the written steps)

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.

I do not think that has anything to do with it. Other than power pins, the rest are communication. If it still works then you are good. No, there is something else. I do suspect it us related to the BCM pin numbering. The real question is… Why isnt the eeveloper responding? I have since abandoned this TFT because of his lack of response.

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.

The SainSmart 3.2 sold by MicroCenter (20-111-971) is actually the exact same WaveShare SpotPear v3 documented here. So maybe your 2.8 would work if you tried a WaveShare driver?

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!!

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?

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

well ,,i follow all instructions and still kernel panic ,,,,may i request from mr. Circuitbasics@Gmail.Com that have a contact with manufacture and just ask for 2-3 links for image files for different versions of pi till all this f discussions are finished,,i cant understand 10 guys said we run it and 40 guys said kernel panic ,,as an expert i did 50 times imaging and follow all changes fro this forum and other forums and still cant run it ,,,so sth is wrong …..just asking the manufacture for simple f image ,,that`s it ,,,,simpleeeeeeeeeeeeeeeee

well i did it at last on pi 2,,after reading 100 pages and reimaging 50 times ,,i finally find the solution ,,,,there is a simple line forgotten to be attached in setup instruction,,,well i give u clue for prodigies ,,there is a step left between step 3 and 4,,,,and a simple change in step 5 according to your pi version ,,,that`s it ,,nothing else,,,,

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.

Hey! i did this and rotated it… It loads console perfectly, but when it goes into startx, i get a black background with only the wastebin/trashcan… how do i get the taskbar(or whatever that bar is called)? and the raspberry background?

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

I have purchased a raspberry pi B+ total kit and waveshare 3.2 TFT display online. In the package i have been given a pre-loaded NOOBS installed SD card. I did not even start anything yet. What should i do what r the things needed and how to connect the display i really want to know. I need help as i don’t know anything. Does the above solution help or will u suggest something………………..

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

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

I have the WaveShare 3.5 (A) and cannot get it to work with the Kali Linux with TFT for Raspberry Pi. Have anybody gotten the A to work? (Not the B, theres instructions for the B already and dont work with A)

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’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.

Oct 16 17:38:48 spare kernel: [ 12.544859] graphics fb1: fb_ili9340 frame buffer, 320×240, 150 KiB video memory, 4 KiB DMA buffer memory, fps=50, spi0.0 at 48 MHz

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.

Please check out my answer, it may help you if it works. I’m not in that case but I’m assuming that the desktop environment simply doesn’t automatically start running anymore… This can be changed in the raspi-setup

Try typing ‘startx’ if you problem isn’t solved (assuming you’re using Raspbian and LXDE), it should start the desktop environment you’re used to see. What you’re seeing is the Command Line Input interface (CLI), the most basic way to interact with a computer. Hope I helped you a little

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?

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.

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.

what if OS is not Raspbian, any other distro like Yocto project, etc.? Could you please specify process without “rpi-update” that makes driver installation process more generic, not dedicated to Raspbian.

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 have KeDei 3.5 inch TFT version 4.0 by Osoyoo. (released after January 1 2016) how do i get it working with vanilla Raspbian Jessie (do not want to install the image sent by the seller)

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?

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

ads7846_device model=7846 cs=1 gpio_pendown=17 speed=1000000 keep_vref_on=1 swap_xy=0 pressure_max=255 x_plate_ohms=60 x_min=200 x_max=3900 y_min=200 y_max=3900

No matter what I do, I can’t get this to work. It works perfectly fine on my Pi2, but when I follow and use the guide on my Zero, I always end up with the activity LED blinking 8 times (corrupt SD/filesystem error).

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.

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.

The owner of this article should including a WARNING in the header that if someone follows the steps, they will install a deprecated driver (which is only visible as tiny text on its gethub page here https://github.com/notro/rpi-firmware). This driver after install will break Raspberry Pi and the SD card will need to be reimaged, for some less experienced users, this could also mean lost work if they failed to backup their code or resources. On windows, it requires installing Linux reader software and it takes a long time to fix this f**kup which could easily have been avoided if the author had and sense of responsibility.

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?

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?

