Hi 

 

I am currently working on STM32F3 discovery board. I want to calculate the number of rising edges that can occur in certain time period. Currently I am doing this by setting up an external interrupt pin and a timer.

 

At a frequency of about 750khz I am loosing the pulses. 

 

I want to know what is the maximum frequency of the signal that can be given as an input?

 

Thank You
