raspberry pi 3 tft display tutorial quotation

The TFT isn’t ‘plug & play’ with the Raspberry, a patch has to be applied to the kernel to be able to interface via SPI with the ST7735R controller chip on the TFT. Once working, the display will act as a framebuffer device.

As it takes over three hours to compile the kernel on the PI, I will show how to cross compile from another Linux PC. In my case, it is Ubuntu 12.10 running within VMWare on a Windows 7 Quad core PC. Kernel compile time is 15 mins.

-Get Kamal’s source which has the patch for ST7735R controller and the branch for the kernel that is used in 2013-02-09-wheezy-raspbian, which is 3.6.y;

-Copy config from the Raspberry Pi to the Ubuntu box using SCP. Replace ‘raspberrypi’ below with the IP address of your Raspberry Pi if hostname lookup fails.

If you are planning on displaying the console on the TFT, then enabling these options in .config will allow you to change the font size and rotate the display later on.

To enable parallel processing for a faster compile. If you have a dual core processor add -j 3 to the end of the command below. If you have quad core, add -j 6

The last step below is to SCP the files from from Ubuntu to the Raspberry Pi. If you have trouble SCPing into your Ubuntu box you may need to install open SSH on Ubuntu with sudo apt-get install openssh-server. This step also copies the files from my home folder ‘mark’… yours would be different.

If you build the st7735 driver pair as built-in, add these options to the end of the line in /boot/cmdline.txt. This will display the console on the TFT.

3.5 inch RPi LCD V3.0 HVGA 480X320. There is a XPT2046, 74HC04D, 74HC4040D, and 2 74HC4094D chips on the back. Is there a way to determine which driver I need to use in software?

I am not 100% convinced that the distribution given works with the LCD (the item I bought is dis-continued but the seller provided another item that has identical specifications - 3.5" IPS 15fps 480x320 resolution - but I suspect it has a slightly, or altogether different, controller.

[*]Is there any way I can extract some information of what driver has been used, or tried to use, for the TFT via that half working distribution? As far as I know, a GPIO/ SPI connection will not gather connected hardware information...

I bought a display off Amazon described as [ SainSmart 3.5" inch TFT LCD 240x320 RGB Pixels Touch Screen Display Monitor For Raspberry Pi for Model B & B+] and sold by: Sain Store. What I received is the 320x480 display you described. I am also trying to verify the model before I try to set it up.

It was working but was a bit too slow so, I Increased the speed After setting Everything back to normal the screen is not working properly. The display is fine , but the touch is not responding. Please help! Did I BROKE it ?

some jokes (dark jokes preferably, because I"m a horrible human being) displayed from JokeApi. I basically copied the example script and started from there.

Raspberry Pi is a Palm Size computer that comes in very handy when prototyping stuff that requires high computational power. It is being extensively used for IOT hardware development and robotics application and much more memory hunger applications. In most of the projects involving the Pi it would be extremely useful if the Pi had a display through which we can monitor the vitals of our project.

The pi itself has a HDMI output which can be directly connected to a Monitor, but in projects where space is a constrain we need smaller displays. So in this tutorial we will learn how we can interface the popular 3.5 inch Touch Screen TFT LCD screen from waveshare with Raspberry pi. At the end of this tutorial you will have a fully functional LCD display with touch screen on top of your Pi ready to be used for your future projects.

It is assumed that your Raspberry Pi is already flashed with an operating system and is able to connect to the internet. If not, follow the Getting started with Raspberry Pi tutorial before proceeding.

It is also assumed that you have access to the terminal window of your raspberry pi. In this tutorial we will be using Putty in SSH mode to connect to the Raspberry Pi. You can use any method but you should somehow be able to have access to your Pi’s terminal window.

Connecting your 3.5” TFT LCD screen with Raspberry pi is a cake walk. The LCD has a strip of female header pins which will fit snug into the male header pins. You just have to align the pins and press the LCD on top of the Pi to make the connection. Once fixed properly you Pi and LCD will look something like this below. Note that I have used a casing for my Pi so ignore the white box.

