    FX3 DMA transfer from RAM

    kennedy_2701666

      Is there a way to set up a DMA transaction from an arbitrary RAM address using the FX3?  In all of the example code I have seen, a buffer is first retrieved via CyU3PDmaChannelGetBuffer, the data is copied into the returned buffer, and then the data is committed via CyU3PDmaChannelCommitBuffer.  I have a couple of large static buffers that I'd like to switch between periodically and am hoping to eliminate the copy operation.

       

      Thanks.