Much of this is outdated on Raspbian Stretch where device tree overlays (see https://www.raspberrypi.org/documentation/configuration/device-tree.md) provide for most of the configuration automatically.

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.

After I did the step that “INSTALL THE FBTFT DRIVERS” and then reboot, my raspberry pi couldn’t boot successfully and the green light is always on, could you help me solve this problem? Thank you.

19-Apr-2012: Now that the Model B board is shipping, details added should relate to this board and the default Debian distribution unless stated otherwise. A suggested suffix markup scheme is as follows:

The original Model B board had current limiting polyfuses which limited the power output of each USB port to approximately 100 mA. USB devices using more than 100 mA had to be connected via a powered hub. The Raspberry Pi"s PSU was chosen with a power budget of 700 mA of which 200 mA were assigned to the USB ports, so the Raspberry Pi"s (poly)fuses were designed only for devices up to 100 mA, and typical 140 mA polyfuses will have as much as 0.6 volt across them when drawing currents near the 100 mA limit. As a consequence the USB ports are only directly suitable for "single current unit" USB devices which, according to USB specifications, are designed to work with just 4.4 Volt. Not only do non single current unit devices draw more current (causing greater Voltage drops, and greater stress on the fuses), they also might require 4.75 Volt to work.

Shortly after the Raspberry Pi was released it was confirmed that there were a number of issues with the Linux USB driver for the SMSC95xx chip. These included problems with USB 1.x peripherals that use split transactions, a fixed number of channels (causing problems with Kinect) and the way the ARM processor handles the SMSC95xx interrupts.

You will usually want the alsa package for sound. In the Debian image for Raspberry Pi (and possibly other distributions) USB sound cards are prevented from loading as the first sound card, which can be an annoyance if it"s the only device you have. To disable this behaviour edit /etc/modprobe.d/alsa-base.conf and comment out the last line; options snd-usb-audio index=-2 . If you are not user pi you may need to add your username to the audio group thus: sudo adduser yourusername audio (user pi usually belongs to this group anyway).

DVB-T205, based on rtl2832u chipset, worked with this driver on older 3.2 kernel. Couldn"t get same device working reliably on current kernel. (On the older 3.2 kernel it worked with Saorview (Irish DTT service), both HD & SD.)

TV28T v2 USB DVB-T & RTL-SDR Receiver, RTL2832U & R820T Tuner, MCX Input. DVB-T works with OpenElec 4.2.1 connected to the PiHub, tvheadend backend + frontend, finds all expected, non-encrypted channels in the south of Germany. I did not try to use the remote.

Mystique SaTiX-S2 Sky USB: Scanning/watching SD and HD works via vdr and streamdev plugin, watching on the Raspberry Pi directly is laggy as hell. DVB-USB and I2C support must be enabled in the kernel. Needs drivers/firmware from here.

K-World UB499-2T Dual DVB-T USB Tuner. IT9137 chipset. With no other USB devices connected Raspberry Pi can just about power this stick. IR and supplied remote work with XBMC.

Technisat_SkyStar_USB_HD. Instructions: http://www.linuxtv.org/wiki/index.php/Technisat_SkyStar_USB_HD Used the Raspberry Pi to receive and redirect it via network to another host. Didn"t try to play back the stream on the Raspberry Pi itself. Tested with Astra 19.2E radio and SD-TV channels

TT-TVStick CT2-4400 USB Fernbedienung rev2. DVB-T works with OpenElec 4.9.4 BETA connected to the PiHub, tvheadend backend + frontend, finds all expected, non-encrypted channels in the south of Germany. DVB-C also works, finds around >30 TVs and >100 radio stations. I did not try to use the remote, nor did I listen to any radio station. TV works, SD channels are ok, HD channels jitter. tvheadend backend crashes often within OpenElec 4.9.4 BETA, but restarts, so still buggy but looks good(BETA!). It did not work out of the box with the stable OpenElec 4.2.1.