For people who are curious to know what these pins are! It is used to establish a SPI communication between the Raspberry Pi and LCD and also to power the LCD from the 5V and 3.3V pin of the raspberry Pi. Apart from that it also has some pins dedicated for the touch screen to work. Totally there are 26 pins, the symbol and description of the pins are shown below

Now, after connecting the LCD to PI, power the PI and you will see a blank white screen on the LCD. This is because there are no drivers installed on our PI to use the connected LCD. So let us open the terminal window of Pi and start making the necessary changes. Again, I am using putty to connect to my Pi you can use your convenient method.

Step 2: Navigate to Boot Options -> Desktop/CLI and select option B4 Desktop Autologin Desktop GUI, automatically logged in as ‘pi’ user as highlighted in below image. This will make the PI to login automatically from next boot without the user entering the password.

Step 3: Now again navigate to interfacing options and enable SPI as show in the image below. We have to enable the SPI interface because as we discussed the LCD and PI communicates through SPI protocol

Step 4: Click on this waveshare driver link to download the driver as a ZIP file. Then move the ZIP file to you PI OS. I used Filezilla to do this, but you can also use a pen drive and simple copy paste work.  Mine was placed in the path /home/pi.

Step 7: Now use the below command to restart your Pi. This will automatically end the terminal window. When the PI restarts you should notice the LCD display also showing the boot information and finally the desktop will appear as shown below.

Hope you understood the tutorial and were successful in interfacing your LCD with PI and got it working. If otherwise state your problem in the comment section below or use the forums for more technical quires.

In the previous article, I described the steps needed to install an LCD touchscreen on the Raspberry Pi. In this article, I will show you how to adjust the screen rotation of the LCD to landscape mode, and will show you how to calibrate the touchscreen pointer for optimal accuracy. Just follow the steps below to compete the process of setting up your Raspberry Pi LCD touchscreen:

1. First we need to change the setting for screen rotation in the /boot/cmdline.txt file. This setting is called fbtft_device.rotate=X. By default, this is set to X=0, which results in a portrait mode screen orientation. In order to switch the orientation to landscape mode, change fbtft_device.rotate=0 to fbtft_device.rotate=90. Enter sudo nano /boot/cmdline.txt at the command prompt. There should only be one line in this file. Go to the end of it and you will find the fbtft_device.rotate=X setting. Change the value from 0 to 90:

After the Pi finishes rebooting, you should notice that when you move your finger across the touch screen, the pointer should follow correctly in both axes. If you are using the Raspberry Pi 2 Model B, you will need to complete the calibration steps below before the pointer follows your finger correctly (and make sure that you have enabled startx to load automatically – see step 6 in this article).

You can rotate the screen 90 degrees (as we did in this tutorial) and the power connector will be at the bottom of the screen, but you can also rotate it 270 degrees so that the power connector is at the top of the screen. To do this, simply enter fbtft_device.rotate=270 in the /boot/cmdline.txt file. Then change the DISPLAY=:0 xinput --set-prop "ADS7846 Touchscreen" "Evdev Axis Inversion" 0 1 line in the /etc/X11/xinit/xinitrc file to DISPLAY=:0 xinput --set-prop "ADS7846 Touchscreen" "Evdev Axis Inversion" 1 0. All you need to do is switch the values of the 0 and 1 at the end of this line.

3. The calibration tool we will use is called ts_calibrate. We will also be using a program to check the results of the calibration called ts_test. In order to use ts_calibrate and ts_test, we must first set proper environmental variables. Enter export TSLIB_TSDEVICE=/dev/input/event0 into the command prompt, then enter export TSLIB_FBDEVICE=/dev/fb1:

4. Now we can use ts_calibrate. Enter ts_calibrate at the command prompt (make sure you are still in root mode) to run the ts_calibrate program. The program will consecutively display five crosses on different parts of the screen, which you need to touch with as much precision as possible:

Rather than plug your Raspberry Pi into a TV, or connect via SSH (or remote desktop connections via VNC or RDP), you might have opted to purchase a Raspberry Pi touchscreen display.

