StageConnect: Arduino Library for A²B Audio Bus Implementation Using Analog Devices AD242x ICs
By

A weekday bagel. Dependable, satisfying, no fuss.
Summary
StageConnect is an Arduino library that enables creation of devices using Analog Devices AD242x ICs (like AD2428) to implement the A²B automotive audio bus technology. It's designed to connect audio equipment like Behringer WING to Midas DP48, transmitting 32 channels of uncompressed 48kHz 32-bit audio through simple XLR connectors. The system uses virtual I2C connections routed through the A2B link for communication between main and subordinate devices.
