I’;ve been using FastLED for a little while and built a few projects using WS2811 pixels.

I’ve acquired some WS2801 based pixels and cannot get them to work. (I have two different types from two sources and neither work)

I’ve tried using default CLOCK 13 / DATA 11 and instantiating FastLED.addLeds<WS2801, RGB>(leds, NUM_LEDS); and also defining the two defines and using FastLED.addLeds<WS2801, DATA_PIN, CLOCK_PIN, RGB>(leds, NUM_LEDS);

Just to test the pixels, I’m using the FirstLight example (so nothing complex)

Any ideas?

Forgot to add, I’m using a Arduino UNO, and have external 5v bench PSU, and the same program works with the 2811 pixels I have.

Please ignore. The gods were conspiring against me, and I had two dead pixels at the start of the chain. A few literal binary chops (and resoldering) resolved this.

Great Library, I’ll post some piccies of the projects I used them in.

Hi Francis- glad you’ve outwitted the gods … this time! Looking forward to seeing what you create!

@Francis_Reader I run into the same problem with my bench power supply. It seems that my bench power supply isn’t very nice to electronics when I power it on - sometimes pushing 30+ volts for a brief instant. So now I use dedicated 5v and 12v power supplies to test LEDs.
