Is there a way to count number of pulses using a timer? Preferably using a strobe. I want to count number of pulses over a period of time, and get an interrupt at the end.
Is there an API for that?
Configure TIMER to count pulses.

I do not know of any API which will allow you to do this. If I needed this functionality I'd think about either using two interrupts (one for the timer and one for the signal) and do all of the work in software or use an external counter and a timer and read the value from that when the timer triggers.

How fast do the pulses come? If they're more than a couple Hertz, a more reliable idea might be to use a 555 timer set up as monostable in conjunction with a low-pass filter and then read the result using an analog input.
