ESP32 Forum

I have an ESP32-S2-Saola-1 development board and I am trying to get the WS2812 led going. I was able to successfully build and test the "Helloworld" example project to load and run. So I moved onto the 'rmt/LED_STRIP' project.

I duplicated the LED_STRIP project, ran 'idf.py set-target esp32s2' succesfully. Then i ran 'idf.py menuconfig' and set the 'RMT_TX_GPIO = 18' and the 'Number of LEDS in a strip = 1'. I was able to build and flash the project and see the starting log information print in the monitor.

When I run the project the WS2812 led just stays off, and I don't see any colors. Is there somthing I am missing? Is this the appropriate example to test the WS2812 on the board?

Thanks,
Terry

I figured it out. I have v1.1 of the Saola board which has the RGB led pin mapped to pin 17 not 18 like v1.2. FYI, The only documentation I can find is for the v1.2 board.

Did you get your code to work? I have V1.2, so the example code should just work for me?
