    Hi guys,
    I'm just planning to do a controller board with a PIC mcu on it that can drive a VGA display. I plan to just display text and simple graph or chart. I've found some info on the internet:

    But I just want an assurance from you guys, can a 8-bit PIC mcu able to drive the VGA display?
    Is it true we can drive the VGA display by just using 5 signals (RED, GREEN, BLUE, H-SYNC, V-SYNC)?

    Yes,it can be done to some extend.8 bits or 32 bits doesn't matters what matters is the speed ,more faster mcu you can use is more better.

    Good Luck

    Are the information we want to send for display encoded on the RGB signal?

    Have you seen the "maximite" processors?

    I'm not sure if they're from the PIC or ATMEL family but they have a VGA/composite interface included in the chip. among other ports of course. Cheap too.

    Roman Black has done this using a PIC18F452.
    His website is here:
    Click here:
    ...and scroll about halfway down the page to EasyPIC6 Project 3.
    You should find it helpful.

    Roman didn't provide any source code for it, but maybe if you ask him really, really nicely ... ;)
