Hallo,

Is it possible to transfer data from an GUI in visual studio to the mbed(LPC 1768) or is it impossible if you only use USB communication?

  1. include "mbed.h"

Serial pc(USBTX,USBRX);tx, rx

string size_cmd ="";

int main()

{

while(1)

{

if (pc.readable()) {

size_cmd=pc.getc();

pc.printf("data received");

/* Do some operations

  • /

} } }

Thx Titi

Assuming C# for GUI, see https://msdn.microsoft.com/en-us/library/system.io.ports.serialport(v=vs.110).aspx Use the serialport class. Make sure you open COMx: where x is the mbed port and that the baudrate is correct (same as mbed).

using System;
using System.Collections.Generic;
using System.Text;
using System.IO.Ports;
namespace Hello_CS_Serial_World
{
    class Program
    {
        static void Main(string[] args)
        {
        SerialPort _serialPort;
        // Create a new SerialPort object with desired settings.
        _serialPort = new SerialPort();
        //Defaults to ("COM1", 9600, Parity.None, 8, StopBits.One)    
        _serialPort.Open();
        _serialPort.WriteLine("Hello CS Serial World");
        _serialPort.Close();
        }
    }
}