Straightforward to set up, the touchscreen display has so many possibilities. But if you"ve left yours gathering dust in a drawer, there"s no way you"re going to experience the full benefits of such a useful piece of kit.

The alternative is to get it out of the drawer, hook your touchscreen display to your Raspberry Pi, and reformat the microSD card. It"s time to work on a new project -- one of these ideas should pique your interest.

Let"s start with perhaps the most obvious option. The official Raspberry Pi touchscreen display is seven inches diagonal, making it an ideal size for a photo frame. For the best results, you"ll need a wireless connection (Ethernet cables look unsightly on a mantelpiece) as well as a Raspberry Pi-compatible battery pack.

Several options are available to create a Raspberry Pi photo frame, mostly using Python code. You might opt to script your own, pulling images from a pre-populated directory. Alternatively, take a look at our guide to making your own photo frame with beautiful images and inspiring quotes. It pulls content from two Reddit channels -- images from /r/EarthPorn and quotes from /r/ShowerThoughts -- and mixes them together.

Rather than wait for the 24th century, why not bring the slick user interface found in Star Trek: The Next Generation to your Raspberry Pi today? While you won"t be able to drive a dilithium crystal powered warp drive with it, you can certainly control your smart home.

In the example above, Belkin WeMo switches and a Nest thermostat are manipulated via the Raspberry Pi, touchscreen display, and the InControlHA system with Wemo and Nest plugins. ST:TNG magic comes from an implementation of the Library Computer Access and Retrieval System (LCARS) seen in 1980s/1990s Star Trek. Coder Toby Kurien has developed an LCARS user interface for the Pi that has uses beyond home automation.

Building a carputer has long been the holy grail of technology DIYers, and the Raspberry Pi makes it far more achievable than ever before. But for the carputer to really take shape, it needs a display -- and what better than a touchscreen interface?

https://www.anrdoezrs.net/links/7251228/type/dlg/sid/UUmuoUeUpU10530/https://www.youtube.com/supported_browsers?next_url=https%3A%2F%2Fwww.youtube.com%2Fwatch%3Fv%3Djpt3PiDNdEk

Setting up a Raspberry Pi carputer also requires a user interface, suitable power supply, as well as working connections to any additional hardware you employ. (This might include a mobile dongle and GPS for satnav, for instance.)

Now here is a unique use for the Pi and its touchscreen display. A compact, bench-based tool for controlling hardware on your bench (or kitchen or desk), this is a build with several purposes. It"s designed to help you get your home automation projects off the ground, but also includes support for a webcam to help you record your progress.

https://www.anrdoezrs.net/links/7251228/type/dlg/sid/UUmuoUeUpU10530/https://www.youtube.com/supported_browsers?next_url=https%3A%2F%2Fwww.youtube.com%2Fwatch%3Fv%3DaiE-mFCVgoo

The idea here is simple. With just a Raspberry Pi, a webcam, and a touchscreen display -- plus a thermal printer -- you can build a versatile photo booth!

https://www.anrdoezrs.net/links/7251228/type/dlg/sid/UUmuoUeUpU10530/https://www.youtube.com/supported_browsers?next_url=https%3A%2F%2Fwww.youtube.com%2Fwatch%3Fv%3DPWym4M7Dv7I

Various projects of this kind have sprung up. While the versions displayed above uses a thermal printer outputting a low-res image, you might prefer to employ a standard color photo printer. The wait will be longer, but the results better!

How about a smart mirror for your Raspberry Pi touchscreen display project? This is basically a mirror that not only shows your reflection, but also useful information. For instance, latest news and weather updates.

