I have been using PIC18 micro-controller for generating reference signal and a charging signal at 100 Hz rate max. Now I have to generate this charging signal on sensing an external trigger pulse of width 15us with frequency in between 1 to 100 Hz. I am already using all the 5 timers of PIC18 for different purposes.
I am thinking of using external interrupt on rising edge but how to check 15uS pulse width. I mean what if the external pulse only rises to logic high and doesn't go to logic...
