DMA with auto initialization - eli_zarka - May 29 8:31:00 2003

Hi all, I am using a DMA channel with autoinitialization. I have a frame of 4 16-bit words. My question is how I have to configure the DMA and the McBSP in order to synchronize the DMA to the frame sync signal. The problem is that the McBSP gives an event every 16-bit word and this is not good because I have to start the DMA transaction at frame sync (Every 4 16-bit words). Thanks, Eli. |
