    About VGA interface to PIC.

    Hi guys, I'm planning to design a controller using PIC mcu to control a VGA display. Could you guys recommend me the mcu?

    ---------- Post added at 12:08 ---------- Previous post was at 12:01 ----------

    Is it that we just need 5 pins of signal (Red, Green, Blue, H-SYNC, V-SYNC) from mcu to drive the VGA display?

    Re: About VGA interface to PIC.

    You need to spec the content to the video, not just the Video interface.

    YOu might consider;
    Microchip PIC 16F84 VGA Output
    Atmel AVR VGA Text mode Output
    Atmel AVR graphics VGA output with SDRAM
    Atmel AVR and ISA VGA card
    Lattice MachXO CPLD/FPGA VGA generator
    µVGA.com VGA http://www.microvga.com/

    But I recommend you figure out how to advance order next Strawberry Pi, thats very popular but sold out.

    Like in this website, they use 5 signal only: http://www.alfersoft.com.ar/blog/201...single-button/
    What do you mean by spec the content to the video?
    Can I use 18F87k90?

    How do you want to control the VGA display?

    I don't have an idea. Could you recommend me the most common and simple one? I just want to display some text and some graph or chart.

    Re: About VGA interface to PIC.

    8 bit uC to VGA is a specialized design that is beyond the scope of this space.
    It would be easier to say get a $25 Raspberry Pi board. 1st learn how VGA interface works and understand it, test it and scope it.
