Timer and Button Interrupts

Blinking LED swaps on Button click. Implemented using interrupts

<syntaxhighlight lang="c">

  1. include <msp430g2553.h>

__attribute__((interrupt(TIMER0_A0_VECTOR))) void CCR0_ISR(void) {

   P1OUT ^= BIT6 | BIT0;

}

__attribute__((interrupt(PORT1_VECTOR))) void BtnClick(void) {

   if( P1IFG & BIT3 ) {
       P1IFG &= ~BIT3;
       P1DIR ^= BIT6|BIT0;
   }

}

main() {

   WDTCTL = WDTPW + WDTHOLD;
   TACCR0 = 62500 - 1;
   TACCTL0 = CCIE;
   TACTL = TASSEL_2 + ID_3 + MC_1 + TACLR;
   P1REN = BIT3;
   P1DIR = BIT6;
   P1OUT = BIT6|BIT3;
   P1IES |= BIT3;
   P1IFG &= ~BIT3;
