The application of Character LCD Modules liquid crystal

The application of graphic liquid crystal display module in embedded system
Graphic dot matrix LCD module with small size, low power consumption, long life, low cost, it can Tsingtek lcd graphic display a variety of advantages, such as image and text information, so in all kinds of instruments and meters, electronic equipment, mobile communications, and has been widely used in household appliances [1]. In this paper, the author in the "portable power fault wave record device" in the project practice experience, focus on how to apply liquid crystal Character LCD Display module embedded DSP system man-machine interface problem, cooperate with each other in only four buttons, through software programming to realize the multilayer menu and dynamic waveform display. Software part compiled using C language, modular design, has a strong portability, can be directly applied to other embedded systems.
