All peripherals live behind board::* modules in src/board/, so demos in main.cpp only deal with framebuffers and logic.

Current demo

src/main.cpp — wireframe 3D cube with a scrolling marquee, orientation driven by the IMU through a complementary filter. Tilt the board, the cube tilts with it.

Build & flash

Requires PlatformIO.

pio run -t upload      # build + flash
pio device monitor     # serial @ 115200

Board target and flags are in platformio.ini.

Status

Sandbox repo. Things change, demos get replaced, APIs are not stable.
