how can make RGB signals with 8051 ????
Full pot for good system description.
I can only assume that you mean an RGB video signal for use with some form of video monitor (Maybe analog - VGA or maybe digital - DVI) but in reality you might mean talking directly to some form of LCD panel or producing RGB output with a LED matrix or, ...
If talking about RGB video for a normal computer display, the big problem is that such a display needs 1) Huge amounts of video bandwidth. An 8051 is normally not fast enough. 2) Huge amounts of video memory. An 8051 normally don't have enough RAM.
Maybe you should start by telling what you want to do - and why. The answer might be that you should not use RGB or you should not use an 8051 or ...
But pelease, avoid the tunnel vision. Not just a single sentence totally without context. Do write - preferably - several paragraphs of text describing as much as possible what, why, when, your knowledge, your tools, your allowed cost, school/hobby/commercial, ...
i need RGB for making tv pattern generator. i want to send my rgb to a mc1377 (composite video maker) and give composite from that.
First, do you understand how a TV pattern generator works?
If not, that is the first thing you need to study - completely independently of the 8051 or any other kind of microcontroller.
Once you understand how a TV pattern generator works - ie, what signals it needs to generate - then you can start to think about how you might implement that on a microcontroller in a general sense.
Then, when you have a general idea of what needs to be done, you can start to think about the specifics of how that might be achieved with an 8051.
