I want to generate 16 MHZ clock signal from Nucleo-F746ZG development board. I have used FastPWM library to generate 16 MHZ clock on PA_8 pin. But not able to see square wave on CRO. Can someone please help

#include "mbed.h" #include "FastPWM.h" FastPWM fastpwm(PA_8,1); int main() { fastpwm.period(5.25e-8 ); fastpwm.write(0.5); }This is my simple code to generate PWM in MHZ using FastPWM. When i check on CRO its showing frequency about 16 to 19 MHZ b...
