I’m still having problems with my FW1906 strips.
The color order will be randomly picked by a manufacturer to get best strip layout for the copper lines.
So we should be able to easily set the colors after the below mentioned test to find the correct order.
From the Neopixel form:
A quick way to test color order is to do something like this…
Use this definition NeoPixelBus<NeoRgbFeature, NeoWs2812xMethod>
Then use this sample to set the colors…
strip.SetPixelColor(0, RgbColor(255,0,0));
strip.SetPixelColor(1, RgbColor(0,0,0));
strip.SetPixelColor(2, RgbColor(0,255,0));
strip.SetPixelColor(3, RgbColor(0,0,0));
strip.SetPixelColor(4, RgbColor(0,0,255));
strip.SetPixelColor(5, RgbColor(0,0,0));
strip.SetPixelColor(6, RgbColor(0,0,0));
strip.SetPixelColor(7, RgbColor(255,0,0));
strip.SetPixelColor(8, RgbColor(0,0,0));
strip.SetPixelColor(9, RgbColor(0,255,0));
strip.SetPixelColor(10, RgbColor(0,0,0));
strip.SetPixelColor(11, RgbColor(0,0,255));
strip.Show();
Then note the pixels that are lit and the colors in order.
Attention: My strip has a different order of the used colors as you can see in the photo.
