  1. Hi everyone, it is probably a very stupid question. But i'm simply trying to toggle a LED(P1.0) by using the button S2(P1.1) which is on the launch pad of FR5969. but it is not wotking at all... #include <msp430.h> void main(void) { WDTCTL = WDTPW + WDTHOLD; // Stop watchdog timer P1DIR |= 0x01; // Set P1.0 to output direction P1REN = 0x02; ? P1OUT= 0x02; ? P1IE |= 0x02; // P1.1 interrupt enabled P1IES |= 0x02; // P1.1 Hi/lo edge P1IFG &= ~0x02; // P1.1 IFG cleared _BIS_SR(LPM3_bits + GIE); // Enter LPM4 w/interrupt } // Port 1 interrupt service routine #pragma
