I did something similar for my daily calendar. I don't have a writeup of the actual device, but here's the firmware that generates the calendar image:

It's a really fun project, but I wish these Waveshare displays had more open firmware. I didn't really manage to get the ESP32 to talk to the display (or even to connect to it, as I don't have the right adapter), so I used their sample code with its weird API and I'm sending an image straight to the ESP32, rather than have the ESP32 pull it from an HTTP server, as I wanted.

check out our FW, it's open source and will work with Waveshare <> ESP32. currently running on thousands of devices: https://github.com/usetrmnl/firmware/

I was wanting to, but doesn't that only work with your PCB (pinouts, etc) and specific e-ink display? If not, I have lots of displays I want to drive!
