After having some trouble with scanf & printf (scanf receives 0x0D and convertes this to 0x0A) (printf attaches CR to \n)
i ask myself: where's the Sourcecode of all this function's? Printf & scanf sin, cos and all this stuff are library-functions. Can they be changed, it is useful to change them? Can i learn something for example how sin is computed?
Of course i've learned from this: now i use my own my_putchar & my_getkey when transmitting/receiving singele binary char's.
