LS16绘图机的软件设计

The Software Design of LS16-Plotter

本文阐述了LS16绘图机软件设计中的思想原则、实施方法与技巧.文中提到:电机相关模块用软件办法存贮电机三相六拍状态表,并通过软件操纵两个指针的上下独立移动,控制电机作任意组合方向运动;笔态设有笔的抬、落和翻转笔态模块;笔画方向设有八个最基本的笔画运动方向的处理;直线段插补偏差计算的改进算法和决策表.

The paper (?)esents the principle,implementa-tion and technique on the software design of LS16-plotter.In the paper,we deal with using softwareto store the 3-phase.6-beat state list in module relativeof electrical machine,operating the independentmovement of two needles to control electricalmachine movement in arbitrary direction.In theplotter.the pen state can set up raising,dropping andturning over.and the pen can move in 8 essentialdirections.In the paper,we also put forward themodified algorithum about straight segment inter-polation deviation calculation and the decision-making list.
