I am unable to successfully get my GW6205 pixels controlled properly using a Node ESP32 MCU. I have even tried with SN74HCT245 level shifter. I am not sure what the problem is and have tried several different GPIO. For a sample string of 20 pixels, simply trying to blink an individual pixel is unresponsive and sometimes will display completely different color on the wrong pixel. I'm happy to provide any further information to help figure out how to get this working. I will also say that these pixels run off 24V DC power. I have a separate power supply for the pixel string and then have the data coming in from the esp32, sharing common ground.

Appreciate the help in advance.

For laughs, try GW6205_400 as the led type - also make sure you’re using the most recent version of FastLED (3.2.6) as there have been esp32 fixes to the clock less code.

Tried the GW6205_400 to no avail. I have also updated the FastLED library to the latest 3.2.6. I am using the example sketch from FastLED "Blink" for my testing.

I have the Adafruit ESP32 feather as well as the Node-MCU ESP32. Have tried both with and without the level shifter and various GPIO pins still to no avail.

I found this video https://www.youtube.com/watch?v=ykwkaPpUBZY on youtube where they are using the FastLED library with another type of mcu and seem to get it working with the GW6205.
