actually i did uart code before and its works .. but uart its very easy .. the port are easy to put in ucf for nexys3 not like the spi
Ok... pmod connnectors are multi purpose I/O connectors. You can map any signal to them like SPI signals. Choose a connector like PmodA and map the spi clock to T12 pin in example.
Look at the page 21 of this document to know which pin you may choose. https://www.xilinx.com/support/docu... Boards/XUPNexys3/documentation/Nexys3_rm.pdf
