pico 5000 series oscilloscope

[jack1]

Have tried the example files provided by Pico for labview and they work fine.

I want to scale the amplitude and timebase,.

Called the DLL's that were in the Pico SDK so I could call them in my program.

Version of Labview I am using is 2014 so saved the following files into the Labview, 2014,  'resources' folder from Pico SDK as detailed in their posts on this site:-

Ps5000a.dll

Ps5000aWrap.dll

Picolpp.dll

Fine so far....

Then created a 'call library function'  from Dll for ps5000aMinimumValue  using C:\Program Files\Pico Technology\SDK\lib\ps5000a.dll in my program followed by further icon from ps5000aMaximumValue from same location i.e. C:\Program Files\Pico Technology\SDK\lib\ps5000a.dll.

Program then runs but I get no values for Min value or Max values only trace.

Really frustrating because feel I am missing something obvious....

Thanks Jack

Post your code! It's very difficult to see if you 'missed something obvious' unless we can see what you've done. Preferably post a .zip containing the minimum amount of code that demonstrates what you are doing and the problem you are having.

Thanks for reply and usually would have provided a code snapshot but using DLL's and links thought a bit much.

 Problem was found to be using the DLL incorrectly and not stating a value in it first follwed by a pointer to that value.
