In Microsoft Visual Studio 2010 when I compile PS2000con.c it came up with a surprisingly relevant looking warning.

Against this line
short input_ranges [PS2000_MAX_RANGES] = {10, 20, 50, 100, 200, 500, 1000, 2000, 5000, 10000, 20000, 50000};

It reports
Warning 1 warning C4309: 'initializing' : truncation of constant value

Which seems fair and valid. 50,000 isn't going to fit into a signed short int on a 32 bit system. That's going to do ugly things to subsequent interpretation of the top voltage range.

I changed the definition to int and suggest Picotech do the same.

Hi

Well spotted. It will be changed in the next SDK release.

Older versions of Visual Studio don't seem to give a warning.
