摘要
研究了基于ST7920控制器的128×64中文字库点阵屏的开发使用方法,主要从图形点阵显示控制原理、液晶显示控制指令、液晶显示控制时序几个方面分析了液晶屏嵌入式应用的开发使用步骤,最终给出了一个单片机控制液晶显示的应用实例。
The using method of 128 × 64 dot matrix screen, which is based on the ST7920 controller and with Chinese word supporting, is studied in this paper. The development using steps of the LCD screen embedded application are discussed from the aspects of graphics dot matrix display control principle, liquid crystal display control instruction and liquid crystal display sequence control. Finally a LCD application with single-chip microcomputer control is given.
