I have just received a couple of FireBeetle ESP32 modules (FireBeetle ESP32 IOT Microcontroller (Supports Wi-Fi & Bluetooth) – Pimoroni) and I have a problem with the RGB LED.
When the module arrived, it was programmed in a way that pressing the button on the side (input 27) caused the RGB LED to cycle through three colours, so I know it is working.
I have tried to program it with the RGB example on the product Wiki page (section 7.7 of FireBeetle_Board_ESP32_E_SKU_DFR0654-DFRobot ), but it just lights up all three LEDs to give white.
Has anyone else got this working? If so, can you share which LED library you used, and how you initialised the LED?
