防止机械抖动的三种可靠方法

Three Reliable Methods for Avoiding Mechanical Trembling

介绍机械开关在开关时抖动的三种处理方法,它包含软件处理方法和硬件处理方法,这些方法能可靠地消除机械开关抖动的影响,使微处理器能够快速、准确地处理这些机械开关的信号。

Three avoiding methods for the trembling of mechanical switches when they are turned on or off are introduced, including software and hardware processing method. These methods can reliably remove the effects of mechanical switches, making the microprocessor to deal with these signals of mechanical switches quickly and exactly.
