Release v1.0.0

FlightSoftware-Mastodonte — Release v1.0.0

This version delivers a complete and functional embedded flight sequencer for the Mastodonte rocket, running on the YD-RP2040 avionics board (RP2040-based). It ensures the execution of all mission-critical phases with state-based logic, hardware interfacing, and onboard logging.

Main Features

• Deterministic flight state machine:
  • States: PRE_FLIGHT, PYRO_RDY, ASCEND, WINDOW, DEPLOY_ALGO, DEPLOY_TIMER, DESCEND, TOUCHDOWN, ERROR_SEQ
• Visual and audible feedback through WS2812 RGB LED and buzzer
• Event-triggered transitions based on GPIO interrupts (RBF, JACK, sensors)
• Timestamped logging system with LittleFS flash storage
• Manual log dump and erase via GP24 user button
• Motor control via DRV8872 drivers (grouped activation with timeout)
• Safety checks on boot (temperature, battery, flash capacity)

Usage Notes

• Logs can be dumped or cleared at startup by interacting with the GP24 button:
  • Short press: Serial dump at 115200 baud
  • Long press (>5s): Log erase
• Deployment logic supports both timer-based and sensor-triggered triggering
• Flash writing is deferred using a background task or buffered mode

Dependencies

• Arduino (Earle Philhower RP2040 core)
• PlatformIO build system
• External libraries: Adafruit NeoPixel

Known Limitations

• No dual-core support implemented at this stage
• Logging is disabled if flash usage exceeds 95% or system enters ERROR_SEQ
