CCS/CC430F6137: RTC Calender Mode

Intellectual 370 points
Part Number: CC430F6137

Tool/software: Code Composer Studio

Dear Sir,  

             I'm using CC430F6137 IC. I want RTC Calendar mode to use update date and time. already download your example header and source files from this linq (http://www.ti.com/lit/zip/slaa290) . I'm using ccs

compiler, when i will call incrementSeconds(); function inside timer interrupt, I will check debug code when reach this line (incrementSeconds();) code s stopped. where is my mistake. how to read Current date and Time

and send via UART. could you please solve my issue sir.

    Hi 

    Which demo code do you use?

    Could you share your code?

    How do you generate the 1 second interrupt?

    Best regards

    Gary

    Dear Sir, 

           I'm using timer and RTC library files, RTC library files download from  this linq (http://www.ti.com/lit/zip/slaa290). bellow code is 1 sec interrupt code. how to read date and time. please send soon sir. 


    #include <msp430.h>
    #include "RTC_Calendar.h"
    #include "RTC.h"


    extern void incrementSeconds(void);


    int main(void)
    {
    WDTCTL = WDTPW + WDTHOLD; // Stop WDT
    setTime( 0x12, 0, 0, 0); // initialize time to 12:00:00 AM
    P1DIR |= 0x01; // P1.0 output
    TA1CCTL0 = CCIE; // CCR0 interrupt enabled
    TA1CCR0 = 32768-1;
    TA1CTL = TASSEL_1 + MC_1 + TACLR; // ACLK, upmode, clear TAR


    __bis_SR_register(GIE); //  enable interrupts
    __no_operation(); // For debugger
    while(1)
    {
    P1OUT ^= 0x01;
    }
    }

    // Timer A0 interrupt service routine
    #if defined(__TI_COMPILER_VERSION__) || defined(__IAR_SYSTEMS_ICC__)
    #pragma vector=TIMER1_A0_VECTOR
    __interrupt void TIMER1_A0_ISR(void)
    #elif defined(__GNUC__)
    void __attribute__ ((interrupt(TIMER1_A0_VECTOR))) TIMER1_A0_ISR (void)
    #else
    #error Compiler not supported!
    #endif
    {
    incrementSeconds();
    // P1OUT ^= 0x01; // Toggle P1.0
    // __bic_SR_register_on_exit(LPM3_bits);
