本人设计的用802051实现的键盘程序的识别代码。系统采用定时查询，防抖。如果监测到你一个代码，系统将键盘码输出。然后给我你个中断，用于提示中心机，读取键码。支持长按。-I designed keyboard with 802,051 procedures to achieve the identification code. System uses a regular query, Anti-Shake. If the monitoring to you a code, the system will output the keyboard code. And then give me interrupt you for the prompt Center machine, read the key code. Support the long press.