GlobalSat BU-353 Does not require a powered hub, works fine when directly plugged into the Raspberry Pi. On Raspian, requires the gpsd and gpsd-client packages. For some reason, the gpsd daemon does not always start correctly on boot. You may need to do something like the following to manually restart it:

A USB UART adapter is used to access the serial console of the Raspberry Pi from a development host such as a laptop or desktop PC. The USB end connects to the PC and the UART header end connects to the USB. While it is possible to connect the USB end to another Raspberry Pi, this configuration has not been tested unless explicitly mentioned against an individual entry below.

A USB to Serial (RS-232) adapter is used the other way around, ie. the USB end connects to the Raspberry Pi and the RS-232 end (DSUB-9 or DSUB-25 pin) to the other device which may be another computer, (old) modem or printer, or some electronic test equipment.

FG-U1232-PL2 Based upon the Prolific PL2303X chipset and listed by lsusb as ID 067b:2303 Prolific Technology, Inc. PL2303 Serial Port. Appears as /dev/ttyUSB0, and requires the user to be a member of the dialout group (which pi is for Raspbian Wheezy). Initially tested using an old RS Datalinker setup in "loopback" mode via microcom upto 9600 baud, and gtkterm after installing that from source code. All handshake lines toggled as expected and no characters were lost. Subsequently gtkterm was used to check bi-directional communication with an ancient brother EP44 electronic typewriter (as a printer/dumb terminal) at 1200 baud. Signal lines were again monitored with the Datalinker.

Based on the Prolific PL-2303HX chipset. Listed by lsusb as ID 067b:2303 Prolific Technology, Inc. PL2303 Serial Port. Appears as /dev/ttyUSBX with GUID dialout so your user has to be in that group. If not, sudo usermod -a -G dialout yourusername will add your user to the dialout group. Works great with screen /dev/ttyUSBX 115200 to connect from your workstation to your RPi.

CH340 Chipset - Currently not supported by RPi but there is a patch of kernel code here, but it is for a 2.X kernel. If you find you have bought one of these, then it may work under Windows, but as of writing there is no support for RPi. Otherwise you can have a go at getting the patch to work.

PL2305 Chipset with Centronics 36w connector. Originally purchased for use with a netbook and connected to an old Canon BJC-250 printer. Worked fine under RISC OS Raspberry Pi with its in-built BJC-250 driver. Could not install the CUPS drivers etc. for Wheezy-Raspbian initially, but was able to do so for Wheezy-armel. Once I"d updated/upgraded Wheezy all was fine.(See notes at CPM-Spectre-Pi...USBtoParPrntAdapter for more info. and also a CUPS/Wheezy installation guide)

2.5" SATA HDD USB Adapter with silicone HDD sleeve. Model: USB-ADT-25SATA. Works on powered Hub, not directly to Raspberry Pi. Built-in "Y" power adapter. Does work direct on some ver2.0 boards if used with 5.25 power supply, or Y adapter

Initially would not work when plugged in directly to Raspberry Pi. Worked when connected via an unpowered Trust hub. Worked after Raspberry Pi was modified with 10K resistors over the USB polyfuses (warranty invalidated). Probably would work fine with powered hub.

To make it working deploy the Futronic libScanAPI on your Raspberry Pi (example code and instructions included): Media:ScanApi_armlinux_RPi_gnueabihf_gcc472_update1.zip ‎

Futronic has released an updated API. This works with their newer "H" model scanners (updated CMOS). This means the FS80H and FS81 (the OEM version of the FS80H) will now work with the RPi (I tested this myself).

Unbranded active converter known as the "blue cube". Based on the Cypress CY7C63723C 8 bit RISC. Please see http://geekhack.org/showwiki.php?title=PS2-to-USB+adapters for more information.

Note that although the adapter might work, PS/2 keyboards were not designed to be low power USB devices, so they might not meet the requirement to work with considerable lowered supply voltage (4.4 volt) provided by the USB ports of the raspberry PI. These keyboards should work when powered by a powered hub.

The Raspberry Pi does not have a power on/off switch as standard (it does have a reset switch), however some add on boards have been developed to cater for this need.

The Pi Supply Switch is an on/off power switch for the Raspberry Pi which includes a hard on and off switch and a soft shutdown switch for the Pi, making it easy to manage power on your Pi. They were recently successfully funded on Kickstarter.

