I'm working on an IoT prototype based on Arduino. Ultimately I’m looking to send an image to an ePaper display through a local network (or over the internet). To successfully create this code you will need an IT8951 board or be familiar with it. The goal is to use an ESP32 board to receive the image wirelessly from LAN (ideally from POST from a webserver) and pass it on to an IT8951...
