Calculating Time Between two rising edge

[makram]

Hi Everyone,
Can anyone please suggest me an effective way to calculate time between two rising edges.
and i'm reading this rising edge on our GPIO pins

You'll need to supply a bit more information for us to offer a meaningful reply. What is the minimum time interval you expect to measure and what accuracy are you hoping for? As a very general point, if you're talking sub millisecond accuracy ESP32 is not very good at this kind of thing, at least until RMT input is supported.
