摘要
本文主要介绍了大型绘图仪控制系统的设计,开发系统选用的是Motolora公司的PowerPC FSC823开发板,它是一种基于Linux的嵌入式系统。其中详细阐述了控制系统的硬件设计方案与软件设计思路,并具体描述了驱动步进电机的程序设计。与传统单片机控制系统相比较,本系统可以脱离上位机实现绘图和显示功能,并且能够从U盘和网络中读取绘图文件。
This paper mainly introduces the main train of thought of the design of the control system oft large drawing machine. The development system chooses Motolora's PowerPC FSC823 development board, which Is one of embedded system based on linux. Among these it expounds the hardware design project of the control system, and the way of thinking of software design in detail, and concretely describes the program design of driving stepping motor. Compare with the traditional monolithic control system, this system can escape from the superordinate machine to realize the drawing and showing function, and can read the drawing document from the U disk and network.
