Part Number: TMS320F28335

Hi all:

U16 SendBuf[256*4]; // defined in XINTF ZONE 0 (extern memory xintf)

U16 RecvBuf[256*4]; // defined in XINTF ZONE 7 (extern memory xintf)

I want to move SendBuf to Recvbuf through DMA channel 2.

How could I configure the dma especially the register "DmaRegs.CH2.MODE.bit.PERINTSEL"? I wonder which event or interrupt could trigger the DMA transation.

Hi Li,

Apologies for the delayed response. You can configure the Trigger as 0 which means the channel is triggered immediately after the RUN bit is set
