Sloth (a collection of bears)
WS2801 (aka 'Dream Colour') LED light strip control from the RaspberryPi. Relies on the AdaFruit Occidentalis Raspian image. The main purpose of this setup is to display build information from our Jenkins server, but it is intended that other displays can be easily added.
Development light-show visualization:
The sloth script accepts one parameter which is the driver used to display the lights. Supported drivers are:
- WS2801: draw led data to a SPI led strip
- Visualizer: pops up a raster window representing the led strip
By default sloth will load the WS2801 driver unless other driver is specified. Use the following command in development mode:
sloth Visualizer
Note that DriverVisualizer requires ActiveTcl on OS X and TkInter on Linux.
