51单片机通过外部中断读取标准的PS2串行键盘，并在1602液晶上显示-51 MCU via an external interrupt to read a standard PS2 keyboard, serial, and in 1602 LCD display

C51 的串口通讯，通关中断方式接收和发送数据-C51 serial communication, and customs clearance to receive and transmit data interrupt

串口商业程序范例： 接收和发射均采用中断模式，并且具备接收发射数据缓存功能，单片机可以方便的用状态机处理串口信息，商业程序最理想的处理方法，集成开发环境TKStudio。-Serial Business Program Example: Are used to receive and transmit interrupt mode, and have the receiver transmit data buffer function, the microcontroller can
