stm32f767zi max interrupt speed

I would have a question I am using stm32f767zi and trying to capture 2mhz signals with interrrupt

600 700 khz is not much trouble, but 1mhzlerde starts to catch the deviation. Captures the rising and descending edge

I wonder how another method can be applied for this or how this can be accelerated interrrupt

Hello,

I would suggest you to capture your input signal using timer in input capture or input PWM mode.
