Official Description & Notes
I've been busy playing with another ESP32 based e-Paper display. Once again we're sponsored by PCBWay - https://www.PCBWay.com/?from=atomic
There are some interesting aspects to this project:
We're using deep sleep to save on battery - check out my recent video on this subject for a deep dive: https://youtu.be/YOjgZUg_skU
We're also using an SD Card in SPI mode using a few of the spare GPIO pins on the board - we've covered this previously in this video: https://youtu.be/bVru6M862HY
Parsing, layout out and rendering ePub files is pretty interesting. It's a good challenge to try and get this working nicely on embedded devices like the ESP32.
