the FPGA code was fairly simple actually. It just checks the 4-bit preamble sequence to make sure it's a valid, and then works as a modified shift register for the 32x2 bits. I think the coolest part is that we managed to encode the instructions for the light sequence within the actual audiostream outside of the range of human hearing.
Especially cool considering that it isn't running any software other than the compiled FPGA code.
