Xilinx Embedded Development source, the development of two very good examples

这是我无意中做的东西，还算可以，能够运行，希望能给初学者一点帮助1-This is what I inadvertently make things still can be able to run a little hope that I can help beginners 1

点阵单位通常都在任何一个的5x7或8x8的发光二极管矩阵。这些LED连接在矩阵，使得每个LED的阳极或阴极是常见的每一行中。换句话说，在一共阳极LED点阵单元，每个LED行将其所有阳极在该行的有线在一起。 LED的阴极将全部连接在一起在每列中。这样做的原因将很明显很快。一个典型的单一颜色的8x8点阵单位将有16个引脚，8为每个行和8为每一列。的原因的行和列都连接在一起，是尽量减少所需的引线的数量。如果不是这种情况下，一个单一的颜色的8x8点阵单元将需要65管脚，一个用于每个LED和一个共同阳极或阴极连接。通过布线的行和列在一起，只有16个引脚必需的。

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

自动售货机控制系统设计 要求： 设计制作一个自动售货机控制系统。 该系统能完成货物信息存储，进程控制，硬币处理，余额计算，显示等功能。 该系统可以管理四种货物，每种的数量和单价在初始化时输入，在存储器中存储。用户可以用硬币进行购物，按键进行选择。 系统根据用户输入的货币，判断钱币是否够，钱币足够则根据顾客的要求自动售货，钱币不够则给出提示并退出。 系统自动的计算出应找钱币余额、库存数量并显示。 -Vending machine control system design requirements: Design a vending machine control system. The system can complete cargo information storage, process control, coin handling, balance calculation, display and other functions. The system can manage four kinds of goods, the quantity and unit price of each in the initialization input, stored in memory. Users can use coins shopping button to choose. The monetary system based on user input to determine whether enough money, coins, according to customer requirements is sufficient Vending, coins were not given prompt and exit. The system automatically calculate the balance should be looking for coins, inventory number and displayed.
