Ws2812b doesn´t light up

[Psyobilin]

Hi!
No matter what I try, my strip doesn´t light up.

That´s what I´ve edited in platformio.ini
[env:s2_mini_WS281x_RGB]
build_flags = -DNEOPIXEL_RGB -DDATA_PIN=16 ${env.build_flags} -DSECOND_SEGMENT_START_INDEX=142 -DSECOND_SEGMENT_DATA_PIN=33
custom_prog_version = esp32_s2_mini_WS281x_RGB

Here´s the log:

For testing purposes I only have a small piece of LED Strip attached, but even this won´t light up. Please can anyone point me to the right direction?

Hi
Wrong speed and maybe something else too. Did you check the communication? https://github.com/awawa-dev/HyperSPI?tab=readme-ov-file#performancedebug-output

Thanks for your fast reply! Only result I get is [screen is terminating] ?!?

yes but you were using wrong speed. Check cabling and connect ground directly to esp32-s2, not level shifter (but it should be a path to it).

[Psyobilin]

Can it be that there is a problem using HyperHDR as container in docker?

[awawa-dev]

I dont know

[Psyobilin]

What did you mean with wrong speed?

[Psyobilin]

I think I have it... looks like I had a faulty solder on my GND. Now it works!!!!!! Thanks a lot!
