90% of the responses are like "read the faq", "read the bible", so dont expect any help from this board.
And, if you valued OUR time as much as you evidently value YOURS, you would not ask questions to which the answer is readily found in e.g. "the bible".

Guiding you to "the bible" and other base documents will, eventually, make you leave mommas boob and go out on your own. If, for every question you have, you throw it out on the net and wait for the answer to come back you will learn NOTHING and never leave the nursery.

Thank you for mentioning "www.mikrocontroller.net", maybe the babies that refuse to grow up can go there.
