[Help!] Demo of EKG recording

[bonbonking]

Hi Everybody, I'm a computer science student who is currently working on a EKG authentication project. Now i'm using TWR-MCF51MM-KIT (which is a medical-oriented development tool for the MCF51MM256 microcontroller ) (http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=MCF51MM) and a Medical EKG board ( http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=MED-EKG&fsrch=1&sr=13 ) as my device to collect EKG from different people. I've just got started and I've succeed in running a EKG Lab on CodeWarrior v6.3 with a MED-EKG GUI. But my main challenge is to collect these EKG data from the device. I have several rough ideas, like I should use USB PHDC to retrieve data and then process them. But I'm really lost right now. Can anyone give me some ideas about where to start and how? Many thanks in advance!!

Hey, I'm in your same situation, although I think I'm a step behind,

I've programmed the kit to run LAB1, and whether I use the on-board electrodes or an external electrode, I get a signal that's only fluctuating between -16000 and -13000, 

Sometimes it fluctuates also between that range and 0

You can see the pictures

"Previous sections have mentioned that the GUI communicates with the microco ntroller via USB port, using the Freescale USB stack, which performs an algorithm that creates a virtual serial port to send and receive data"
I've noticed this from a tutorial...don't know if this bring some information......
