WebJul 30, 2012 · 1. You set the GPIOs' speed to 100 MHz; this is the speed limit the hardware can support. But the final data exchange speed may also be limited by how fast your code can run, because the data clock, etc. is driven by your code now. In my opinion, not all STM32 family members support the 100 MHz GPIO speed, and some family's MCU … WebAXI GPIO maximum toggle speed. Hello! I am working with zedboard. I am trying to extract data from a host computer to zedboard via ethernet. The data is then converted into serial form and wrote into GPIO output pin.
