富士N系列可编程控制器PLC编程手册,介绍Flex N系列PLC的情况和其操作。-Fujitsu N Series Programmable Logic Controller PLC programming manual introduction of the Flex N Series PLC and its operation.

指南描述了如何实现小型且高速的中断驱动步进马达控制器-guide describes how to achieve the small size and high-speed interrupt-driven stepper motor controller

本原代码集是对计算机图形学的编程实践，包括画直线、反走样直线、画圆、画椭圆、画矩形、画多边形、矩形填充、多边形填充、3D变换、光照、贴图等。出于简化编程的考虑，许多地方指定了常数，未做通用处理。解压缩后建立gui16目录，在其下有原代码和工程文件。在gui16下建立release目录，其下有一可执行文件及其所须的位图及模型文件。如在release目录之外执行程序，必须复制所需位图及模型文件。内含-primitive code of computer graphics programming practice, including painting line, anti-aliasing straight Circle, painted oval, rectangular painting, drawing polygon, rectangle filling, polygon filling, 3D transformation, lighting, textures, etc.. To simplify programming for consideration, in many places designated constant, GM declined to handle. Decompress gui16 established after the catalog under the original code and engineering documents. Established in gui16 release directory, under which an executable file and the necessary bitmap, and model documents. If the release catalog implementation procedures, must copy the necessary bitmap and model documents. Intron
