    Sample code available

    Posted by RKM on 20th Jan 2018

    Just wanted folks to know that there is some code available on the net. I have not used it personally but it certainly looks good: The comments indicate that this board is used for development.

    Example code needed

    Posted by Digilent Customer on 18th Mar 2016

    SPI communications with this board is quite complicated. Having some example code should do wonders in promoting this board.
