    Still requires a lot of discrete components. 20+ resistors, 20+ caps, crystal, inductor, transformer. The transformer used in the 550IO is pricey. Wiznet's reference design varies somewhat from the transformer manufacturers data sheet also. A neat project might be a 5500-based pin-compatible replacement for the WIZ820IO.

    Finally heard back from wiznet today about the differences between the W5200 and new W5500. See attachment.

    I'm not sure I understand the new SPI protocol.

    Yeah I'm trying to wrap my head around the "Block Select Bit" portion. It seems that its just a shortcut to get to the registers for a given socket. So I think the deal is you select the Block [socket] then you offset into memory for the register you want.

    How do you control the transfer size? Just stop sending clocks when done? And is the bit order reversed?

    Seems like there are two options, fixed and variable. For variable it knows to stop when the chip select pin state changes.

    And is the bit order reversed?
    That seems to be true.

    Ugh I wish they would stop reinventing the wheel every time they release.

    Does somebody have a working W5500 driver (or maybe working spi read/write functions)? Im trying to get a webserver with W5500 working. Im also using an atxmega128a1 for that.

    I have a working W5500 server for MSP430. With few small changes, it can be used on other platforms.
