Two new documents to drive the Sprint 1 approval cycle when the user
reviews in the morning. NO firmware code touched -- this is planning
material only, per brief rule #1 "Antes de cada sprint, me presentas
plan detallado y esperas mi OK. No improvises features."
docs/sprint-1-plan.md
- Sprint 1 objective (firmware boot + STANDBY + Modbus slave +
NMEA 2000 consume of PGN 127250/127251 + watchdog).
- 4 explicit technical decisions awaiting the user's go/no-go:
2.1 Framework: Arduino-as-ESP-IDF-component (recommended)
2.2 New libraries: NMEA2000-library, NMEA2000_esp32, eModbus
(asked per brief rule #4 "No agregues dependencias sin
preguntarme")
2.3 FreeRTOS core/priority mapping (PID isolated on Core 1)
2.4 Logging: ESP_LOG via UART0
- 7-phase breakdown over 3-4 weeks (mirrors brief's Sprint 1 scope).
- Acceptance criteria, risks, and the inputs needed from the user
before kickoff (hardware availability, schematic, NMEA 2000 bus).
docs/firmware-libraries-research.md
- Detailed rationale for each library choice with comparison tables.
- Pinout / hardware references aligned with the existing
firmware/ar_autopilot_v1/src/hal/pinout.h.
- Draft platformio.ini outline (NOT yet written to the firmware
directory -- needs user OK first).
- All external sources cited for traceability.
