Catmacey has been working on a digital guitar effects processor based on a PIC32MX, the ChipStomp:
Here’s another “Guitar stomp box” project…
This one combines a Chipkit DP32 (PIC32MX) with an Open music labs Stomp Shield to sample audio, mess with it and squirt it back out at 44Khz.It uses the built-in 10bit ADC for input and two 8bit PWM DACs to provide a 16bit output. It’s a clever solution to use two “small” high speed PWMs mixed like that, thank you Open Music Labs.
