摘要
介绍了一种可在单片机系统人机界面设计中替代传统按键的旋转编码开关,给出了转向与按键判断的方法和应用电路,并提供了用于菜单选择和数据输入的详细程序代码。
A rotary encoder switch with a button is introduced, which may be used in human-computer interface design instead of the traditional key in MCU system. The rotate direction and button press determine method and application circuit are given. The detailed program code for menu selection and data input is provided also.
