Datasheet for programming the Microchip controllers?

    I can't find any instructions about how to program the microchip
    pic controllers in their relevant datasheets. Is it a standard
    procedure which applies to all of them, and where can I find

    I think if you browse the Microchip site there are some generic data sheets,
    including the programming instructions.
    Seem to remember finding and downloading them a while ago, but can't
    remember (of course) just where they were.
    Happy browsing ...

  6. Well, for PICs, there are a variety of techniques to handle --
    that is, if you want to actually design your own general purpose
    programmer. For example, one technique for the 16C5x series
    (the oldest type made available for hobbyist use, I think) and
    an entirely different approach for the PIC18's and an entirely
    different approach for the 16C84. And at least a few other ones
    in between.

    As to data sheets on how, there is AN589. But that only applies
    to the 16C84. There's AN750, on a PIC18C. There are guides on
    in-circuit programming (30277c, for example, and TB016 as well.)
    I believe some of the early paper application notes provide
    example circuits, as well. Anyway, look around. You might find
    schematics in the user manuals, programming specifications, and
    out on the web.

    And do look on the web for programmer schematics for PICs.
    There are several good ones out there. Or make your question
    more specific, because I don't think there is a single,
    comprehensive, one-stop shopping place for a datasheet on
    building programmers for the breadth of available PICs. But I
    could be wrong.

  7. There is no need to, there are many ready built programmers
    out there, some with schematics and software. The software
    is the larger part of the work b.t.w, and it's no project
    for a PIC beginner...

    They are on Microchip's site under the heading programming specifiction.
    They are a separate document from the data sheet.

    But unless you are simply interested in designing yet another PIC programmer
    you'd probably be better off utilizing others experience by putting together
    someone else's design and using existing software. Designs include my Trivial
    programmer series, Wouter's Wisp628, and Michael Covington's NoPPP. Software
    ranges from David Tait's FPP and icprog for Windows to pp06 and picprg2.3d
    for Linux based installations.

    Google is your friend from finding links to all of the above along with getting
    to a specific chip programming specifications.

    Take my advise, don't reinvent the wheel.


    If it's just a couple of PICs you need programmed up in a rush, I
    can do it for you at my regular rates. See

    Good hunting.

    You can find the microchip datasheet programming specifications on my site
    in the datasheets link.

    You need info about infrared remote protocols, 1 link:
