I'm not sure AWOL how your reply helps?
Lu_Ke, here in the forums we get many young and impatient people who expect to get answers to questions uttered in nearly unreadable gibberish and with no information about what they try to do, who expect the rest of the world to know the products they have on their workbench sometimes without even mentioning them. Your postings showed some but not all of the symptoms.
No to solve a problem, either you can do it on your own or you have to ask for help. And when asking for help, it's just as important as on your connections to get the protocol here right. You ask the wrong question, you get no answer or the answer to the question you asked and not you want to have answered. Getting this right is just as important as knowing how to solder or read a data-sheet.
AWOL's post was just a gentle reminder, that you your signals to get help were all wrong.
And yes, I am an old fart who's convinced that social graces aren't outdated.
