NI HSDIO 6556 module control using python



Anybody here who is currently exploring to control the NI 6556 module via python?


I've seen example files written in C for controlling/manipulating the module which we could control using python via ctypes but I'm currently stuck and don't know to make the coding as efficiently as possible


I've seen options to call on the HSDIO dll but I can't find the references on the functions to import.


any guidance is greatly appreciated. 🙂
