Note, I've seen: How fast is too fast?, and What to do when loading is TOO fast? so I want to clarify the non-duplicity: I'm not asking about the animations, but more or less about the application in general. There are no animations for this apart from the uncontrollable browser reactions, so the...
I have a question. I'm working with STK500 device to implement C4Connect game using minimax Algorithm.
I build my project with C++ for desktop and work fine, but now that I have transferred my code to my STK500 device doesn't work fine. I suppose that is for the data that it must process.

I noticed that fail bits are set for each function however not every problem sends a fail bit so I thought this would be a good exercise to try and target two user input errors: 1.) The user enters...
