Hello all, Can the TI '5509A DMA be used to take 16-bit data from a MCBSP port (from a audio ADC, using I2S framing) and dump this into RAM buffer like this: 0x0000 left[n] 0x0000 right[n] 0x0000 left[n+1] 0x0000 right[n+1] etc where left[n] is the nth 16-bit (left) sample from the McBSP. I think I can do it using the "single index" mode with an appropriate index programmed into the index register (since the source will be set to "no increment", I think I can run the '5509A's DMA in the "Compatibility" mode, where the src and dest indexes are common). Am I right in thinking this will work? Many thanks, Ian
