…support The initial C6L port (meshcore-dev#1578) had several incorrect hardware configurations. Fixes verified against the Meshtastic variant (meshtastic/firmware variants/ esp32c6/m5stack_unitc6l/variant.h) and tested on actual hardware. Pin corrections: - I2C: SDA=10, SCL=8 (was SDA=16, SCL=17) - TCXO voltage: 3.0V (was 1.8V) - TX indicator: NeoPixel on GPIO 2 (was P_LORA_TX_LED=15) - Remove SX126X_RXEN=5 (LNA enable is on PI4IO expander P5, not GPIO 5) - Add ARDUINO_USB_CDC_ON_BOOT and ARDUINO_USB_MODE for USB serial Add PI4IO I2C GPIO expander support (addr 0x43): - P0: Button input (active low) - P5: LNA Enable output - P6: RF Switch output - P7: LoRa Reset output - Proper initialization sequence for RF control Fix ESP32-C6 BLE companion build: - Add missing #include <esp_mac.h> for esp_efuse_mac_get_default() Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
