Realization of Chinese menu interface based on graphic dot matrix LCD

Hao Su-chen

Abstract

The problem of how to realize the man-machine interface of Chinese menu based on the graphic dot matrix LCD (DEM12864P) is studied. The characteristics of LCD model (DEM12864P) are first analyzed. The relation of the DD RAM addressing and LCD dot matrix is explained, so are the display rules of Chinese characters and Chinese menu on the LCD model. Then the design of the cursor realization method and menu data structure based on the multi-task background is introduced; meanwhile the realization method of the design of the correlative software is also proposed.
