摘要
点阵液晶显示模块在工业控制设备中正逐步得到广泛的应用,本文针对320×240点阵液晶显示模块,在确定直角坐标轴以及显示点地址与坐标(Xh,Yh)之间相互转换关系的基础上论述了应用微处理器绘制直线的方法,给出了其指令的组成结构,推导出计算方法,讲述了绘制曲线的方法。
Dot-lattice-LCD has widely been applied in control equipment for industrial.In this paper,a right angle coordinate is designed,and converting showing dot address to the coordinate value (Xh,Yh)each other is argued.A technique of drawing curve is dissertated and structures of the drawing curve instruction are designed,and its numeration methods are exported,acooding to the determinate coordinate.
