The aim of this project was to transport both digital audio and power to a speaker using a single Ethernet cable. Transmitter/Receiver PCBs were designed and software written for the L1 64 pin device.
A lightweight software stack transmits audio from S/PDIF over Ethernet, recovers a clock at the receiver and outputs/amplifies the audio using a digital input Class D amplifier.
This project was submitted as a final year project on the MEng Computer Science & Electronics course at the University of Bristol.
