Nodemcu & ws2812 Problems

Issues
1

hi @ all.

i’ve got a strange problem. i just assempbled my nodemcu and a ws2812b ledstripe.
when i power it up, just a few leds are power up and light in red.
at first i thought the ledstripe is broken.
but when i “activate” palette 2, all other leds went on and i’m able to change their color.
it seems, the first leds only change, when i change palette1 and all the others belong to palette2.

setting up any effects only changes the leds that first came up.

the stripe contains 66 leds and i use an external powersupply with 5V/5A. the data is connected to D2.
the data cable is about 5cm long and i even tested the workaround via a “sacrificcial led”.

any ideas?

thanks in advance.

damn! it works and of course is was my fault.
just used the wrong image.
after re-flashing & resetting everything works fine.

now i only have to find out hwo to set a start animation.

Awesome you got it to work!
To set a start animation, just select the desired Color & Effect and save it to a preset slot (in the Favorites tab). Then set the slot number as boot preset in LED settings :slight_smile:
