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.

51上的RTOS，该RTOS为非占先式多任务操作系统，如果用户任务的最长执行时间小于 系统节拍时间，则本MiniRTOS要优于占先式TOS。因为本MiniRTOS占用资源小，RAM不超过20字节，程序空间只占为600多字节。-51 on the RTOS, the RTOS non-preemptive multitasking operating system, if the user of the longest task execution times smaller than system beats time, it is superior to the MiniRTOS Preemptive 200040. Because of the small resources MiniRTOS occupation, RAM no more than 20 bytes, procedures only for the space of more than 600 bytes.
