FireBeetle ESP32 RGB LED Problem

Support
#1

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?

I’m having the same problem, did you ever figure it out?

Yes, I did. But I can’t remember the details, and I don’t have that computer to hand right now.

I know it was a very simple change, and I think it was removing the line that set the internal LED pin as an output.

I will check my code tomorrow, and update you.

Sweet! If you could let me know the library too that’d be super helpful. Or just post code.
