include <msp430g2231.h>
unsigned int flag = 0;void main(){ WDTCTL = WDTPW +WDTHOLD; //STOP WDT // FLL_CTL0 |= XCAP14PF; //匹配14PF的负载电容 P1SEL &= ~BIT5; P1DIR |= BIT5; TACTL = TASSEL1 + TACLR ; TACCTL0 = CCIE; TACCR0 = 1748; TACTL |= MC0; _EINT(); while (1) { LPM0; }}
# pragma vector = TIMERA0_VECTOR__interrupt void TimerA0_ISR(void){ P1OUT ^= BIT5; flag++;}
我用flag作为标志,发现并没有进入中断,为什么啊?哪里错了?
