Newbie asks for advice on the timing problem of msp430 timer [Copy link]

#include  

void main(void) int i=0; WDTCTL =WDTPW+WDTHOLD; P2DIR = 0X01;P2OUT = 0X01; P3DIR = 0X01;P3OUT = 0X01; P1DIR = 0X01;P1OUT = 0X01; //Set P1 port direction to outputwhile(i<10) { TA0CCR0=32768; //1S TACCTL0=CCIE; TA0CTL =TASSEL_1+MC_1+TACLR; //ACLK, up counting mode i++; TA0CCR0=0; } __bis_SR_register(LPM3_bits); } #pragma vector = TIMERA0_VECTOR __interrupt void Timer_A0_ISR (void) { P1OUT ^= 0X01; } The requirement is to set a 6s timer. I used an LED light to test it, but I couldn't enter the timer interrupt. Please give me some advice.

Interrupt is not enabled

while(i<10) Oh my god, am I so casual?

Do not repeatedly initialize the timer

Do not add a while loop in the main function to count in the interrupt function. The problem has been solved.
