Need a simple PIC code urgently... please help
PostPosted: Wed May 09, 2007 7:17 am     Reply with quote
hi all...

I need a code to generate a pwm output from my PIC micro controller, the one m using is PIC16F877A,The PWM duty cycle should keep varying based on few conditions. the conditions i'll put on my own, just if I can get a code outline....


Also i need an interfacing program . I need to interface 2 things, one is a RPM sensor, which gives continuous pulses as output. These pulses need to be counted.


Another sensor which just gives an output voltage in the range of 4 volts has to be read into any port pin... basically port A...

Please help me out wid de codes... need it urgently.. Sad

This one doesn't count pulses. It uses CCP to count time between pulses
and converts that to a frequency.
