What you built is super cool. If I would like to hack on an m5paper myself what ressources would you recommend that I start with to kick off a small project?
m5stack has several other example applications in their repo, but I learned a lot from reading their source code in the test app. Their code is quite sane and organized. You just need to be tolerant to their spelling from time to time, I figure English is not their first language (just like me).
