currently I´m working with a programm, that is a software to a thermal camera. Its an opensource, so I can change anything I want.
There is an Alarm function, that triggers beeping after reaching some temperature. I have to change this function, so I could get a 5V trigger signal from my pc to some device, that stops heating etc.
I`ve done some research and found out, that might be possible with serial or parallel port. How could I use those in C++? Are there any turorials?
Thx in advance!
