    if(GpioDataRegs.GPADAT.bit.GPIOx==0)      //Check whether button pressed

    The above structure would give you the input GPIO state.

    Hello,

    Seconding Gautam's answer. Have you downloaded C2000Ware? It contains the header files that will allow you to write to/read from memory mapped registers the way Gautam described. It also has examples that demonstrate other peripherals on the device.
