cyberWatch

Simple OS for LILYGO® T-WATCH-2020 V3, based on Xinyuan-LilyGO /TTGO_TWatch_Library. Partially support for LILYGO® T-WATCH-2020 V2

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!

Installation

download and install VS Code and PlatformIO (or any other C/C++ IDE)
- (use complex IDE; this project is too large fro Arduino IDE)
~~clone~~ download this repository
add TTGO library to the project, following instructions in library's readme
connect LillyGo T_Watch device via USB
compile and upload via your favorite IDE
have a fun!
screen is autolocked (prevention of random touch) - if there is a lock icon, press crown (button) to unlock it!

Code quality & standards

Misra C++ standards (98% and still improving)

Known bugs

"tilt up" maneuver sometimes doesn't activate display (maybe will be solved by tuning BMA423 sensor)
activated by touch (when display is off) also do "touch event" on component on touch coords (e.g. when current screen is watch settings, activation also can activated display on, when display activation touch is at left top corner of display )
