    I doesn't get any sign of life from it...

    So maybe the SPI isn't set up properly or maybe it's just me that haven't ported it correctly.

    I've uploaded the code - keep in mind that it is a mix of my fully working LCD library/interface which I use for debugging, and the not working ported W5100 code!

    Download it here: http://elec.tkjweb.dk/SSD1963_W5100.zip

    Best Regards

    ''it doesn't go very well''

    What, exactly, do you mean by that?

    A complex system that works is invariably found to have evolved from a simple system that worked.A complex system designed from scratch never works and cannot be patched up to make it work.

    ''I doesn't get any sign of life from it... So maybe the SPI isn't set up properly''

    Have you checked with a scope that the clock is being generated?

    And any required chip select?

    And data on the data lines?
