C2000 SPI İnit for ENC28J60

Hi,

Is there anyone who interface a C2000 series DSP with a SPI-ETH module of Microchip (ENC28J60). By the way my MCU is F28335.

I need to initialize this SPI-ETH IC via SPI. If so I wonder does anyone works on this subject previously ?

    Hi Onur,

    Getting info on this specific interface would be difficult but do search this forum thoroughly. You can try building/modifying the SPI example code according to your requirement as Step1.

    Regards,

    Hi Onur,

    It looks like the ENC28J60 supports a standard SPI interface:

    Note that the ENC28J60 will receive the SPICLK from the 28x therefore the 28x SPI will be configured fro MASTER mode.  You can also use the 28x SPISTE signal for the ENC28J60 CS.  For receiving the interrupt signal you may want to use one of the XINT pins.

    As Gautum pointed out, the SPI example code is a good starting point.

    Thank you for the responses.
    Actually I know the SPI interface, and already communicate with other ICs. As far as I know TI doesn't have such an IC for Ethernet so I just wonder if anybody interface this ENC28J60 with F28335 and want to know the performance, any problem, experience etc.
    It has a detailed datasheet and generally used with PIC with their already developed Ethernet libraries.
    Anyway, thanks for your interest.
    Regards

    We have MCUs with the Ethernet Controller and PHY integrated, link.  

    For a more direct comparison look at the DP83867IR.
