I have problems with flicker Apa102 LEDs with connected on a NodeMCU. The LEDs flicker not allways, but by different colours and brightness.
But first my hardware on the TV:
-Raspberry Pi 2
On the TV I have no problems.
Now to the NodeMCU and Apa102 LEDs:
I read this great tutorial to config my NodeMCU and Hyperion on the TV.
For the NodeMCU I use the software from tpmodding. You can find this in post 129 on page 9.
What I have already tried:
-reduced the lenghts of clock and data cable (80 mm)
-used a shielded cable for clock and data (LAN CAT 7)
-tested different baudrates ( 250000, 50000000 and 1000000)
But all this get no improvement.
Have you any ideas?
