FPGA and PC problem
I am now using USB3.0 to transfer data. The FPGA control squences is that at first 500us FPGA do nothing to USB FX3 , and then transfer 128KBytes continuous data to PC, and then it follow the cycles.
But I found that the 500us void time pend my transfer. If I set the void time to 10us or less. The PC will get data without any problem. So why this problem happened.
I increase the value of the waitforxfer() parameter. But the problem is still there. thank you.
