16-bit I2S on an iCE40

I2S DAC

An I2S 16-bit audio codec I made to do audio DSP for my open-source iCE40 FPGA. I had to get digital protocols working between the ADC and a DAC.

Simple passthrough

A simple audio passthrough through my FPGA. So much work into a sine wave...

Encoder knob

To control the parameters of the digital effects I added rotary encoder functionality in hardware.
