Start with our suggested settings above, but if those don't work you'll need to play around with them a bit.
LED Type
There are lots of different LED types. Most are one of these two, but yours may be different.
- WS281x covers most RGB pixels
- SK6812 covers most RGBW pixels
Color Order
You will most likely need to adjust the color order. If you're telling the LEDs to be blue, but they are turning green, then you need to swap those colors. For RGBW pixels you might also need to swap the white with a different color.
Length
Adjust this as needed. A lot of 12v strips will have pixels controlled in groups of 3. If that's the case, then take your total number of pixels and divide it by three. For example, if you have a 5m strip with 150 pixels, you will need to set the length to 50.
GPIO
Keep these the same (32 & 33) or nothing will work.
