Python ST7789

Python library to control ST7789 TFT LCD displays.

Designed to work with the following Pimoroni ST7789 based SPI breakouts and Raspberry Pi HATs:

• 1.54" SPI Colour Square LCD (240x240) Breakout
• 1.3" SPI Colour Square LCD (240x240) Breakout
• 1.3" SPI Colour Round LCD (240x240) Breakout
• Display HAT Mini (2.0" 320x240 LCD)

Installation

First, make sure you have the following dependencies:

sudo apt update
sudo apt install python3-rpi.gpio python3-spidev python3-pip python3-pil python3-numpy

Install this library by running:

sudo pip3 install st7789

You will also need to make sure I2C and SPI are enabled in raspi-config (sudo raspi-config) - you can find them under Interface Options.

Examples

You can find some examples of use in the examples folder. Clone this repo with:

git clone https://github.com/pimoroni/st7789-python

and navigate into the examples folder with:

cd ~/st7789-python/examples/

You can pass most of them a parameter (square, rect, round, or dhmini) to specify the size/shape/rotation of screen, like this:

python3 shapes.py dhmini

Licensing & History

This library is a modification of a modification of code originally written by Tony DiCola for Adafruit Industries, and modified to work with the ST7735 by Clement Skau.

To create this ST7789 driver, it has been hard-forked from st7735-python which was originally modified by Pimoroni to include support for their 160x80 SPI LCD breakout.

Modifications include:

• PIL/Pillow has been removed from the underlying display driver to separate concerns- you should create your own PIL image and display it using display(image)
• width, height, rotation, invert, offset_left and offset_top parameters can be passed into __init__ for alternate displays
• Adafruit_GPIO has been replaced with RPi.GPIO and spidev to closely align with our other software (IE: Raspberry Pi only)
• Test fixtures have been added to keep this library stable
