Software and firmware for the AD8232 heart rate monitor.
Web page for this project:

I originally wrote this back in 2014 and decided to move the files to github. Basically this project is 2 parts: 1) Firmware for an MSP430G2553 chip that communicates with an AD8232 heart rate monitor board made by SparkFun and 2) Some Objective-C / SDL software to run on a PC that gets fed data from the MSP430G2553 displaying the data like an EKG monitor.
There is a video on the web page.
