Micropython SSD1675A driver
This driver is initially trying to support Mike Rankin's ESP32 E-Paper board (thanks for the prototype Mike!) under Micropython. However the intent is to provide a useful Micropython driver for any SSD1675a-powered display.
Drewler's Arduino driver was very helpful, especially for initialization.
Peter Hinch's epaper library was another useful reference.
