simple OS for LillyGO T-Watch V3

cyberWatch

Simple OS for LILYGO® T-WATCH-2020 V3, based on Xinyuan-LilyGO /TTGO_TWatch_Library.

Free time project to create lightweight and simple OS for smartwatch, with only necessary small functionality (to keep it simple and effective). With strong DIY cyberpunk motivation (don't want to support and pay money to big corporations). And with cool 80' cyberpunk retro design!
