    Is there an event "USB-transfer completed"?

      Hi,

         

      in my FX3-firmware I set up the DMA-channels at USB-side to use external DMA-buffers. This works fine so far!

         

      Now I'm looking for a possibility to get signaled new USB-transfers arriving in FX3 while my firmware is handling the data of one received DMA-buffer. The dma-callback doesn't help here since it's only possible to let it raise in case of the event CY_U3P_DMA_CB_RECV_CPLT which occurres only if a DMA-buffer is received by firmware calling CyU3PDmaChannelWaitForRecvBuffer().

         

      Has anybody an idea how can I catch completed USB-transfers in the FX3-firmware?

         

       

         

      Best regards,

         

      Robert
