Interfacing through SPI with Pmod

Former Member
Former Member over 12 years ago

I am trying to use the Zedboard to interface to a PMOD using JA1 connector and do a simple read/write via SPI. I have no found any simple tutorials for this. Can I get some help?

what I really want to do is do the least amount possible through XPS and just simply constrain my pins on the UCS and do everything else in the ARM C code...

(I also need a simple I2C interface and will post a separate thread for this)

    1, In XPS enable SPI in the XPS Zynq tab.
    2, Set IO to EMIO.
    3, Under Ports tab select ps7_0 and expand (IO_IF) SPI_0.  And change connected port to external ports.
    4, The SPI ports should be listed under "External Ports," now quits XPS, regenerate top level HDL.  You should see ports listed in top level HDL now.
    5, Constraint pins with UCS.
