LCD display technology based on AT89C2051
abstract:
Microprocessor, which is called micro controller unit, has a series of advantages such as high level of integration, strong function, high reliability, small size, low power consumption, easy to use, low in price and so on. At present, the application of microprocessor has been infiltrated into people’ work and live in every corner. In this paper, the main performance parameters and functions of AT89C2051 is introduced, as well as liquid crystal display LCD working principle, performance characteristics. The system focuses on the hardware circuit design and software design, application of 4 × 4 keyboard input, C language programming through the use of single-chip control, finally displayed in LCD.
