Hi,

I am sorry I an not clear about your question.

You have a c# or c++ windows program that must speak with an Arduino program using usb?

or

You have an arduino .cpp file in an Arduino project. The .cpp needs to have access to Serial?

Thank You for your reply. I have a c++ file, and i want to communicate with my stepper motor using arduino through serial communication(USB port)

Okay this forum is reallu just to help people get the ide running. The best place for answers is http://www.stackoverflow.com

I can give this info but it might not help you ...

Does your C++ have access to windows .net objects such as System.IO? If yes then you can use the SerialPort object, is No then you need to search google for C++ Serial Port code for windows.

On the Arduino you do something like this:-
Code
Select All
void setup()
{
  Serial.begin(115200);
}

void loop()
{
 if (Serial.available()>0)
{
  char cmd = Serial.read();
 
     switch (cmd)
    {
        //command = motor
        case 'm':
        {
        //stepper angle
        char angle = Serial.read();
        //
        break;
       }
    }
}

Thank You. Let me show you my code. I am using a variable 'incomingbyte', and i want to control it with my c++ code. Any Help will be really appreciated. 
Code:
#include <Stepper.h>
const int stepsPerRevolution = 200;  // change this to fit the number of steps per revolution
// for your motor
int incomingByte=0;
// initialize the stepper library on pins 9 through 12:
Stepper myStepper(stepsPerRevolution, 9, 10, 11,12);
void setup() {
  // put your setup code here, to run once:
  // set the speed at 60 rpm:
  myStepper.setSpeed(15);
  // initialize the serial port:
  Serial.begin(9600);


}

void loop() {
  if (Serial.available() > 0) {
    // read the incoming byte:
   incomingByte = Serial.read();

    switch(incomingByte)
    {
      case'a':
      { 
       myStepper.step(-40);
  delay(1000);
      }
      break;
      case 'b':
      {
     myStepper.step(-20);
  delay(1000);
      }
      break;
      case 'c':
      {
         myStepper.step(0);
         
  delay(1000);
      }
      break;
      case 'd':
      {
        myStepper.step(20);
  delay(1000);
      }
      break;
      case 'e':
      {
myStepper.step(40);
    delay(1000);
      }
      break;
    }
  }
}

Hi,

You need to add a reference to System.IO into your C++ project

Something like this C# but as C++

Stackoverflow is your friend

Code
Select All
using System;
using System.IO.Ports;

namespace SerialPortTest
{
    class Program
    {
        static void Main(string[] args)
        {
            var p = new SerialPort(args[0], 9600, Parity.None, 8, StopBits.One);
            p.Open();

            Console.WriteLine("Sending ({1}) {0}", args[1], args[1].Length);

            p.WriteLine(args[1]);

            Console.WriteLine("Reading back");

            Console.ForegroundColor = ConsoleColor.Yellow;
            Console.WriteLine(p.ReadLine());

            Console.ResetColor();
        }
    }
}
