if this is a debian / raspberian library deb package then of course yes it does !

nice ill play with this when i grab a second Pi and see how feasible using JUST the pi for this setup would be

as promised guys

PPS
"in theory"

this mod would work using the on board SPI interface (GPIO pins on pi) using the SPI lib broadcom provides wich can be installed as so:

wget http://67.192.60.197/mikem/bcm2835/bcm2835-1.5.tar.gz
tar xvfz bcm2835-1.5.tar.gz;
cd bcm2835-1.5;
./configure;
make;
sudo make install

then wire the LPD8806 Chain to the Pi as we find here:


make sure you only power your pi using the 5v pin on GPIO not 5v + micro USB

quick way to fry it

i personally dont like using that 5v pin when i tried that setup on a different distro i left the 5v pin unattached and just left it running from power->leds and not to pi

change boblight.conf to the one found here
https://code.google.com/p/boblight/source/browse/trunk/conf/LPD8806.conf

( you can replace the LED part starting at the first LED#1 entry with your old conf so you know its layed out for 50 leds the way you've mounted them according to the guide)
