Hi!

I started packaging the demo app. Here are already packages for depends, RPi.GPIO and spidev. Converting the zip into a package will take more time.

Well, I made a first attempt.

I think it's going in the right direction, but there is an unexpected problem. It also needs the pillow package: https://pypi.org/project/Pillow/. When I install it, the waveshare-demo throws an exception, and debugging led me to the conclusion that the .so files in the pillow aarch64 wheel are built against GNU libc, which isn't 100% compatible with openwrt. So you probably have to add building pillow from source. Debug info:

That is regarding the LCD.

The fan seems to work now, using the fan demo app. However I'm not 100% sure if it wasn't already working before.

The fan seems to work now, using the fan demo app. However I'm not 100% sure if it wasn't already working before.

Hmm I may be getting stupid, I didn't realize that an LCD under linux is probably going to be seen as a display and perhaps you may need X. Let me test and I'll see what's going to happen.

I think I'll use ubuntu on this device, it's too much work otherwise. We'll skip this.
