Carlos, I commend you on a very, very valuable obervation of how this forum really works.

As you mentioned, there are many advanced 8052 developers here that are more than happy to help answer questions if it appears that the person asking the question has done some amount of work or initial investigation.

I'm tempted to make your post "Required Reading" before new users post to the forum. :)
