USB Audio hardware platforms

This section describes the hardware development platforms supported by the XMOS USB Audio reference design software.

Board	xcore device	Analog channels	Digital Rx/Tx & MIDI
XK_EVK_XU316	xcore.ai	2 in + 2 out	N/A
XK_AUDIO_316_MC_AB	xcore.ai	8 in + 8 out	Supported
XK_AUDIO_216_MC_AB	xcore-200	8 in + 8 out	Supported

Each of the platforms supported has a Board Support Package (BSP), the code for which can be be found in lib_board_support. The code in lib_board_support abstracts away all of the hardware setup including enabling external hardware blocks and DAC and ADC configuration and provides a translation layer from the common API supported by lib_xua for initialising and configuring hardware on a sample rate or stream format change.

Detailed feature sets for the each of the supported boards can be found in the documentation for lib_board_support.
