Does anyone know what kind of IC is used in the govee H619?
Govee RGBIC LED Strip Lights With Protective Coating
It doesn’t say on the IC and I can’t seem to control the strip with any of the LED types in WLED. Whichever one I choose, the strip does either nothing, goes full white or starts flickering.
I’m using a ESP32.
Ok so to answer my own question. The IC is a WS281x type. I just had to use a level shifter to get the led strip to work. It did only work when I used GPIO 2 on the ESP32 though and I still have some flickering.
What shifter are you using?
Make sure you have no floating inputs and a bypass capacitor.
You should be able to use any valid GPIO on the ESP32, try #4,13, or 16.
Make sure you change your strip config in WLED to match your GPIO choice.
What ESP32 are you using?
The problem has been solved in the other thread: 24v strip: 12v works, changing adapter to 24v fails - Hardware - WLED
At the time I had the problem with two different 24v strips, but the solution ended up being the same.
