Video output for microcontroller

[jk2001]

Hi,

I wanted to reply to thread240-155869 , but unfortunately it is closed, so that's why new thread ... I basically want a video (VGA) output from a microcontroller (PIC18 preferably). Someone recommended Parallax Propeller, but I have no experience with it nor I think it has enough power to do this job.

My idea is to use old ISA VGA card to do this job, but how complicated is it to initialize the card and set-up videomode from scratch (i.e. no video BIOS) ?

Another option would be something like

but it does only text mode (but has also keyboard interface integrated).

Ideas?

Thanks.

JK

I think that you should review the Propeller. It has eight parallel 32 bit processors running at more than 100 MHz each. Each processor has its own video generator. Much more power than you can cram out of the PIC18.

Drivers available for PAL and NTSC. You don't have to write a single line of code to get video. I love it.

I being a die hard PIC fan....

I'd have to agree with Gunnar.

Either one will work, the real problem is the large
amouts of data that needs to be transfered for any type
of quality graphics. I would look at the imx 27 or a
Davinci processor. Depends on the applications.

Here are some PIC links:

Micro VGA... interesting... but website looks very cheezy.
