    Handling partial data transfer on PC side. AN75779

    btaylor_2212921

      I'm wondering the best way to handle a partial data transfer on the PC side?  On the FX3, my DMA callback gets executed during a partial buffer like it should and performs the proper steps however, on the PC side I don't know the proper way to handle data xfer.  I always get out of sync.  I don't know what the size of the data xfer is and what to put in "bytes" length to xferdata function on the PC side.  Is there away to stuff the buffer on the FX3 side so the buffer is always the same size?  What is the best way to handle this situation?

         

      Thanks a ton for the help!
