The goal of this project is to perform real-time digitization of an analog audio waveform, and then to make the digital data-stream available for manipulation within the Linux user-space via the “Advanced Linux Sound Architecture”. The Analog-to-Digital Converter (ADC) is a type MCP3008 and is connected via SPI bus to one of the two “Programmable Real-Time Units” included with the Beaglebone system.

Detailed documentation is in the file PRUADC1.pdf
