EKG-EMG Shield Firmware Program Flow

[gianinna]

Hi,

I recently bought the EKG-EMG Shield for Arduino for my undergraduate project. I'm trying to develop an ECG / Heart Rate monitor for use during exercise.

I've tried studying the demo code ShieldEkgEmgDemo.ino for it, but I'm having a bit of a hard time putting it all together.

I was just wondering if anyone here knows where I can find a better documentation of the demo code? Or a documentation / explanation of how the EKG-EMG Shield works and transmits data to the PC?

I want to understand how the raw transmission of data works, because I'm going to develop a program that will save the actual ECG Signal values to a .csv file. I will be using Arduino + Python.

Can anyone please explain to me how the ShieldEkgEmgDemo code works, like the actual program flow for it? I've been searching the internet but haven't found any.

I would really appreciate any kind of help. Thank you very much!!

P.S. By the way, I will only be using it for 3-lead ECG, so I assume that means 1 channel only?
