    Hello Sefu,

    SYSCTL_RCGC2_GPION is not a valid define. On TM4C1231H6PGE to enable Port N you would need to use the SysCtlPeripheralEnable API with SYSCTL_PERIPH_GPION argument. Note that RCGCx register are legacy and not updated for new peripherals. Instead RCGCperipheral is the correct register to use.

    A word of caution: Do not use the DRM method to update register, as it will be deprecated breaking your SW
