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
