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.
This driver depends on the Adafruit CircuitPython BusDevice module being installed on the board too: https://github.com/adafruit/Adafruit_MicroPython_BusDevice
Note that this driver currently won't work on micropython.org firmware, instead you want the micropython-adafruit-rgb-display driver linked above!
