Hello, I use DSK6711 and I would like to program EDMA data transfers from/to the on board AD535 audio codec. I would be very grateful if someone could send me some C code example to do so. I am aware CSS contains some of this examples, but I dont want to use CSS. Many Thanks Eduard. |

Dear All, I came across this build which is meant to use AD535 audio codec with EDMA data transfers. Unfortunately, it doesn't seem to be working for me... If anyone there was able to spot what is wrong, I would really appreciate you could drop me a line.

If you are interested in using the on-board audio codec AD535 with EDMA
data transfers outside CCS, you can use the software I attached to my previous email: http://groups.yahoo.com/group/c6x/message/1561 The reason why it didn't work is because these two lines were missing from the target initialisation code: #define IER_NMIE 0x00000002 #define CSR_GIE 0x00000001 /* Enable global interrupts now. */ IER |= 0x00000001 | IER_NMIE; CSR |= CSR_GIE; Regards, Eduard E Oliver <> wrote: Dear All, I came across this build which is meant to use AD535 audio codec with EDMA data transfers.
