iv got a square wave pulse from a anomemeter that i want to display on a lcd, it pulses 6 times to one rotation of the anomemter.
i believe that the maximum frequancy i need to measure is about 150hz
what is the best way to count this with a micro pic, trying to use a 18f with mlab c18 compiler.
i was thinking of setting up a tmr0 timer and count the pulses till it overflows and then see how many pulse there are in that set time, does this sound right or should i do it another way.
with no rotation of the anomemter the output sits high (5v) and pulses down to 0v when rotated
thanks for any help
