Hi, I am using the olimexino-328 and the ecg shield from olimex. I am using the demo code and elecguru40.
In the demo code I would like to know which variable saves the read signal, I would like to make a condition in order to obtain an acoustic feedback when the signal reaches a certain level of activation, therefore I need the aforementioned variable.
The demo script is sending the ecg values over the serial port to your computer. You need to receive them there. (values between 0 and 1023)
