- at89c51下实现电子时钟源码,里面的按键(软件)消抖做得很好-at89c51 clock
key_timer
- 用定时器,扫描按键,比较好的解决了消抖问题,效率比较高-With a timer, scan button, a better solution to the debounce problem, more efficient
Project2
- 1、 硬件部分包括AT89C52、LCD1602和4个独立按键 2、 使用定时器0产生10ms的定时中断,作为时钟基准和软件定时器的基准。 3、 系统使用两个软件定时器Tkeyscan和Tdisplay。 Tkeyscan用来独立按键模块的定时扫描,每次扫描结合按键状态机的当前状态判断按键的有效性(消抖)及其时长(长按还是短按)。 Tdisplay用来定时激活LCD1602的显示(200ms一次,可自行修改)。 4、 整个系统在四种状态间流转:DISPL
