ESP-IDF Compilation Service for ESP32 targets.
|
|
|
|
Replaces arduino-cli for ESP32/ESP32-C3 compilation. User Arduino sketches
|
|
are compiled using ESP-IDF (with optional Arduino-as-component) to produce
|
|
firmware that boots reliably in the lcgamboa QEMU fork.
|
|
|
|
The key difference vs arduino-cli: ESP-IDF gives control over bootloader,
|
|
sdkconfig, and flash mapping — all of which must be QEMU-compatible.
|
|
|
|
Two compilation modes:
|
|
1. Arduino-as-component: Full Arduino API (WiFi.h, WebServer.h, etc.)
|
|
compiled through idf.py. Requires ARDUINO_ESP32_PATH env var.
|
|
2. Pure ESP-IDF: Translates common Arduino patterns to ESP-IDF C APIs.
|
|
Fallback when Arduino component is not installed.
