Hey,

I need to get the serial number from the Picoscope 2200 and I have tried using the property node.
When the node is run, there is an error 1097, which I believe is because I have not set it up properly.

After selecting the dll and get_Unit_Info function, here is how the parameters tab looks:

strlen: Numeric, 16bit int
handle: Numeric, 16bit int, pass Value
String: String, C String Pointer, minimum value - string_length
string_length: Numeric, 16bit int, pass Value

I wire up the handle, blank string constant, and a 256 int constant on the left
on the right I wire up a string output to an indicator

I am kind of new at property nodes
Am I doing something wrong?

Thanks
roastmeat

Your problem is probably the blank string constant.

Can you try creating a string, " ", containing as many spaces as the number of characters you expect to read back, and then pass this to the driver.
