I've been messing with e-paper today. This is driving the waveshare epaper hat with the USB port, reverse engineered from the windows tool.

@martijnbraam any pointers about the re process? (I wanted to do the same for Sony DPT epaper.)

@kmicu I didn't RE the panel, only the protocol the windows tool uses to talk to the IT8951 controller by dumping usb traffic with wireshark
