PlatformIO manages the ESP32 firmware for VanDaemon's 8-channel PWM LED dimmer. The firmware handles MQTT communication, WiFi provisioning via captive portal, and NVS state persistence. All firmware lives in hw/LEDDimmer/firmware/.
cd hw/LEDDimmer/firmware
# Build for 8-channel variant (default)
pio run -e 8ch
# Upload via USB
pio run -e 8ch -t upload
# Build 4-channel variant
pio run -e 4ch -t upload
# Start serial monitor at 115200 baud
pio device monitor -e 8ch
# Monitor with timestamp
pio device monitor -e 8ch --filter time
| Concept | Usage | Example |
|---|---|---|
| Environment | Build target variant | -e 8ch, -e 4ch, -e 8ch-ota |
| Upload | Flash firmware to device | pio run -e 8ch -t upload |
| Monitor | Serial debugging | pio device monitor |
| Clean | Remove build artifacts | pio run -t clean |
| OTA | Over-the-air updates | -e 8ch-ota environment |
When: Making firmware changes
# Clean, build, upload, then monitor
pio run -e 8ch -t clean && pio run -e 8ch -t upload && pio device monitor -e 8ch
When: Device deployed and accessible via WiFi
# Build and upload via OTA (requires device IP in platformio.ini)
pio run -e 8ch-ota -t upload
When: Updating SPIFFS/LittleFS data
pio run -e 8ch -t uploadfs
// PWM Outputs (8 channels)
GPIO 25, 26, 27, 14, 4, 5, 18, 19
// Status LED (WS2812)
GPIO 16
// Buttons
GPIO 32 (Button 1), GPIO 33 (Button 2)
The firmware publishes to topics under vandaemon/leddimmer/{deviceId}/:
status - online/offlineconfig - device configuration JSONchannel/{N}/state - current brightness (0-255)Subscribes to channel/{N}/set for brightness commands.
