MSP430的pwm波
单片机源程序如下:
- #include <msp430x14x.h>
- #include "Config.h"
- void setpwm1(int a){
- TACCR1 = a;
- }
- void setpwm2(int b){
- TACCR2 = b;
- }
- void main(void)
- {
- WDTCTL = WDTPW + WDTHOLD; // Stop WDT
- P1DIR |= 0xff; // P4.1 - P4.6 output
- P1SEL |= 0xff; // P4.1 - P4.6 TBx options
- TACCR0 = 13500; // PWM Period
- TACCTL1 = OUTMOD_7; // CCR1 resett // CCR1 PWM duty cycle
- TACCTL2 = OUTMOD_7;
- TACTL = TASSEL_2 + MC_1; // SMCLK, up mode
- setpwm1(1800);
- setpwm2(1800);
- _BIS_SR(CPUOFF); // Enter LPM0
- }