Naturally, a larger display would deliver the best results, but if you"re looking to get started with a smart mirror project, or develop your own from scratch, a Raspberry Pi combined with a touchscreen display is an excellent place to start.

https://www.anrdoezrs.net/links/7251228/type/dlg/sid/UUmuoUeUpU10530/https://www.youtube.com/supported_browsers?next_url=https%3A%2F%2Fwww.youtube.com%2Fwatch%3Fv%3DfkVBAcvbrjU

Many existing projects are underway, and we took the time to compile six of them into a single list for your perusal. Use this as inspiration, a starting point, or just use someone else"s code to build your own information-serving smart mirror.

Want to pump some banging "toons" out of your Raspberry Pi? We"ve looked at some internet radio projects in the past, but adding in a touchscreen display changes things considerably. For a start, it"s a lot easier to find the station you want to listen to!

This example uses a much smaller Adafruit touchscreen display for the Raspberry Pi. You can get suitable results from any compatible touchscreen, however.

https://www.anrdoezrs.net/links/7251228/type/dlg/sid/UUmuoUeUpU10530/https://www.youtube.com/supported_browsers?next_url=https%3A%2F%2Fwww.youtube.com%2Fwatch%3Fv%3DAO-1GEYHOdU

Alternatively, you might prefer the option to integrate your Raspberry Pi with your home audio setup. The build outlined below uses RuneAudio, a Bluetooth speaker, and your preferred audio HAT or shield.

https://www.anrdoezrs.net/links/7251228/type/dlg/sid/UUmuoUeUpU10530/https://www.youtube.com/supported_browsers?next_url=https%3A%2F%2Fwww.youtube.com%2Fwatch%3Fv%3DW-iTRMLJosc

Requiring the ProtoCentral HealthyPi HAT (a HAT is an expansion board for the Raspberry Pi) and the Windows-only Atmel software, this project results in a portable device to measure yours (or a patient"s) health.

With probes and electrodes attached, you"ll be able to observe and record thanks to visualization software on the Pi. Whether this is a system that can be adopted by the medical profession remains to be seen. We suspect it could turn out to be very useful in developing nations, or in the heart of infectious outbreaks.

We were impressed by this project over at Hackster.io, but note that there are many alternatives. Often these rely on compact LCD displays rather than the touchscreen solution.

Many home automation systems have been developed for, or ported to, the Raspberry Pi -- enough for their own list. Not all of these feature a touchscreen display, however.

One that does is the Makezine project below, that hooks up a Raspberry Pi running OpenHAB, an open source home automation system that can interface with hundreds of smart home products. Our own guide shows how you can use it to control some smart lighting. OpenHAB comes with several user interfaces. However, if they"re not your cup of tea, an LCARS UI theme is available.

Another great build, and the one we"re finishing on, is a Raspberry Pi-powered tablet computer. The idea is simple: place the Pi, the touchscreen display, and a rechargeable battery pack into a suitable case (more than likely 3D printed). You might opt to change the operating system; Raspbian Jessie with PIXEL (nor the previous desktop) isn"t really suitable as a touch-friendly interface. Happily, there are versions of Android available for the Raspberry Pi.

https://www.anrdoezrs.net/links/7251228/type/dlg/sid/UUmuoUeUpU10530/https://www.youtube.com/supported_browsers?next_url=https%3A%2F%2Fwww.youtube.com%2Fwatch%3Fv%3DGKwRCDt2vWo

This is one of those projects where the electronics and the UI are straightforward. It"s really the case that can pose problems, if you don"t own a 3D printer.

Is this not the cutest, little display for the Raspberry Pi? It features a 3.5" display with 480x320 16-bit color pixels and a resistive touch overlay so it is slightly larger than the Raspberry Pi board, which is perfect to cover it. The plate uses a high-speed SPI interface on the Pi and can use the mini display as a console, X window port, displaying images or video, etc. Best of all it plugs right on top nicely covering the Raspberry Pi board. Single power from Raspberry Pi is sufficient to operate the screen. As it uses the SPI and Power pin from Raspberry Pi"s GPIO, it is nicely stacked on the RPi board. We also carry the perfect case/enclosure for Raspberry Pi 3B/3B+ and also 4B to be used with this LCD.

