#include <msp430g2553.h>
void main(void)
{
WDTCTL = WDTPW + WDTHOLD; // Stop watchdog timer
P1DIR |= BIT0; // Set P1.0 to output direction
P1IES |= BIT3; // P1.3 Hi/lo edge
P1IFG &= ~BIT3; // P1.3 IFG cleared
P1IE |= BIT3; // P1.3 interrupt enabled
_BIS_SR(LPM4_bits + GIE); // Enter LPM4 w/interrupt
}
// Port 1 interrupt service routine
#pragma vector=PORT1_VECTOR
__interrupt void Port_1(void)
{
if (P1IFG & BIT3)
{
P1OUT ^= BIT0; // P1.0 = toggle
P1IFG &= ~BIT3; // P1.3 IFG cleared
}
}
这段码不是P1.3控制P1.0的吗？怎么按了控制键后有时会熄灭不了呢？是控制沿有问题吗？ |
