说明：  单片机串行通信发射部分设计 我所做的是单片机串行通信发射机，它能显示数字信号，还能将信号发射出去。采用串行工作方式，能显示00-99的数字，用单片机89C51来控制，采用共阳极数码显示，软件部分由汇编语言编写。
(Single-chip serial communication part of the design of the launch I did was single-chip serial communication transmitter, it can display digital signals, but also the signal launch. Serial work, can show the number of 00-99, 89C51 MCU to control, using a total of anode digital display, the software prepared by the assembly language.)
