430单片机的基本例程。都已经调通可以使用。是新手上路必备

#include <msp430x14x.h>
#define f 1000

void main(void)
{ long int a;
  WDTCTL = WDTPW + WDTHOLD;             // Stop WDT
  P1DIR |= 0x02;                        // P1.1 output
  P1SEL |= 0x02;                        // P1.1 option select
  Set_DCO();                            // Set DCO
  CCTL0 = OUTMOD_4;                     // CCR0 toggle mode
  a=32768/(2*f);
  CCR0 = a;
  TACTL = TASSEL_2 + MC_1;              // ACLK, up-downmode
  
  _BIS_SR(LPM3_bits);                 // Enter LPM3
}
