hi

can anyone please help me, i'am making a speedometer for my electric bycycle, and need to messure pulses between 0-70hz and do some math to get the Km/h

i,am using pic16f877 with 16Mhz and pic basic pro.

maybe with interrupt, because i have to messure amps and volts at the same time, and at a low freq, the loop will take to long.


sorry for my bad english :-)
