CCS/MSP430FR5994: msp430fr5994.h version 1210 (CCS 10.1.0) is missing Digital I/O Base Address Definition

Hi, Eddie,

I can run my FR5994 Launchpad well with P1.0 LED blink. 

In the header file MSP430FR5994.h, the definition is different from previous CCS version. The PORT1,2,3.. are defined separately with the based address.

Please double check your header file. But I am running the code example on CCS10.0.0. Do you see and difference from CCS10.1.0?

Thanks,

I'm sorry, I should have been more specific. I was trying to use GPIO_enableInterrupt() from driverLib. This function worked with the header from version CCS 9.1 but the function stopped working when I migrated to CCS10.1.0.

void GPIO_enableInterrupt(uint8_t selectedPort,
                          uint16_t selectedPins) {
    uint16_t baseAddress = GPIO_PORT_TO_BASE[selectedPort];

    #ifndef NDEBUG
    if(baseAddress == 0xFFFF)
    {
        return;
    }
    #endif

    // Shift by 8 if port is even (upper 8-bits)
    if((selectedPort & 1) ^ 1)
    {
        selectedPins <<= 8;
    }

    HWREG16(baseAddress + OFS_PAIE) |= selectedPins;
}

When my parameters were GPIO_PORT_P6 and GPIO_PIN3, baseAddress would return 0xFFFF, which is obviously a problem. From gpio.c :

static const uint16_t GPIO_PORT_TO_BASE[] = {
    0x00,
#if defined(__MSP430_HAS_PORT1_R__)
    __MSP430_BASEADDRESS_PORT1_R__,
#elif defined(__MSP430_HAS_PORT1__)
    __MSP430_BASEADDRESS_PORT1__,
#else
    0xFFFF,
#endif
#if defined(__MSP430_HAS_PORT2_R__)
    __MSP430_BASEADDRESS_PORT2_R__,
#elif defined(__MSP430_HAS_PORT2__)
    __MSP430_BASEADDRESS_PORT2__,
#else
    0xFFFF,
#endif
#if defined(__MSP430_HAS_PORT3_R__)
    __MSP430_BASEADDRESS_PORT3_R__,
#elif defined(__MSP430_HAS_PORT3__)
    __MSP430_BASEADDRESS_PORT3__,
#else
    0xFFFF,
#endif
#if defined(__MSP430_HAS_PORT4_R__)
    __MSP430_BASEADDRESS_PORT4_R__,
#elif defined(__MSP430_HAS_PORT4__)
    __MSP430_BASEADDRESS_PORT4__,
#else
    0xFFFF,
#endif
#if defined(__MSP430_HAS_PORT5_R__)
    __MSP430_BASEADDRESS_PORT5_R__,
#elif defined(__MSP430_HAS_PORT5__)
    __MSP430_BASEADDRESS_PORT5__,
#else
    0xFFFF,
#endif
#if defined(__MSP430_HAS_PORT6_R__)
    __MSP430_BASEADDRESS_PORT6_R__,
#elif defined(__MSP430_HAS_PORT6__)
    __MSP430_BASEADDRESS_PORT6__,
#else
    0xFFFF,
#endif

Since __MSP430_HAS_PORT6_R__  is no longer in msp430fr5994.h, __MSP430_BASEADDRESS_PORT6_R__ becomes defined as 0xFFFF. 

In other words, the msp430fr5994.h in CCS10.1.0 becomes incompatible with gpio.c in driverLib of MSPWare.

I looked at the header included with TI GCC and it seems to have a similar problem. The version from the latest installation (9.2) has just three HAS_PORT symbols defined while the 4.1 and 8.3 versions have twelve defined.

Hi, Eddie, 

Thanks to report this. I will ask software expert about this. 

Thanks,
