上面代码中释放与闭锁PWM的功能是由软件TRIP实现的。 以上三个函数基本在两电平或者三电平逆变器上用的比较多,除此之外PWM还有很多其他功能,接下来笔者慢慢列举。 PWM启动ADC 这是一个比较常用的功能,基本上如果使用DSP的片内ADC,大部分都会用PWM触发ADC ...
关注「Linux大陆」,星标公众号,一起进步! 最近在逛21ic论坛,看到几个帖子都在咨询如何控制单片机输出固定的数量的PWM脉冲,用于控制电机的转停,刚好前两天本人也需要该功能做测试,我是输出PWM给伺服电机驱动器,驱动器以位置模式工作,收到脉冲就 ...
Here is a circuit that will output a PWM wave good for varying the speed of a DC motor. Why is this not going to work? How would you fix it? The 555 timer can’t handle that type of load, and it is not ...
What is duty cycle? Duty cycle is defined by the percentage of high voltage duration in a complete digital pulse. If the duty cycle is 50%, then it will remain on for exact half the duration of the ...
