I bought 50 x WS2801 LEDs to test with my ambi-tv. I used gfix fork of ambi-tv (where he added WS2801 support) but my LEDs only show RED (and only the first LED shows white). I am using the mood-light to test (as this doesn't require and video input).
I have connnected the DI to the correct pin, and the LEDs are powered from a seperate power supply to the Raspberry Pi. LED ground is connected to it's own LED power supply. Raspberry pi is powered by a seperate normal mini USB -> 5V power supply adapter.
Any ideas? Do I need to connect the Pi and the LEDs to the same power supply so the grounds are connected to the same place?
Hi guys please help me!! I am driving myself crazy.
I went and bought 2 more WS2801 strips (50pcs) and tried those and they also don't work, but more LEDs light up on these 2 pairs than the last one. I can make a YouTube video showing you what the problem is but basically when testing with gfix ws2801.conf and the included sample.conf it it doesn't work. Colours are flickering (and don't seem the right colour), and some LEDs don't even turn on..
I have wired the Raspberry Pi and the WS2801 strip to the same power supply (so same ground, V+ etc.).
I have also tried PixelPi (just to try and turn the LEDs on and off, but this doesn't work properly either. only some LEDs turn on and off, and when trying the fade/chase etc these do not work).
Please help Thanks
