Which dll functions to use

Post by cbfsystems »

The PicoScope dlls appear to export two sets of functions. One set corresponds to function names described in the Programmers Manual and the other set has the same names with "-2" appended to the end of the name. An example is "ps4000OpenUnitEx" and "ps4000OpenUnitEx-2". At least some of the LabVIEW examples on github use the functions with the "-2" appended. I'm not sure which to use. I found a mention of the "-2" in a topic titled, "Using Pico Technology Products with NI LabVIEW FAQs and Tips" under the section 9. How do I run the examples in 64-bit versions of LabVIEW? It says, "The function name will need to be re-selected - these should not contain an '@' symbol or have a '-2' suffix." I am using the 32 bit dll, not the 64 bit dll, so this advice is not applicable; it's just the only place I've seen any mention of the "-2" suffix. Why are there two sets of functions and what is the difference between them? Which should I use, and does the answer depend on the particular function?
