Steps to reproduce.

~/esp/master/esp-idf (master)$ cd ./examples/get-started/blink/

More Information.

If I change color in main/blink_example_main.c

-led_strip_set_pixel(led_strip, 0, 16, 16, 16);
+led_strip_set_pixel(led_strip, 0, 16, 0, 0);

it starts to work as expected. It works with (16,0,0), (0,16,0), (0,0,16), but it doesn't work with (16,16,0) or (16,16,16).

I can't reproduce the issue on my ESP32-C6-DevKitC-1 V1.1 board. I watched your video, maybe your LED (WS2812) is broken somehow?

dmage commented 2 weeks ago

I hoped that a new board shouldn't have such issues, but it may well be the case. Yellow (15,15,0) spontaneously turns off after 5-10 seconds. Red immediately turns off for values 23 and more. Green and blue work much better, yet still weird glitches happen - occasionally it doesn't react on updates or turns off instead of changing color.