The RemotePi Board is an intelligent infrared remote controlled power switch add-on board for the Raspberry Pi. It allows to switch power on and off using any button (configurable in learning mode) of an existing standard IR remote. Power is only cut after notifying the OS and giving it time to shut-down. It is mainly intended to remote control (using LIRC) and power off/on a mediacenter system. i.e OpenELEC, Raspbmc, XBian, RasPlex, Raspbian. The board is compatible to simple GPIO IR receiver and piggy backs onto the Raspberry Pi, no soldering required. For more information click here.

The Raspberry Pi uses a standard Micro USB (type B) power connector, which runs at 5 V. Generally you can use a MicroUSB to USB cable and then either power the Raspberry Pi directly from your main computers USB ports (if they provide enough power), or by using a USB to Mains adapter. A number of mobile phones use MicroUSB power cables, and these are compatible with the Raspberry Pi in most cases. Below is a list of power adapters known to work.

There is now a 5.25V 1500mA power supply manufactured specially for the Raspberry Pi to account for voltage drop due to the high current draw of the Raspberry Pi when compared to typical (phone charging etc.) duties.

Note that apple designs its charger products to work optimally as chargers. In practice this means that apple chargers drop their output voltages somewhat with output current, so that the charging circuits do not need to dissipate more heat than is strictly necessary. Because of this, and although many people have reported apple products to power their basic PI setup reliably, its still not an optimal choice for a PI system that uses power hungry USB devices. Also, because of the popularity and high price of these chargers there are many very sub standard, but almost impossible to recognize as fake copies on the market, and some of these fakes are about the worst things you can try to power your PI with! Not only do they not work, they may actually be dangerous to use!

5 V 550 mA curve 8520 charger works with raspberry pi Model B Board v. BS1233. It does not work with Raspbmc image.Symtoms are frequent key board and external hdd disconnects.

Model: CYSK10-050200 fast charger with 5V 2000mA output, tested with USB WiFi, USB flash drive and USB wireless KB&MS connected. RPi users in China mainland can use this power adapter.

5 V 2x1 A Dual Charger Model TR9202-MICRO. Typically provides 4.8 V at 1 A per output. Can be used to power a Pi and, via a separate cable, a USB 4-port hub

5.25V 1.5A Raspberry Pi USB Power Supply Specially designed for the Pi. Comes in 4 varieties for worldwide compatibility - UK, European (EU), American (USA) and Australian (AUS).

Dual USB Wall Plate. Has a 2.1A "Tablet" port, a 1A "Phone" port and a US electrical outlet. Powers a Raspberry Pi 2 from the 2.1A "Tablet" port. Available from Five Below. Link

38113BBR Juice Pack Powerstation 4000 mAh: output 2.1 A max: included charging cable powers RPi, 7.5 hrs light use w/keyboard and mini-Wifi on RPi ports

iEP387 Dual-Port 7000 mAh External Power Bank (The charging lead can be used to connect the Tecknet to the Raspberry Pi. Ran the Raspberry Pi with Wi-Fi dongle and wireless keyboard receiver for over 9 hours of light use.)

iEP390-9000mAh External Power Bank (The Power Bank has been verified working with RPI3 with on-board Wifi and HDMI out. Additionally, the Power Bank supplies power to RPI continuously without disruptions even when the Power Bank is connected / disconnected from charger -> it can be used as a cheap UPS)

Note that active converter boxes may draw power through the HDMI port, and thus will put an extra load on your PSU, and also increase the current running through the Raspberry Pi"s primary input fuse. HDMI ports (and the raspberry PI) are designed so that they deliver a very limited amount of power (50 mA) to the TV/Monitor/display-adapter and much more isn"t in theory allowed. In fact there is a diode (D1) in series with the power line which can only handle 200 mA, if the adapter tries to draw much more than that the diode might fail. Therefore only externally powered adapters are to be recommended. Despite this, many people report success with non externally powered devices. If you have bought a non externally powered HDMI to VGA adapter, and you experience problems with it (It behaves badly, D1 burns out, F3 "blows", or your PSU overloads), then not all is lost, there are cheap (a few dollars) adapters that allow you to add external power to the HDMI cable! An example can be found here: [13].

