    How to achieve the more throughput from Full speed USB

    yv.subbarao

      Hi,

         

      I am writing program on psoc3 microcontroller for USB communication. In this application i want to send maximum data from microcontroller to PC(VC++ program).  I wrote program using one Bulk In endpoint  and achieved speed of 0.25Mbps. I understand about usb that it sends 1 frame/msec. Each frame having 14-19 transactions(or packets). But one bulk in endpoint sends 64 bytes each time. I don't know how to increase no. of transactions per frame using bulk in endpoint and at the same time how to get entire frame with XferData using from CyUSBAPI  in VC++. Can you help how to improve my throughput in full speed usb microcontroller with bulk inendpoints.

         

      with regards,
