Application provides unprecedented access to the A²B system. By attaching the A²B Adapter Board in-line between A²B nodes, the A²B monitor can non-intrusively sniff A²B data on the line, giving users a real-time view into A²B traffic on the bus. A²B superframes are decoded and disassembled into I2S/TDM audio data and I2C control data for easy debugging. Additionally, full reporting on Interrupts and GPIO handshakes are correlated into the data capture.
