Hi there,
I want to change the speed of GPIO for STM32f4 discovery board. The maximun speed I can get on specified pin is 6 MHz and I want to get 20 Mhz. we know that the discovery board has external clock circuit to operate at high speed. I do not know what to do to get higher speed. By the way I am using Keil (uvision) software.
Thanks for any help
