I recently purchased this display for a project Im working on, they provide Arduino code to initialize the display and write bitmaps, which works, however I am unable to manage to port the sketch to Python or circuitpython.

My first attempt was to transpose to python on a rpi-zw, but I was unable to get the display functioning. I then went out and grabbed a Grand Central and loaded the Arduino sketch which worked. Now going to CircuitPython I am unable to get any further and was hoping that someone could help in adding support.

Simply looking over what is needed to modify an existing (like ssd1322) library depends on displayio which does not support multiple chip select pins as far as I'm seeing. So I felt that the appropriate place for this is here.

Also, there are others that have worked on this for the u8g8 libraries for Arduino:

Support for SSD1320
Large SSD1320Z*2 Based OLED Help Needed
