Dear all,
Now I want to use two gpios(as clock and data) to transfer a Bit-Stream.
I tested the gpio clock frequency is 1.7MHz with using write register mode to config it. But when I transfer the data using the clock, the gpio frequency will be reduced to 1.1MHz.
It is too slow for me. I need the gpio frequency as high as possible.
Does anyone have a good idea?
Thanks
chad

Hello,
For your project, the SPI is a available or not?
The SPI allows a faster CLK signal than 1.7MHz however it depends of your design.
Could you give us more details about yours requirements and limits?
yours,

Dear Rob1,
My SPI has been used for a spi flash, and my FPGA need to work at slave serial mode. So we want to use GPIO to connect with FPGA.
When we transfer a bit-stream to the FPGA, we find the speed is too slow.
Best Regards,
chad
