我所做的单片机串行通信发射机主要在实验室完成,参考有关的书籍和资料，个人完成电路的设计、焊接、检查、调试，再根据自己的硬件和通信协议用汇编语言编写发射和显示程序，然后加电调试，最终达到准确无误的发射和显示。在这过程中需要选择适当的元件，合理的电路图扎实的焊接技术，基本的故障排除和纠正能力，会使用基本的仪器对硬件进行调试，会熟练的运用汇编语言编写程序，会用相关的软件对自己的程序进行翻译，并烧进芯片中，要与对方接收机统一通信协议，要耐心的反复检查、修改和调试，直到达到预期目的。-Abstract:

With the rapid development of science and technology in recent years, the application of SCM is the deepening of the same time promote the traditional control detection technologies are increasingly updated. In real-time detection and automatic control of microcomputer application system, the microcontroller is often used as a core component to use only SCM knowledge is not enough, but also according to the specific hardware architecture hardware and software, to be improved.

Crossroads shuttle vehicles, pedestrians bustling Dealers lane, walkways, and orderly. Rely on to achieve this orderly order? Rely on automatic command system of traffic lights. Traffic signal control. The system uses the MSC-51 series of microcontrollers the ATSC51 and programmable parallel I/O interface chip 8255A-centric devices to design a traffic light controller, realized according to the actual traffic flow through the 8051 P1 outlet red, the green light to kindle the function　traffic light cyc
