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