Where the hell to start? Where did you guys learn these codes, what they do, why and how to write the bin files. Is there books I might pick up at books a million that could shed light on this type of programs? It seems the more I read the more confused I get. I guess I cannot see the "big picture" of how it all goes together. That might make it all make more sense. All computer programs have a start and an end. Are the "programs" closed or open loops? I would think that for performance based rather than economy performance you'd want it to always do the same thing every time thus closed loop. Any help would be appreciated.
