Storing Data from DMA to SD Card



Hi All,

I've been working with the CSL and managed to make a project that saves ASCII characters to the SD Card through the CSL & BIOS. I have also worked on another project (which is basically a cut down version of the Audio Filter demo) to retrieve data from the Codec using DMA. I wish to combine these two projects, so that i may save this data to the SD card continuously. However whenever I try to bring the attached code into a project with BIOS/CSL it no longer works. Could someone please point me in the right direction of adapting the code to work with CSL & BIOS, ultimately I'm basically trying to sample from the Codec using I2S/DMA and save the data to the SD Card.

Attached is the project for the I2S/DMA project.7418.DMAPingPOng.zip

Kind Regards

James
