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?
Usually in our example projects, we use the I2C interface between FX3 and Camera (or FPGA) to send / receive video control and other info related data.
You can also use I2C in your applications.
