Example

% This code reads an incoming int16 from MATLAB

#include "ArCOM.h" // Include ArCOM library

ArCOM serialPort; // Create serial port object

short myInt = 0; // Create an int16

void setup() {

SerialUSB.begin(115200); // Initialize USB serial port

}

void loop() {

myInt = serialPort.readInt16(); // Read an incoming int16

}
