Sarath,

I'm moving this to the Medical Forum. It has a better chance for an answer here.

Hi,

thanks for the reply , but i guess the folder contains the source code for SPO2 appilcation only.

whereas i am looking for heart rate monitoring application.

Isn`t there any difference between the two?.

Sarath,

This is the source code for our AFE4403EVM. This EVM does heart rate. You downloaded what is highlighted in red below right?

Sarath,

Saturation will be at 1.2V. Do you mean other techniques to calculate HR?

Sarath,

You can read about many other techniques from academic papers. Here is one from a quick google search.

Thanks alot. that was very helpful,

While trying to use the AFE4403EVM GUI the board is not getting detected. The USB driver is not installed properly, I tried installing it as mentioned in the reference manual and still it didnt work out. My OS is Windows 8 64bit and am attaching a Snapshot of the error.

Thanks in advance.
