摘要
介绍由二片计数/定时器8253芯片及一片并行8255接口芯片组成的硬件直线插补器,它经过环型分配器及放大电路,同时控制二维(X向、Y向)步进电机实现快速直线绘制。它比利用软件实现的直线绘制法速度快,精度高。适用于数字控制的机械加工或绘图设备。
A kind of hardware circuit consisting of two 8253 programmable counter/timers and a 8255A programmable peripheral interface elements called straight line Inserting Compensator is introduced.By two Stepped-motors directed to X and Y contolled through a set of Circline-dividers and Driving-circuit,a straight line may be drawn with high speed.It has higher speed and is more accurate than software method,therefore more suitable for all kinds of digital machine and digital plotter.
