    SPI communication between W5100 and PIC 18F4550

    Hello,

    Does anyone can tell me how to user a Wiznet W5100 with pic microntroller 18F4550.
    I'm about finishing my final year project

    Thank you

    Hi,

    usually the datasheet.

    It´s quite a general question, so what exactly do you need to know.

    SPI (hardware, timing) is well standardized, so it´s in most cases independent what SPI partners you use. For sure you need to send the correct bytes as described in the datasheets.

    Wiznet has published example software, e.g. for AVR and STM32. You can use it as a template for your PIC18 design, just replacing the low level SPI routines. For the hardware setup, you just need to know the SPI mode and supported clock speed.

    I just saw that Microchip has a W5200 PICtail, to be used among others with PIC18 development boards. So there's probably readymade software from Microchip.
