    Hello!

    You can find examples of different configuration of GPIO pins for TMS320F28335 here

    ti\controlSUITE\device_support\f2833x\v133\DSP2833x_examples_ccsv4\gpio_setup\

    For example:

    // Make GPIO34 an input
    GpioCtrlRegs.GPBPUD.bit.GPIO34 = 0; // Enable pullup on GPIO34
    GpioCtrlRegs.GPBMUX1.bit.GPIO34 = 0; // GPIO34 = GPIO34
    GpioCtrlRegs.GPBDIR.bit.GPIO34 = 0; // GPIO34 = input

    Regards,

    Igor
