PIC to TSL230R interface: Heart Rate Detection! Plase Help!

[eppemon]

Am using PIC16F877A to detect heart rate. The IC TSL230R (Light to frequency converter) will give the output as frequency variations. The light passing through the finger will reach the light sensing part of the IC and it will give the output as frequency variations. But I don't know how to calculate the heart rate from this.

Please see the attachments I used for study.

That looks like fun I need one of them My self doc thinks I smoke but I haven't

I'll put one of them together I have a bunch of TSL230R See if we can see the beat.

This could work I hooked up some hardware to my scope nows time to get the code to read the heart rate
video not the best but you can see how it changes when you put the monitor on .

I have some usable data working on some usable math. I'm getting about 76 beats a minute

I started back on this and I have it working! My heart is beating 67 beats a minute and I'm reading 67 beats with a logic tool

So i now no I have the hardware working and some math to plugin back to coding a pic to count them

Hello
After Thanksgiving Thread
Is it possible to get PIC code of necessity
Thanks

I have not worked on this in a long time and the code I had I lost thanks to a computer crash.
