Description

按键消抖方法及装置、包含机械键的设备、存储介质 技术领域
本公开涉及通信技术领域，尤其涉及按键消抖方法及装置、包含机械键的设备、存储介质。
背景技术
机械键在各种控制设备中被广泛应用，由于表明机械键被按下的按键信号是通过机械方式触发而产生的，因此按键信号总是由于键的机械抖动而出现毛刺。
对按键信号中出现的毛刺的一种处理方法是：判断键的状态，在判断键被按下后，延时一段时间，再次判断键的状态，如果键仍然为被按下的状态，才进行按键响应。
但上述处理方法有下面不足：一、因为需要延时后再次判断键的状态，所以不能立即进行按键响应；二、需要判断两次键的状态，增加了复杂度；三、即使经过一段延时，键的状态仍然有可能不稳定，从而造成误判。

具体地，当用户按压机械键、且该按压操作为有效操作时，触发机械键所在的电路产生按键信号。
根据需要，按键信号可以是高电平，也可以是低电平，但是本 公开不限于此。以下以机械键被按下而触发机械键所在的电路产生的按键信号是高电平为例进行说明。
此外，根据需要，可以在检测到所述按键信号后立即根据所述按键信号进行按键响应，即执行对应的操作。
步骤120，当检测到所述按键信号时，计时器复位并开始计时。
具体地，当检测到机械键所在的电路产生高电平时，计时器复位为0并开始计时。
步骤130，判断所述计时器的计时时间是否达到预设的时间阈值。
如果所述计时器的计时时间达到预设的时间阈值，则进入步骤140，如果所述计时器的计时时间未达到预设的时间阈值，则继续步骤130。
具体地，所述时间阈值为所述计时器的最大计时时间，其可以预设为检测连续的两次按键信号的最小时间间隔。本领域技术人员可以将所述时间阈值理解为用户连续两次按下机械键的最小时间间隔。如果所述计时器的计时时间达到预设的时间阈值，则说明之后机械键所在的电路将产生的高电平很大程度上为用户按下机械键而触发机械键所在的电路产生的按键信号，因此进入步骤140，如果所述计时器的计时时间未达到预设的时间阈值，则说明之后机械键所在的电路将产生的高电平很大程度上是毛刺信号，因此继续步骤130。
本实施例中，机械键所在的电路在所述按键信号之后且在所述计时器的计时时间达到预设的时间阈值之前产生的高电平均被视为毛刺信号。
此外，本实施例中，当计时器的计时时间达到预设的时间阈值时，计时器可以停止计时。
