Hello there,
I'm currently developing a windows console application on VS C++ 2017 to communicate with a digital multi-meter but when I try to run the code, I get the errors attached to this post.
The code used is following:
#include "stdafx.h"
#include "visa.h"
#include "stdio.h"
#include "stdlib.h"
int _tmain(int argc, _TCHAR* argv[])
{
ViSession vi; // Session identifier of devices
ViSession videfaultRM; // Resource manager session returned by viOpenDefaultRM(videfaultRM)
ViStatus errorStatus; // VISA function status return code
char buf[256] = { 0 };
//ViSession defaultRM, vi;
/* Open session to instrument */
errorStatus = viOpenDefaultRM(&videfaultRM);
errorStatus = viOpen(videfaultRM, " USB0::0x0957::0x0607::MY49002367::0::INSTR", VI_NULL, VI_NULL, &vi);
// If an error occurs, give a message
if (errorStatus < VI_SUCCESS)
{
printf("Unable to Open port; check address! %s\n", buf);
printf("Press Any Key to Continue\n");
getchar();
exit(0);
// Close the session
viClose(vi);
viClose(videfaultRM);
}
/* Send an *IDN? string to the device */
errorStatus = viPrintf(vi, "*IDN?\n");
/* Read results */
errorStatus = viScanf(vi, "%t", &buf);
// If an error occurs, give a message
if (errorStatus < VI_SUCCESS)
{
printf("Connected to instrument but unable to getID string... %s\n", buf);
printf("Press Any Key to Continue\n");
getchar();
// Close the session
viClose(vi);
viClose(videfaultRM);
}
else
{
/* Print results */
printf("Instrument identification string: %s\n", buf);
printf("Press Any Key to Continue\n");
getchar();
}
/* Close session */
viClose(vi);
viClose(videfaultRM);
}
Any idea how I can address these errors? Any feedback would be greatly appreciated!
Thank you in advance much for the attention