There are three kinds of DVI. There is DVI-D, a digital signal fully compatible with HDMI, so a passive cable can be used. There is DVI-I, which is a connector with both analog pins and digital pins. An HDMI to DVI-D adapter fits in a DVI-I female connector. Finally, there is DVI-A. This a fairly rare connection, but occasionally it will be found on some monitors and is an analog interface, in fact the same as VGA! In any case, you may need to change config.txt hdmi_force_hotplug=0 to =1 if your display does not receive DVI signal (the analog output is likely active).

Some adapters like Farnell part AK-CBHD03-BK are HDMI to DVI-I, which, while not fitting in a DVI-D monitor, are still compatible. The analog pins simply must be bent.

A generic HDMI-to-DVI converter from eBay. Works well, but it"s probably the cause of some power loss between the Raspberry Pi and the monitor, causing this problem. A setting of config_hdmi_boost=5 in /etc/boot solved this. Note that config_hdmi_boost=4, as suggested in the troubleshooting guide, helped, but it did not solve the problem completely.

But normally HDMI cables never carry analog signals and the PI surely doesn"t output analog signals either, almost no HDMI output device does, as its completely against HDMI specifications.

HDMI to VGA converters do work, they convert the digital serial data streams from HDMI and using complex logic, and digital to analog converters they convert the HDMI signal to the analog signals needed for VGA, and sometimes also convert HDMI audio to an analog stereo signal. But note that if they feed off the PI it can cause a problem, as the PI only is designed to provide about 50mA to the (HDMI or DVI-D) monitor, and these adapters use >200mA, while the absolute maximum the PI can let through is 200mA.

It seems unlikely any of these HDMI->VGA converters could be used for driving a SCART RGB SD CRT TV with a suitable lead (as shown here for ATI/Nvidia PC output http://www.mythtv.org/wiki/RGB_Scart) because they only output preset progressive resolutions, whereas the TV will need an interlaced resolution and probably custom timings.

Under six pounds with free international shipping [14] makes this worth the delivery time of just under 3 weeks. Works out of the box at 1024x768 without editing config.txt (I"ll try editing for full HD later). Spec. says upto UXGA and 1080p with 10-bit DAC at 165MHz/1.65Gbps. Raspberry "tvservice -a" reports that it supports audio up to 192k at 24-bit. Sounded fine on my tiny speaker. Comes with 3.5mm stereo plug-to-plug cable and USB to mini barrel jack power cable which it doesn"t need on the Pi. Ran mine for ages without the external power and the Pi"s HDMI regulator never got more than 34 degrees C. Adapter weighs only 14.8g and can plug directly into the Pi or even via a 90-degree "elbow" which I prefer to use. VGA signal is good enough to run 2 displays at once using a cheap splitter cable. After brief testing with good headphones, it seems there"s some definite noise on a signal of 17,500Hz and 18,500Hz is distorted. In contrast, the RPi"s own analogue sounds clean at 17,500Hz. So you couldn"t consider this an alternative to a good USB DAC.

At under ten pounds this one [15] is one of the cheapest, but perhaps due to a more advanced design is seems power frugal enough to most often work well with a Pi, it has many comments saying it works well with the Pi, and gives tips on how to edit config.txt.

According to user "Tom1989" the same Neewer HDMI to VGA adapter burned out BAT54 Schottky diode D1 on the Raspberry Pi and broke its HDMI output: Serious HDMI Problems. What"s that smell? Burning Raspberry!. On that thread, "mahjongg" suggested the NXP (or equivalent) PMEG2010AET as a high-current replacement for D1. The PMEG2010AET has 1 A max forward current, much greater than the BAT54"s 200 mA limit which may be exceeded by your HDMI -> VGA converter. Remember that the converter"s current must come from your Raspberry Pi power supply and go through the Micro USB cable and polyfuse F3, so you may get extra voltage drops and/or cause F3 to trip depending on how much current the converter uses. As always with board modifications, YMMV. Also on the same" thread, user "pwinwood" reported the Neewer"s current to be 400 mA, which is twice the limit of BAT54 diode D1. "pwinwood" also took the Neewer apart and added its own +5 V connection adapted from a USB cable, which bypasses Raspberry Pi"s Micro USB cable and polyfuse F3.

