Example

% This code reads an incoming int32 from MATLAB

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

ArCOM serialPort; // Create serial port object

long myInt = 0; // Create an int32

void setup() {

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

}

void loop() {

myInt = serialPort.readInt32(); // Read an incoming int32
