I am having an issue with the ESP32-PoE-ISO by Olimex and 6 strips of 420 WS2815 addressable LEDs.
I have these strips hooked up to a 12v 50amp power supply and they are connected to pins 2,3,32,33,14,15. I am using the FastLED library to control them and the esp32 is running off of PoE. it is grounded straight to each strip.
The issue I am having is flickering of strips, and when pin 2 or/and 4 are connected plus any other pin, pins 2 and 4 go crazy (flashing random colors, etc.) but when just 2 or/and 4 are connected I usually get mostly good results with just some flickering.
Things I've tried...
I have tried several several things now...
- I've added the lines "#FASTLED_ALLOW_INTERRUPTS 0" and "#FASTLED_INTERRUPT_RETRY_COUNT 0"
- Completely removing all Ethernet code
- Updating each strip separately
- Logic Level Conversion
- With and Without capacitor on power line and resistor on data line
