I have an ESPRESSIF ESP32-WROOM-32D and would like to control a SK9822 (APA102) with it.
Which pins do I have to use for this?
With luck I used pin 23 for data and pin 18 for Clk.
This works with short strips (approx. 50 LEDs), with long strips (approx. 250 LEDs) everything stays dark…
My pins on the ESP32 look like the one shown in the appendix.
Thanks in advance
