Description of item(s)/value to others: This example shows how setup the DSP peripherals for a simple audio application with the "standard" Chip Support Library
(CSL) instead of the C5402 DSK Board Library. The DSK Board Library is not supported at the same level of CSL and sometimes doesn't give to the user the complete control of the DSP.
This lab project is derived from the TI Reference Framework #1, leaving only a very simple framework that should be easy to understand for a first time user. The original Reference Framework can be downloaded from http://www.dspvillage.com.
