Hi guys,

I want to make an application with Arduino and these chips  but I can not find information =( =( =( =( =( =(

does anyone know where I can find this information :) :) :) :) :)

Many thanks for help ;) ;) ;) ;)

You should use this library. 

Note that the pins used on an UNO are 11 and 13.  You cannot change these pins with this library.

i have two rgb strip with lpd 6803 but one is rgb and one is changed colors bgr... is it possible to make a converter that converts rgb to bgr ..?

Check out the fastspi library - http://fastspi.googlecode.com (with a preview of the 2nd generation of that library documented at http://waitingforbigo.com) - it supports all of those chipsets, and FastSPI_LED2 allows you to use any set of pins that you want (it will flip from hardware SPI that realistically maxes out at 6.6Mbps to software SPI that maxes out at somewhere closer to 2.7Mbps if you use other pins)

@mortenx - one thing I'm going to be adding to FastSPI_LED2 (hopefully in the next couple of weeks - life and work are eating up a bunch of my time these days!) is the ability to specify the rgb ordering for any particular set of outputs - so that you can handle the rgb/bgr/gbr/grb juggling that some of the strip mfgrs seem to do.

(other things coming - faster hardware SPI on the teensy 3, DMA support on the teensy 3, a couple more chipsets, the above mentioned rgb ordering juggling, etc...)
