WINTEST Session
Start WINTEST . In the
devHandle field is the table
of preconfigured devices. If
no changes were made to the
factory default, the table
should include
IEEE and
Wave . The handle IEEE is
always in the device table for
interface-related commands.
As shown in the following
figure, select
Wave in the
devHandle field, then click
the OpenName button. The
number in brackets next to the
name
Wave changes from -1
to a positive number as the
command is executed and the
device is opened. The complete function call appears in the
Function Call field and the call also
appears in the executed command list.
In the executed command list, the number to the left in parenthesis, is the value returned by the function
call during execution. Generally, if the command completed successfully, the number is
0 , and if the
command caused an error, the number is -1 . For more information on the command return values,
refer to the “Section III: Command References” of this manual.
To clear the device named
Wave , select Clear under the
Bus menu item. Then, create
a new device using the
MakeDevice command under
the Device menu item. A
dialog box will pop up that
shows the C structure for the
required user input. In this
case, the name of the new
device is required. Fill in the
name and click OK. The
command and the returned
value will now be in the
command list, as shown in the
figure. Your new device now
appears in the
devHandle
field. Select BusAddress
under the Config menu item to
set the address of your newly created device.
As you fill in the pop-up dialog boxes, WINTEST uses your input to adjust the parameters in the
function call. These completed syntactically-correct lines of C code can be selected, cut and pasted
into your C editor at any time.
