; AR-Autopilot v1 -- firmware build configuration
; =============================================================================
;
; Target hardware: AR-NMEA-IO v1.0 (ESP32-DOWD-V3, dual-core 240 MHz)
; Build system:    PlatformIO 6.1+
; Framework:       arduino (on ESP32 -- includes FreeRTOS, full Espressif stack)
;
; This file is the single source of truth for the firmware build. Versions of
; the platform, framework packages, and library dependencies are pinned for
; reproducibility.
;
; Tasks (from the project root):
;
;   .venv/Scripts/pio.exe run                 # compile (default env: esp32-dev)
;   .venv/Scripts/pio.exe run -e esp32-debug  # compile with extra debug flags
;   .venv/Scripts/pio.exe run -e native       # build host-side Unity tests
;   .venv/Scripts/pio.exe test -e native      # run host-side Unity tests
;   .venv/Scripts/pio.exe check               # static analysis (cppcheck)
;   .venv/Scripts/pio.exe run -t upload       # flash (needs the board plugged in)
