A couple of weeks I got a paperd.ink display. I must confess I bought it on impulse. I am a sucker for EInk tech. But upon receiving it I realized I just don’t know how to code for it. So I decided to embark on a masochistic journey through the world of embedded programming, mainly by reading the source code of the few examples available.
As I was going through that, I thought it would be fruitful for me and potentially others to annotate, as best as I can, the different components of the code that make up a program for this display/board.
