please help me out with a programme for measuring frequency from 1k to 1.5k
The most efficient code is quite often _not_ code, but actual hardware.
Have you looked into the possibilities of your timers and/or pwm functions of the chip? Can you start/stop a timer from the outside, with the state change of an input pin?
well.i ve to measure ontime only....i'm feeding my uc from signal generator for testing purpose but my code is n't working ...can u plz help me out with some efficent code
Exactly what help do you need?
How far have you already got?
Where are you stuck?
Hint: remember that frequency is the reciprocal of time - so you might want to measure an appropriate time interval, and work-out frequency from that...
