hi,
i am using a pic16f877a on hi-tech using mp-lab. i basically have a circuit which finds out the pulse rate of a person. when a person heart beat the circuit output move from 0v to 3.7v. i need a software to count every time the output peaks at 3.7V over a set amount of time. so i can calculated the projected heart rate of the user and also i have connected an LED to another port to blink whenever the micro controller counts a pulse
Please help me i am really confused on how to program this. i have connected the output of the circuit to
RA4/T0CKI/C1OUT of the micro controller and the LED to RB2 .
Any help will be much appreciated.
