Microcontroller programming function, concise and changeable, greatly shorten the development cycle, at the same time can make the elevator control system smaller and more powerful. The design and Simulation of some of the basic functions of elevator control system required, can pass through the button to select the floor, digital tube display realtime number of floors, the arrow indicates the LED lamp consisting of direction. This design pays more attention to get some knowledge into the design. Mainly includes the use of the STC89C52 chip, the use of C language pr
