The SC01 Plus now acts as a composite USB device (CDC serial + HID keyboard).
Touch gestures on the screen send keystrokes to the computer:
- Swipe up/down: arrow keys
- Swipe right: Enter
- Swipe left: Shift+Tab (change mode in Claude Code)
- Double-tap logo: Ctrl+Space (voice mode)
- Tap and hold: Space (held while touching)
Gesture-to-key mapping is defined as a simple config table in hid.cpp.
Touch detection uses a state machine with configurable thresholds in touch.cpp.
Switches to TinyUSB composite mode (ARDUINO_USB_MODE=0). Flashing now
requires flash.sh which handles the DTR/RTS bootloader reset.
