You will need to enter them in the lib_tft24T.py file. Once done, you will presented with some calibration figures, make a note of them. Run the following through SSH.ДЇollow the instructions on your SSH terminal and you will need your stylus pen for this рџ™‚ Now that you have wired your ili9341 SPI TouchScreen LCD to a Raspberry Pi, you need to calibrate it. To use the ili9341 according to how we have shown, download our modified code here.Д«rian Lavery has also written some calibration code to help getting the exact postion of where you have your stylus down. Reboot your Pi and check whether you see SPI1 in /dev/Д«rian Lavery code works with only SPI0 and not SPI1. This will only enable one CS line you can have up to 3 on the SPI1 bus. SPI1 is disabled by default and to enable it, enter the following in your /boot/config.txt However, to make this simple, we are using jumper cables, and it is not easy to connect two jumper cables to the same SPI_SCLK pin without getting our soldering iron out! So we decided to connect the Touch part to SPI1. SPI0 can support 2 devices so we can also connect the touch part to SPI0.

The Raspberry Pi has 2 SPI Bus, SPI0 and SPI1. First of all finish wiring the ili9341 SPI TouchScreen LCD to the Raspberry Pi according to the following table: ili9341 Pin Now that you have a working display, it is time to get the touchscreen to work. If it runs successfully, you will see this on your SSH terminal:ДЄnd you should see this on the ili9341 SPI TouchScreen LCD: Try searching for the errors you get Google is your friend рџ™‚ If you get an error, check if you have successfully installed the prerequisites. Extract the archive in your user space on the Pi and run the following command:

#HOW TO USE RETROPIE ON RASPBERRY PI 3 3.5 INCH LCD DISPLAY INSTALL#

Once you have wired the ili9341 LCD to the Pi and have install all the prerequisites, try to run the following code. Sudo apt-get install python-dev python3-dev To be able to use the python driver, there is a few prerequisites that you need to install on your Pi.

If you do try it, please do let us know how you got on.

We used the driver written by Brian Lavery which can be downloaded on his github.ДЄdafruit also has a python driver but we did not try it. In our case, we did not have the time to do, so we cheated a bit.

The datasheet for the ili9341 SPI LCD is readily available and you are welcome to use it to create your python driver. ili9341 SPI Raspberry Pi Wiring (Display Only)ДЇor a start, connect the ili9341 SPI TouchScreen LCD to a Raspberry Pi as follows just to get the display: Install the latest Raspbian and power the Pi with SSH and Wifi enabled. We used a Raspberry Pi Zero W in this tutorial. A comparison between the SPI and the 8-bit Parallel one is shown below: Make sure that you get the SPI version and not the 8-bit parallel one. To get started, you need an SPI LCD screen.

Please bear in mind that we are not showing how to display the full Raspbian GUI on the LCD but rather running a Python program and display on the LCD while the program is running! In this post, we are going to show you how to connect the ili9341 SPI TouchScreen LCD to a Raspberry Pi in Python. You can either use a character LCD but you are limited to characters. Connecting to a big monitor can be a bit of an overkill specially if you want to keep your project compact. For many Raspberry Pi projects, it may be convenient to have a small display to show valuable information.
