Overview

The Walcott visualization integrates a set of rewired christmas lights into the Bemix system. A custom XMMS plugin running on Cocoa Table calculates five 0-255 values based on Fourier transform of the music playing in the lounge. These numbers are wrapped into a 4E Network packet and sent to the serial port to a PIC microcontroller. The PIC parses the packet using BemixOS technology and sets the brightness of each color of light using PWM.

Hardware

The visualization uses a PIC to decode a 4E Network packet containing six 0-255 values. The packet should look something like:

(channel 1)
(channel 2)

(channel 4)
(channel 5)
(channel 6)
\
E

These values become the duty cycles of six software PWMs running in the main loop of the firmware.
