Introduction

Port of display drivers from https://github.com/adafruit/micropython-adafruit-rgb-display to Adafruit CircuitPython for use on Adafruit's SAMD21-based and other CircuitPython boards.

Note

This driver currently won't work on micropython.org firmware, instead you want the micropython-adafruit-rgb-display driver linked above!

This CircuitPython driver currently supports displays that use the following display-driver chips: HX8353, HX8357, ILI9341, S6D02A1, ST7789, SSD1331, SSD1351, and ST7735.

Dependencies

This driver depends on:

• Adafruit CircuitPython
• Bus Device

Please ensure all dependencies are available on the CircuitPython filesystem. This is easily achieved by downloading the Adafruit library and driver bundle.

For improved performance consider installing numpy.

Installing from PyPI

On supported GNU/Linux systems like the Raspberry Pi, you can install the driver locally from PyPI. To install for current user:

pip3 install adafruit-circuitpython-rgb-display

To install system-wide (this may be required in some cases):

sudo pip3 install adafruit-circuitpython-rgb-display

To install in a virtual environment in your current project:

mkdir project-name && cd project-name
python3 -m venv .env
source .env/bin/activate
pip3 install adafruit-circuitpython-rgb-display

Usage Example

import time
import busio
import digitalio
from board import SCK, MOSI, MISO, D2, D3

from adafruit_rgb_display import color565
import adafruit_rgb_display.ili9341 as ili9341


# Configuration for CS and DC pins:
CS_PIN = D2
DC_PIN = D3

# Setup SPI bus using hardware SPI:
spi = busio.SPI(clock=SCK, MOSI=MOSI, MISO=MISO)

# Create the ILI9341 display:
display = ili9341.ILI9341(spi, cs=digitalio.DigitalInOut(CS_PIN),
                          dc=digitalio.DigitalInOut(DC_PIN))

# Main loop:
while True:
    # Clear the display
    display.fill(0)
    # Draw a red pixel in the center.
    display.pixel(120, 160, color565(255, 0, 0))
    # Pause 2 seconds.
    time.sleep(2)
    # Clear the screen blue.
    display.fill(color565(0, 0, 255))
    # Pause 2 seconds.
    time.sleep(2)
