Need an expert opinion:
I have a SK9822 LED-strip (288 LEDs) controlled by FastLED running on an Espressiv ESP32 Dev Kit. The strip is powered from an external PSU with 20 A, connected with common ground to the ESP32. On the data pin I included an 410 Ohm resistor. Everything works fine, except:
There are 7 LEDs at the end of the strip, which do not respond properly. I am unable to control them with normal sketch-code. Nevertheless some of them start to lite up in full white randomly and don’t turn off until I power off the whole system.
Are they simply defect, or is there something I could do about it to fix it?
Thanks for any help!
