Support e-Ink Waveshare 2.13" model G (silver Sticker) #105

Opalinus commented 10 months ago

Description

added minimal support of e-Ink Waveshare 2.13" model G. Only b/w supported although the display also supports yellow and red.

Motivation and Context

Original files pulled from https://github.com/waveshareteam/e-Paper/ to fix this issue

How Has This Been Tested?

This does not work when using AUTO mode but only MANU mode. I tried setting ui.fps = 0.00016 and = 1 in AUTO mode, but the display still refreshed multiple times per second.

So this is basically unusable until I understand what is going on. I might open another issue...

I would love some help to understand why my display is flashing so often. I can contribute a video/gif

I've tried to test this on my rig as I have the same requirement and see the following output:

Can be resolved by adding the import to pwnagotchi/ui/hw/init.py

Thank you @Jubblin for testing and the very helpful log. I have added the changes and it should work know.

And yes I have messed up the commit, I'm still new to git.

Am seeing the same issue on my device, have ordered up a black and white screen to compare

Thanks for confirming. I did also run both waveshare examples in python and C and it looked the same.

I also noticed this model does not support partial refresh (its mentioned in the datasheets but not implemented)
