From the project
A digital modular audio system
An class D amplifier module that can select other digital sources (I2S, S/PDIF).
Select sources Receive input fron the volume control and adjust the volume over the DSP. Receive input from the button banks. These are used to interact with the display. Interface with an (Airlift) Wifi board over an extended SPI interface. This is used to download station lists and also to control the internet radio module.
