Hi everyone, I'm new to programming in C++ and just wanted to connect to a USB TC-01 thermo couple using MinGW as compiler. connecting to the USB thermo couple seems to be tricky. I'm not used to load libraries and didn't manage to do so yet following some instructions but only understanding half of it. Is there an easy way for newbies to connect to the thermo couple? I just need the temperature, nothing else 🙂 I tried to copy something together (see code above) but I didn't manage to compile it because the nidaqmx library is missing. I didn't understand how to do it from this thread (some links not working, not understanding why it's a problem to load the dll), is there an easy instruction?
