Title Design of LCD Based on the 51 Series Single-chip Microcomputer
Abstract
Because of the nature of Chinese characters, showing Chinese in computer are always obstacles in our universal application of computer in China. With the development of MCU and display technology, furthermore, people are not satisfied with SCM system useing LED as display section, SCM control LCD display system now become the mainstream. This paper describes the use of the keyboard as input device, the 8051 microcontroller as the control equipment, LCD as display equipment. Make a LCD equipment that can shows number、characters、and dynamic display of Chinese characters .Through the keyboard input the display program addresses of Chinese characters displaying and display data.Then operating corresponding procedures and take the Chinese characters machine-code and Western ASCII characters out, then addressable memory for identifying the corresponding shown code Fonts or Chinese characters modes, extracted as a dot-matrix display information sent LCD shows. Use LCD display Chinese characters have flexible operation, results showed that effecting of display Chinese characters can be greatly improved.