One of the most awaited plugins for Volumio is finall here: the touchscreen plugin. With it you can easily show the gorgeous Volumio UI on any display, included the official Raspberry PI Display, available on our Shop. Let’s see how to easily achieve a fantastic touchscreen for your favourite music player in less than 10 minutes. This tutorial will explain how to connect the Raspberry PI display and enable the Volumio UI with the plugin.

Assuming you’ve already downloaded and flashed Volumio to your Raspberry PI (we suggest to use the newest  Raspberry PI 3), the first step is the wiring:First, let’s attach the ribbon cable going from the Raspberry PI Display to the PI itself. On the Raspberry PI Side, make sure the blue part of the ribbon cable is facing outwards. Your final goal should look like this:

You’ll have 4 coloured cables to connect too. They are 5v, GND, SDA and SCL. You can look at the below image to identify the proper pin on the Pi itself.

Notoriously, feeding your PI with an adequate Power Supply is mandatory to have a reliable system. That’s especially true when we connect a power-hungry device like the Raspberry PI Display. Luckily, there’s a way to understand if your PSU is good enough: just power on your pi and observe the screen, if you see a coloured square on the top-right side of the screen, it means that power to your PI is not enough. Don’t you see it? Then all is good.

The installation will last about 7 minutes, so wait patiently until you see “Installation Complete”. Now you can enable or disable the Display output to your likings.

I must admit that altough this display is not particularly brilliant when it comes to resolution and colour accuracy, it looks indeed very nice with Volumio’s UI. Also, usability is very good on the Raspberry PI 3 and the UI runs smoothly also with big libraries… So, folks, enjoy!

If you don’t have a Raspberry PI, or you’re simply looking for alternatives to the Official Raspberry PI Display, there are at least two extra options for you:

The Odroid display is not only a viable alternative, it also have several advantages over its PI counterpart:Since it takes power from USB and video signal from HDMI, it can be used virtually with any Computer with an HDMI output, not just the Odroid or the Raspberry PI.

UPDATE: Lot of time since I published the original article. The Odroid 7” does not seem to work properly with Raspberry PI (not tested with the Odroid). So, if you’re looking for a display for the Raspberry PI, get the official one.

The Waveshare 7” display has become rapidly a widely adopted display, thanks to its cheap price. However this particular touchscreen has shown several reliability issues (altough this seems fixed in latest models, thanks to a firmware update), it requires a particular touchscreen driver which is not always included in major distros and its colour reproduction is not the best.

Here we are folks! Hope you found this article helpful, you can share via comment below how you use your Volumio’s touchscreen setup and if there are other display alternatives!

※Price Increase NotificationThe TFT glass cell makers such as Tianma,Hanstar,BOE,Innolux has reduced or stopped the production of small and medium-sized tft glass cell from August-2020 due to the low profit and focus on the size of LCD TV,Tablet PC and Smart Phone .It results the glass cell price in the market is extremely high,and the same situation happens in IC industry.We deeply regret that rapidly rising costs for glass cell and controller IC necessitate our raising the price of tft display.We have made every attempt to avoid the increase, we could accept no profit from the beginning,but the price is going up frequently ,we"re now losing a lot of money. We have no choice if we want to survive. There is no certain answer for when the price would go back to the normal.We guess it will take at least 6 months until these glass cell and semiconductor manufacturing companies recover the production schedule. (Mar-03-2021)

All the accessories listed below tier pricing need to pay.We won"t deliver until you select. Power adaptor should be 5V/2000mA in output and center pin for positive voltage and the outer shield for negative voltage .The temperature for controller RTD2660 would increase during working.That"s normal phenomenon,not quality problem.
