Configure DMA for DAC with Processor Expert
Description:I have tried to configure CW10.1 using processor expert to transfer by DMA to the DAC.....

I have two data buffers, one is being DMA'd out to the DAC at a specified rate, while the other is being filled, once the buffer being transferred is done, it switches to the other one.

Its an audio application I am sending data to DAC at 32Khz..... So I would think I could use PIT or similar to trigger the DMA transfers.....

Can you walk me through the setup?

Send me demo code already doing this?

I have K60 Tower kit and CW10.1 fully updated.
