Goal

Drive the initial Ground Station kiosk menu using final RC channels sent by GX12 over the dedicated UART.

Confirmed safety gate

  • CH5/AUX1 is arm state (zero-based UART channel index 4).
  • -1024 is disarmed.
  • >=0 is armed.
  • Input is ignored while armed, and missing/invalid arm input fails closed.

Input model

  • right stick: four-way navigation;
  • one explicitly configured button/switch: select/confirm;
  • inputs are accepted only while the aircraft is confirmed disarmed.

Design constraints

  • Use a debounced directional state machine: one initial step, then controlled repeat while held.
  • Do not bind to fixed channel numbers in code; use /etc/groundstation/config.yml.
  • Initial config assumes Mode-2 right stick on CH1/CH2 but remains configurable.
  • Confirm defaults disabled (confirm_index: -1) until Piotr chooses a physical control.
  • Menu activity must never alter the primary RC stream or Betaflight controls.

Acceptance

A simple menu with at least two visible entries can move up/down/left/right and select once per confirm press while disarmed. The same input does nothing when armed.

Deferred by #20. Radio-stick kiosk navigation is intentionally skipped until resilient telemetry and adaptive-link core are implemented.
