This a command line app that was used in CSED’s session in CAT scope 10 , that’s used to control your parallel port output, added some useful functionality to it, like you don’t have to specify the whole value of the port to change only on pin’s value, that’s useful if you have many objects controlled by each pin.
I came to realize that I would finally use some of Digital Design fundamentals -in a high level language- to work in this app, like using AND(&) to set the pin off, OR (|) to set it on, and then XOR (^) to complement the value.
It’s a windows only app and the Dll used to interface with the parallel port is already provided.
