Everything is working except the fact that the green and blue color are inverted. When I display a blue image the LED turn green and when I display a green image the LED turn blue. Please help.
It seems like we have the same led strips. You need to modify the lpd8806 sink c-file, to change the order of the green and blue output and recompile. If you don't know how to do that, I can always give you my binary file.

Thank you for your help. I will appreciate if you can share your binary file with me as I don't know how to modify and recompile the lpd8806 sink c-file.
Thank you,
@andyclarke yes, I will add this as an option soon – apparently, there are lots of different strips out there with the LPD8806 chipset, but they seem to have the LEDs connected to different driver pins at random...
I had this problem and changed the "b" and "g" around on lines 217 and 219 in src/components/lpd8806-spidev-sink.c
Recompile (make) and it seemed to do the trick.

I figured it out. Thanks.

These are also swapped on my LED strip. Perhaps this should be added as an option in the config file.

Hey everyone. I need help with how to reverse the green and blue sync.

I now just need to sort out my gamma levels...
duenorh commentedon Sep 9, 2013
Thank you. That worked like a charm.
I've got bigger problems then gamma levels. Seems like my soldering needs to be redone.
