ECE 371 Microcontroller Interfacing Paper The description of “Debouncing” Name: Haomeng Sang Date: March 8, 2015 What is debounce and why use it Normally, Key switch usually used for mechanical elastic switch, when the mechanical contact is open or closed, Due to the elasticity of the mechanical contacts, a key switch when closed will not immediately be stably turned on and during disconnection does not suddenly disconnected. Thus at the closed and disconnected moment are accompanied by a series of jitter. Jitter is determined by the length of time of the mechanical properties of the keys. Key jitter can lead to misread a button repeatedly. To ensure that the CPU is only closed once
