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)

Features

• cool splashscreen and exit screen :-)
• battery consumption saving
  • turn off display after 5 seconds of inactivity
  • use cpu light sleep mode cycles (100ms) in main loop
  • turn off unused subcomponents (WI-FI chip)
  • set CPU frequency to 20MHz
  • activate by:
    • touching display
    • short press button
    • "tilt up" maneuver (can be turn off on settings screen)
• vibration can be disabled in settings screen

• for full list of features, see changelog.txt
• synchronize date & time with computer during compile/upload

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 )

Future features :-)

• conection vith phone via BT (require app for android)
  • SMS notification icon
  • missed call icon
  • other notifications icon
  • show who's calling
    • ability to reject call
  • show SMS content (and mark as read in phone)
