Heart-Beat Counter Using MSP430

Introduction: Heart-Beat Counter Using MSP430

hi friends, here is my project on counting the heart beats using an MSP430G2553, and a dual op amp ic, LM358, i think any other dual op amp can work in its place [to be sure, just check the pinouts before replacement]... :)
it displays the heart beat on the LCD screen, i found this project on internet, but it was done with 3 seven segments and with PIC micro controller, so i thought to build a very compact circuit with MSP, i have given the c code, for which you will need the code composer studio, with the launchpad kit...

i hope you enjoy building this project, i have uploaded its video in the files, with the eagle's schematic files, thank you :)

    Hi, please let me know why you set the value of CCR0 is 50000 and i is i<350, if I want to set the Timer run in 20s, how can I do that?

    Can I ask you a question? How many voltage drop on IR LED and PHOTODIODE when the circuit is running?

    i dont know actually, and neither do i have circuit with me now, i think it will be approximately 2 volts...
