Im sending serial data from a PIC18 microcontroller to the PC com port. Im using a USB cable to do this by using a virtual port that emulates a COM port. I am expecting to graph the data since it is a patience's heart signal. My question is will I be able to calculate the heart rate in labVIEW. will I be able to display a warning when the signal goes below a threshold value? If so, are there any examples related to this ..
