[Other Embeded program] PCmachine DL : 0: 单片机串行通信发射机采用串行工作方式，发射并显示两位数字信息，既显示00-99，使数据能够在不同地方传递。硬件部分主要分两大块，由AT89C51和多个按键组成的控制模块，包括时钟电路、控制信号电路，时钟采用6MHZ晶振和30pF的电容来组成内部时钟方式，控制信号用手动开关来控制，P1口来控制，P2、P3口产生信号并通过共阳极数码管来显示，软件采用汇编语言来编写，发射程序在通信协议一致的情况下完成数据的发射，同时显示程序对发射的数据加以显示。-Single-chip serial communication transmitters using a serial work, the launch and display the two-digit information, both show the 00-99, so that data can pass in different places. Hardware part of two main blocks, by the AT89C51 and composed of a number of key control module, including the clock circuit, control signal circuit, the clock used 6MHz crystal and 30pF capacitors to form the internal clock mode, the control signals used to manually switch to control, P1 mouth to control, P2, P3 I have a signal and, through a total of anode digital tube display, the software using assembly language to write, launch procedures consistent communication protocol in the case of complete data on the launch, at the same time show the process of launching the data to be displayed.
