Hi,
If you are still having issues with your code the following might help:
The following code might help:
loadlibrary 'pl1000.dll' 'pl1000Api.h' addheader 'picoStatus.h';
global data;
data.unithandle = 0;
data.maxValue = 0;
%%Open unit
% Open the unit - returns a handle to the device
[status_open, data.unithandle] = calllib('pl1000', 'pl1000OpenUnit', data.unithandle)
%%Maximum ADC value
% Obtain the maximum ADC value
[status_max_value, data.maxValue] = calllib('pl1000', 'pl1000MaxValue', data.unithandle, data.maxValue)
%%Close the unit
status_close = calllib('pl1000', 'pl1000CloseUnit', data.unithandle)
unloadlibrary('pl1000');
