Communication between FPGA and CYUSB3014
Now, I have transfer the video data from FPGA to CYUSB3014, and AMCAP could display the video.
However, my video format is flexible, not fixed; how can I send the video format information in a register in FPGA to CYUSB3014 and receive the required video format information, which should be useful in FPGA video processing, from CYUSB3014. Is there any feasible communication method/protocol? Could any interface embedded in CYUSB3014 be used? If any, which is best, UART, SPI or I2C? Or using GPIO is enough?
