Hi Vern H,

Are you referring to this code? If so, that is written to use the Pulse Sensor with an Arduino and the Arduino IDE, not Eclipse so you most likely need to modify it to work with Eclipse's C/C++ IDE. I am afraid SparkFun Tech Support cannot assist with custom code. You may want to look at the Eclipse forums or their Help Documentation to adapt that code for use with Eclipse.
