Is there a circuitPython library to interface with the Adafr

by centralHarlem on Tue Oct 19, 2021 8:11 pm

I recently got the Adafruit eInk Feather Friend, planning to use it with a 4.2" eInk screen. Only now do I notice the the libraries provided by Adafruit appear to be Arduino-only (https://github.com/adafruit/Adafruit_EPD). Is there a way to use this "Feather Friend" with circuit python?

What about https://github.com/adafruit/Adafruit_CircuitPython_EPD. You should get the mpy from the bundle.

I think you are seeing something that I am not seeing. Can you be more explicit?

Will that library not work with it?

What exact screen are you using? The screens have a driver chip on them that requires a software library and the way the screen is hooked up can impact the initialization sequence as well.

The EInk friend itself doesn't need a driver for the display because it only provides the ribbon cable connection.

Tannewt — the screen I am using is a PiMoroni inkyWhat, specifically this variant: https://shop.pimoroni.com/products/inky ... 4020436051

I had figured to wire it through the eInk feather friend (https://www.adafruit.com/product/4446)

Dave — I don't see an MPY there.

Yeah, you'd grab that out of the appropriate bundle (that matches your version of CP): https://circuitpython.org/libraries

Ah, you may want to look into their Python driver then. It should give clues about what driver chip is used. We have libraries for most of the common ones already. They may require tweaks though for the different display.
