    AVR programmer Protocol

    Hi all

    1. Software part
    I would like to make a programmer to program AVR Like ATmega 328p
    So I need to study how programmer is working and what are the protocol and it rules
    Please advise good tutorials to study software part

    2. Hardware Part
    Also I am planing to do it using PIC Microcontroller for Hardware part


    Please recommend suitable MCU

    Thanks in advance

    Re: AVR programmer Protocol

    Hi,

    1)
    Each AVR datasheet contains all necessary informations how the chips can be programmed.

    Serial programming, parallel programming, timings, pin descriptions, voltage levels, protocol and so on.
    Additionally they have application notes for programmers, as well as hardware and software for different protocols....

    The manufacturer should always be the first address for such informations.

    2)
    First you need specifications.
    There are many programmers available. Form cheap to expensive. Why do you need another one?
    What are your requirements that others canīt fulfill?
    Donīt reinvent the wheel.

    But maye you have very special requirements, that really need a custom designed programmer.
    Then you should tell all about it. What is your target interface (DUT), what is your human interface (PC, cellular phone...) what operating system does it use?
    and so on.

    Re: AVR programmer Protocol

    Hi,

    it is so hard to understand datasheet
    Sooner or later you need to learn to understand datasheets. I see no way around this.
    A general statement "hard to read" can't be solved here, better ask a detailed question.
    Programming the AVR is not difficult. It's similarily difficult as writing text to a display..

    is there any other blog or website which is explaining about it more details
    I assume there are thousands. First place of information is the manufacturer, there are application notes.
