摘要：

介绍了几何最优直线插补算法的原理,并将其引入到点阵图形液晶显示中,给出数据转换实现方案及程序实现框图,并用C51高级语言实现.在要求对采样数据进行实时显示图谱曲线的单片机系统中,可将此方法作为底层函数库加以模块化.该方法最大偏差为半步,经验证，可满足较高的实时性要求,有很强的实用性和通用性.

Abstract:

The principle of the best geometrical way beeline interpolation was given, and the method to lattice graphics LCD display was introduced. The requirement for data conversion and program diagram was given, which can be realized with C51 advanced language. This method can be applied as a base function module in the MCU system of a real time display curve graph. In addition, this way has proved its practicability for the low deviation——half step and high real time performance.

Key words: best geometrical way; beeline interpolation; MCU; lattice graphics LCD
