I want to send data to my Arduino board using Visual Studio and C. I specifically need to use C since I am using ARToolKit to get markers and sending the data accordingly.
I was trying the code
#include<stdio.h>
#include<stdlib.h>
void main()
{
system( "MODE COM9: BAUD=9600 PARITY=n DATA=8 STOP=1" ) ;
FILE port = fopen( "COM9:", "wb" ) ;
printf("hello");
fprintf( port, "s" ) ;
fclose( port ) ;
}
but it is not getting compiled.
I just need to send data.
I understood from your post that you need to send data using visual studio not to write a program to flash or any other stuff. Here is an example i made for you on my machine it works sending the text test.
#include "stdafx.h"
#include <Windows.h>
#include <stdio.h>
#include <conio.h>
int _tmain(int argc, _TCHAR* argv[])
{
char test[] = "Hello";
HANDLE hDevice = CreateFile(L"COM2",GENERIC_READ | GENERIC_WRITE,FILE_SHARE_READ | FILE_SHARE_WRITE,NULL,OPEN_EXISTING,0,0);
if (hDevice !=INVALID_HANDLE_VALUE)
{
printf("Port opened! \n");
DCB lpTest;
GetCommState(hDevice,&lpTest);
lpTest.BaudRate = CBR_9600;
lpTest.ByteSize = 8;
lpTest.Parity = NOPARITY;
lpTest.StopBits = ONESTOPBIT;
SetCommState(hDevice,&lpTest);
DWORD btsIO;
WriteFile(hDevice,test,strlen(test),&btsIO,NULL);
CloseHandle(hDevice);
}
_getch();
return 0;
}
