The neopixeis are powered by a power source with 30 A at 5V, and the grounds of ESP32, the strip, and the power source are connected
Yes my strip are RGBW
I use the delay(1) and improved but stills flicker e tried delay(5) and stills...I think it flickers because the pin like ESP8622 it maybe only works fine on especific port...but ESP dev kits has many varients and I cannot find mine because I want to use RX pin like ESP8622
I already try with RX0 and stills flicker
I tested the code and strip with an ESP8622 and no flicker
Someone already has ESP32 with SK6812 strip working
??
Yes, I do, rgbw also. You may need a level converter. did you get to try one? Did you try just setting it to five pixels?
