| Abstract: | The principle of graphic dot matrix liquid crystal display module WGM-12832 and the instruction system of controller ST7920 were introduced in detail. The hardware interface circuit and the soft design between WGM-12832 and singlechip AT89S51 were expatiated concretely. Using graphic dot matrix liquid crystal module made the hardware structure simpler and software easier maintenance and expansion. The man machine interface with interface menu display and better combination of graphic and text was implemented. |
