PWMPulseWidthSet不能改变脉宽值吗

JAME ORACAL
Intellectual 305 points


PWMPulseWidthSet(PWM1_BASE, PWM_OUT_0, Power_Full);

 PWMPulseWidthSet(PWM1_BASE, PWM_OUT_1, Power_Full);

 PWMPulseWidthSet(PWM1_BASE, PWM_OUT_6, Power_Full);

  PWMPulseWidthSet(PWM1_BASE, PWM_OUT_7, Power_Full);

这个函数单独调用不能改变脉宽吗

要怎样才能改变呢

    参考如下代码：

    //
    // Set PWM0 PD0 to a duty cycle of 25%. You set the duty cycle as a
    // function of the period. Since the period was set above, you can use the
    // PWMGenPeriodGet() function. For this example the PWM will be high for
    // 25% of the time or 16000 clock cycles (64000 / 4).
    //
    PWMPulseWidthSet(PWM0_BASE, PWM_OUT_0, PWMGenPeriodGet(PWM0_BASE, PWM_OUT_0) / 4);
