【摘要】 延时消抖方法是嵌入式系统中常见的按键消抖方法,其通过延时程序跳过抖动态,该方法虽然可行,但既不具备实时性,也不具备可移植性。针对这种情况,提出了一种新的按键消抖方法,该方法通过一个累乘算法来有效识别按键抖动态和稳定态的区别,达到消除抖动影响的目的。实验结果表明,该方法不仅实时性强而且具备可移植性。更多还原

【Abstract】 Time-lapse method is a common method of shaking elimination of keystroke in the embedded system,it skips shaking-state via a time-lapse program,but this method has neither real-time performance nor portability.For this reason,a new method of shaking elimination of keystroke is proposed.It recognizes the difference between the shaking-state and steady-state via an algorithm of accumulated multiplication,so that it can eliminate the influence of shaking.The experimental results show that the method has both high real-time performance and portability.更多还原
