McBSP SPI Example

Hello all,

I am using McBSP0 on the C6713 to control a DAC and ADC at the same time. The DAC (TI's DAC7611) is working fine. However, I can't get the ADC (TI's ADS8320) to work!!!

Any ideas on how the receive part of the McBSP should be configured for this purpose??

This is my current configuration:

MCBSP_Config DAC_Control = {
