数控插补程序，采用逐点比较法，插补任意圆弧和直线，通过设置脉冲当量，实现一定精度的插补。可见插补过程。-CNC interpolation procedures, point by point comparison, the interpolation of an arbitrary arc and a straight line, to achieve a certain accuracy interpolation by setting the pulse equivalent. Visib

采用Verilog语言，实现逐点比较法和圆弧插补(Using Verilog language, to achieve point by point comparison method and circular interpolation)

XY平面绘图仪，由单片机外接键盘输入信号，C52单片机输出控制信号，经过两个细分驱动器驱动X、Y两个电机移动完成图形绘制。单片机采用逐点比较法插补算法完成直线和圆弧的绘制，通过直线和圆弧的组合完成图形的绘制，最终实现了画线、画圆弧、画矩形、甚至可以实现复杂的图形绘制。(The XY planar plotter is input from MCU to keyboard. Output signal is controlled by C52 microcontroller. After two
