This is a collection of libraries and code that I use to drive the TTGO ESP32 ePaper 2.7inch display.
It has the display. An SD card, two microphones (!) and a speaker amp.
Out of it, I only have for mOS the libraries required to drive the EPD HERE alongside a ported EPDPAINT library HERE
All the libraries are based off the sample code provided by the sellers, which in turn, use the libraries made by Waveshare which you should totally take a look at.
If you wanna build the apps provided here it is easy. Clone this repository and navigate to either the epdclock or epdwaveshare_example folders and invoke mos build.
It should be able to build over the cloud as well
