I have completed a Total Control Lighting C library for embedded linux single-board computers, such as the BeagleBone, BeagleBoard-xM, and the Raspberry Pi, which support Serial Peripheral Interface (SPI) bus. The library is available to download from bitbucket.org. There are a few sample programs and some documentation included with the download. Total Control Lighting LED strands are fully controllable 3-color LEDs available in strands of 25 or 50 from coolneon.com. You can do some pretty amazing things with Total Control Lighting as in the videos below.
