Using IVI with PAWS

•

5 In the doOpen() interface function, insert the following code below the line

Please insert your CEM driver code here:

hr = driver.CoCreateInstance(CLSID_Agilent34401);

if (FAILED(hr))

{

Display("\033[30;41m Bad return from

CoCreateInstance() method\033[m\n");

}

hr = driver->Initialize(CComBSTR("GPIB0::23::INSTR"),

VARIANT_FALSE,

VARIANT_TRUE,

CComBSTR("Simulate=TRUE"));

if (FAILED(hr))

{

Display("\033[30;41m Bad return from Initialize()

method\033[m\n");

}

Note:

doOpen is called for the first time when the run-time system loads the PAWS

project. If you intend to use non-ATLAS modules in your ATLAS code, subsequent

calls to doOpen will be made and you will need to execute the code above only

once.

6 To set the function for DC Voltage, the range to 1.5 volts, and the resolution to

1 millivolt, select the DMM.cpp file from the PAWS Project window.

7 In the DMM_Setup() interface function, insert the following code below the

line Please insert your CEM driver code here :

hr = driver->put_Function(Agilent34401FunctionDCVolts);

if (FAILED(hr))

{

Display("\033[30;41m Bad return from

put_Function(Agilent34401FunctionDCVolts)method\033[m\n"

);

}

hr = driver->get_DCVoltage(&pDMMDCVolt);
