To generate Video Signals?

Hi there,

I saw Rickard Gunee's site some info about how to generate tv signals with pic and sx.I wonder, Has anyone written some code to generate video signal? I read that pic is too slow to generate color signals, so B/W signals will be also good start point.Some code please?

Hello Analyzer,
I had a look to Rickard's Webpage and saw there are all infos to generate an video signal via PIC.
He provide a lot of useful documentations and the source code in asm.
I thing it could not sooo difficult to translate from asm to c, or?

Don't be worry about me, I had never made something like this.

Take a look to tis project:
http://www.web-ee.com/Schematics/PatternGenerator/patternb.htm
Is a video pattern generator with PIC. I tried and it works fine, the timing in the signal is no quite precise because of the low clock speed but it works fine, and the imagen looks fine in a tv. Is simple and functional.
You can test it in Proteus or some other simulation sofware before mounting the board if you want.
You can replace the MC1377 (if you can't get it) by another RGB encoder like AD714, CXA1645, etc.

Hmm,

Thanks for all replies.Rickard suggested a project that suits me veery much but it is again assembly :( I really can not understand asm code so i can not translate it to ccs c. It is a short code, how can i translate it? Can a friend translate it for us please? It is reaally important.

Thanks in advance
