hi.
sorry but i put this message in another one and got anger message .and he did not move me.
i needt to display on a tv using an 8051. i saw some peron he did it on his calculater:a texas TI83PLUS. HES GOT IT IN BLACK AND WHITE.
ANYONE GOT ANy ideass how to do it and in color.it looks really cool idea.
So, what research have you done so far?
How about this for a starter: www.8052.com/.../
As I said before, it may be "cool", but it's not trivial...!
Don't assume that every forum have easy buttons where messages can be moved around. A lot of responsibility lies on the posters, to think before posting.
About TV signals: It is quite a lot harder to emit in color compared to emitting a monochrome image.
But you haven't even mentioned what TV system you have in your country. PAL, NTSC, SECAM, ...?
Google for the TV system. Then you should be able to find information about the timing required for the signal. Then you have to figure out how to time the horisontal and vertical sync signals. The processor speed will affect the possible horisontal resolution. A big problem is to avoid too much jitter in the image.
For color output, extreme timing is required, to get the TV to synchronize perfectly with the signal. I would not like to generate the color burst signal used (at least) by the PAL system. Remember that the analog color transmissions are extensions of monochrome transmissions, i.e. the color information if superimposed on a monochrome transmission.
