I check - Correct display class for my Display is epd13in3b But with this module i get error: Error sending photo to display: display() missing 1 required positional argument: 'ryimage'

Any news? Can I help? Maybe give you ssh access to my RPi?

Sorry for the late response but I ordered this display but unfortunately my retailer won't deliver it any time soon.

I definitely need your help with this. AFAIK this screen is red-black-white, right? So can you try setting this in your ePiframe config to BW+Red, then restart with sudo systemctl restart ePiframe.service and let me know if it worked?

Thank you for fast answer... But my display is Black / White, 16 Grey Scales this

Strange, as the Waveshare code for this display here expects red image ryimage what is the cause of this error.

Can you try setting this BW+Red flag anyway and let me know? Maybe a different Waveshare class is needed here?

I think this is an issue with the correct class for your display. Let's wait for Waveshare to respond here: https://github.com/waveshareteam/e-Paper/issues/338

Waveshare does not respond. I search any information about Python examples. No one...

But examples on C is work fine. It's is possible work ePiframe with display controller IT8951 via C ?
