If you mean from trailing edge of pulse Number 1 to leading edge of pulse Number 2 then, Yes. The pulses are the same time apart. If you mean leading edge of pulse Number 1 to leading edge of pulse Number 2 then they are not always the same time apart. The width of the pulse controls servo position. for example maybe 1mS.....1.5mS......2mS is Left..Neutral..Right. > I am >trying to time the signals but only have 2 timer pins on the micro >controller that i have (motorola hc08) one of them is being used for a >tachometer counter and the other was going to be used for the duration >of a servo output. So i'm left with one other servo signal in that i >need to distinguish the time of the pulse for an on/off function for the >circuit. Any suggestions are welcome. > Just for interest, what are you building? Regards, John Crighton Hornsby Heights.