HDFuryPro HDMI to YPbBr/VGA Converter found on Amazon -- [16] -- Works with Raspberry Pi. Tested against a Philips 170B 1280x1024 LCD monitor, producing a full native resolution image. Not tested against a Component Video TV yet, and audio has yet to be got working.

HDFury1 1080p HDMI to VGA Converter from HDFury.com. I"m not sure the HDFury1 can be got a hold of easily nowadays, I happened to have access to one to try out. HDFury2, 3 and 4 are available as far as I can tell, but it is very pricey compared to the alternatives. HDFury1 was around £80 when we bought one for a project at work. HDFury2 seems to be around £130, 3 and 4 are getting on towards £200 or more. So not to be recommended as a solution unless you happen to have one lying around. I don"t believe there is any relationship between the company that produces these and the HDFuryPro I bought for myself (See above). I didn"t alter any config settings, just plugged it in. It doesn"t work without having its external power supply connected, as it requires 0.4 A, which is too much draw for the 5 V supply available from the HDMI socket on the Raspberry Pi. Its power LED lights, but no picture is produced. In comparison to the HDFuryPro this picture from this device is sharper, but it is not enough to justify the extra cost.

Turn on the RaspberryPi with the adapter plugged into the HDMI port and the microUSB cord plugged into the adapter. Having the microUSB cord plugged in is critical for it to work. With the Pi still on, unplug the adapter from the HDMI port and remove the VGA cable from the adapter. Now unplug usb cord from the adapter and immediately plug back in. Only the microUSB power cord should be plugged in. Now plug the VGA cord back into the adapter. Both the power cord and the VGA cord should be plugged into the adapter. Plug the adapter back into the HDMI port. Now it should be working. From playing around with the device on my laptop I found that the adapter needs power to be able to tell what the resolution of the VGA monitor is. If it is unable to find the VGA resolution it will not work. Unplugging the HDMI, VGA, and power cord seems to reset the device. Plugging the microUSB cable in seems to turn on the device, allowing VGA resolution detection to work. This method will probably work by just starting the Pi with no adapter plugged in, then just plug in the microUSB, VGA, and HDMI cable in that order.

Monitor is detected correctly and the optimal resolution is set (Raspbian) or you can change the res in the menu (OpenELEC). The /opt/vc/bin/tvservice is able to read monitor edid data. I tested the adapter using NEC 72VM 15" LCD. (1280x1024 60 Hz, 1024x768 60 Hz, 640x480 works) The adapter is based on Lontium LT8511A chip, but I was unable to get the specification for it. The D1 diode is getting very hot though. Most likely the adapter drives more than 200 mA. The standard RS Components 1.2 A USB power supply is able to provide enough power for the Raspberry Pi and the adapter. I"ll try to modify the adapter to connect external power to bypass D1.

The "Pi-View" was designed specifically for use with the Raspberry Pi. It does work although the small box gets warm and the video output isn"t great (slightly fuzzy text, smaller screen area even with overscan enabled) [17]

SCART adapters (SCART plugs with three RCA connectors in the back), will probably work when used with the yellow RCA plug connected to the Raspberry Pi"s RCA video output. Additionally using a splitter cable (3.5 mm jack plug on one end, and red-white RCA plugs on the other end) will probably work when plugged into the red and white (left and right audio channels) of the SCART adapter.

http://lightberry.eu it"s the first (I think), dedicated hardware for Raspberry Pi that can produce colorful effects behind your TV, when you watch movies or even pictures. It uses GPIO pins (not USB). It is easy to configure - you can even download configured system image from the producer website. Works perfectly :)

I have a couple of these displays. They are different from the Sainsmart, not the SSD1289 controller. It"s the ILI9327, the pin out is different from the other projects I have seen. It looks like it needs to be 16 bit parallel, and the notation on the board makes it hard for us NOOB"s to make the jump to know where to put the sinc signals.
