Hello
I have developed a small program that uses the NI-USB 6009 device to measure voltage levels.
This works very well, but since Im in need of measuring 14 voltage levels I bought the PCI 6010 device.
I can make measurements with the PCI 6010 device when using Measuremt and Automation explorer.
But when I try to use my program I will get the same result as when the USB device is not connected.
In my program I use :
for (i = 0; i<8; i++) {
measurementArray[i] = 0.0;
sprintf(devicepath, "Dev1/ai%d", i);
//printf("device: %s\n", devicepath);
DAQmxErrChk (DAQmxCreateTask("",&taskHandle));
DAQmxErrChk (DAQmxCreateAIVoltageChan(taskHandle,devicepath,"",DAQmx_Val_RSE,0.0,6.0,DAQmx_Val_Volts, NULL));
DAQmxErrChk (DAQmxStartTask(taskHandle));
//printf("Readback value before reading from DAQ device: %e\n", readback);
DAQmxErrChk (DAQmxReadAnalogScalarF64 (taskHandle, timeout, &readback, NULL));
measurementArray[i] = readback;
//printf("Readback value after reading from DAQ device %s: %e\n", devicepath, readback);
if( DAQmxFailed(error) )
DAQmxGetExtendedErrorInfo(errBuff,2048);
if( taskHandle!=0 ) {
DAQmxStopTask(taskHandle);
DAQmxClearTask(taskHandle);
}
if( DAQmxFailed(error) )
printf("DAQmx Error: %s\n",errBuff);is the function:
DAQmxCreateAIVoltageChannot available when using PCI 6010 ??
I have changed the Dev1 to Dev2 when trying to use my program.
Where do I set this names?
I changed them in Measuremt & automatation manager and it looked like that worked, at least for the USB device that I changed to Dev3.
How can I do to read data with my program from the PCI 6010??
Best regards
