Muhammad,
When anyone starts a new thread, this introduction is clearly shown on the entry form:

Before starting a new subject or posting your question...

Is there a recent existing thread on the topic? If so, please post your message as a reply to that thread
rather than creating a new thread.

Have you read the 8052 Tutorial?

Have you read the 8052.COM Frequently Asked Questions (FAQ)?

Have you searched 8052.com? Use the search tool on the left side of the screen.

Have you searched the message forum? Search Here:

Is this not clear?
When someone has obviously not made the slightest effort to see if the answer to their question is already at their fingertips, what response do you expect?

The object of a good education is not to give the student all the answers on a plate (that would be impossible!), but to equip the student to find answers for themselves!

eg, see this thread: http://www.keil.com/discuss/docs/thread1507.htm

"In my opinion, if you don't have time to ... provide the right direction, then silence is a good choice."

But, "use the 'Search' button" is the right direction!
