Parallel communication with Basys 3

Question

I have connected an ov 7670 camera to my Basys 3 board and want to transmit the frame to a PC via the micro-usb port. I have tried UART serial communication, but the bit per second rate is simply not high enough to transmit a full 640 * 480 frame 15/30 times a second. I had the idea of implementing some sort of parallel communication, however I could not find any information or guides. I was wondering if anyone could help me out either with parallel communication, or suggesting a different method of transmitting frames to a PC.

 

Thanks in advance.

Hi,

UART doesn't even get close.

Using an external FTDI minimodule might work (e.g. single-channel synchronous FIFO mode up to 40 MBytes/sec).

Here is one board that shows how to connect it for FIFO mode (page 2). Note, it uses the 2nd ("B") port, the "A" port is serial JTAG.
