Hi Cooking Hacks team,
yesterday I successfully wrote my first heartbeat with my eHealth module on a raspberry pi 3:
I followed your instructions to start, but I am now having a simple question:
The input value is a 12 bit unsigned integer (values 0-4095).
In your example you map this value down to a float on a range from 1.0 to 5.0 and you tell us it resembles Volts.
In my knowledge an EKG signal is usually measured in mV (milli Volts), see Wikipedia:
ECG voltages measured across the body are on the order of hundreds of microvolts up to 1 millivolt (the small square on a standard ECG is 100 microvolts).
