Im using an i/o card that came with an c dll, with included functions in order to read and write to 8 bit ports.
When i need to read from it from c++ i connect to the IO card and reads the value on it with the following function:
[CODE]
unsigned long DIValue = 0; // returned DI value
err = DI_ReadPort(cardID, DIPort, (U32 *) &DIValue);
if
(err!=NoError) {
//Error occurs !!
//ToDo : Handle error here
}
[/CODE]
Works fine.
Now if i want to use the IO Card dll in teststand instead, i get a problem. I connect fine to the card and can output to it, but how do i get the value from this function, which makes use of reference/cast, which gets placed in DIValue.
Ive tried using the reference/pointer options there is under c/c++ adapter when assigning parameters, but surely thats not enough.
