Hey thanks for the help dude. This page helped me in probing the right pin (Váš parťák ve světě tvoření | HWKitchen.cz). The only problem though is that there are only 54 I/O on the board so I don't know which pin like 63,64 on the actual controller are mapped to.
However from the link its clear where pins from 13,12,11,10,50,51,52 and 53 are mapped to
