epdiy-eink-pc-monitor's Issues

Blocked with PC host app and EPDiy V6 PCB

Hi Amadeo,

Really nice project!
I compiled the client without problems. And now I have the issue that is not sending anything to the display from the PC host app.
This is my log for the PC host app:

Note: It was giving me an error before, since it needed this also to be installed pip install opencv-contrib-python
Any hint on what I'm doing wrong? The IDF epdiy client receives something, since the screen wakes up, but it shows only white pixels.
I could see only one frame of a quite distorted screen ;)

USB data transfer instead of wifi?

Hello, I'm wondering if it would be feasible to send the display data to the board over usb instead of wifi?

If so, would it require significant changes to the code?

Thanks!
