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!!
