Audio Development Platform

The Audio Development Platform (ADP) serves as a development platform, a demonstration vehicle, and as a basis of a reference design. The DAE-6D, HD-79 and ADC-6 modules all plug into the system.

The ADP's motherboard provides a complete set of analog and digital audio connectors and a connection point for a power supply. It also also provides, volume controls on the analog inputs and outputs, bypass relays to connect the analog inputs to the primary analog outputs, and mute relays on primary and secondary analog outputs.

The front panel board, which includes a character based display, allows prototyping user interfaces.

Internal expansion connectors allow access to the I2S audio and I2C control busses inside of the system, allowing users to combine this with their own prototype hardware to create a software development platform.

Two Philips LPC2148 (ARM) based processors are in the ADP. One, in the motherboard, controls all of the modules and provides serial port and USB control. The other is located on the front panel board and abstracts the user interface from the main control functions.

The ADP is provided with source code and schematics to the board to reduce the effort needed to design an AV Receiver around the DAE-6D.
