    I have 4 control boards with SPI outputs. Each board has one.
    Boards should be connected together and last one should be connected to
    pcb web server.

    Each board should send data over same web server and data should contain
    controller ID and some other stuff.

    Am stuck in this connection process.
    How to connect those boards together to get what I need ?

    The main problem is master / slave part.
    If the board is set as slave i can use one master ( web server ),
    so to get 4 boards together could be quite problem.

    In start each board should have own web server but thanks to shippment
    from china, non of those web servers that we have ordered has come.
    To be precise, they will come with 2 weeks delay, and i have 2 days to
    finish my project. That's why i have to make this with just one pcb web
    server.

    Yes they are built on this way.

    Please define "not working".

    What does your code look like ?
    More details on the boards would help.

  5. First you need to tell us what you mean by SPI, there is a million
    variations, three wire, four wire, etc..
