EAN条码字体的解码算法 经常发现用PB的开发人员在问为什么用EAN的字体打出来的条码扫描枪无法扫描 其实受EAN的编码规格的限制，EAN的字体是不能直接使用的，EAN13的编码规格就不 多说了，下面给出两个函数可把条码转换为EAN字体可识别的字符串(分别对应EAN13和EAN8两种编码)-EAN barcode font decoding algorithms are often found with the development of PB in the question why the fonts EAN bar code scanning to fight out of the gun can not scan a matter of fact by the EAN coding specification limit, EAN fonts can not be directly used, EAN13 of coding specifications do not say, and given the following two functions can be converted to EAN barcode fonts can be identified by the string (corresponding to two coding EAN13 and EAN8)

本世纪70年代，人们曾疯魔一种被称作“生命游戏”的小游戏，这种游戏相当简单。假设有一个像棋盘一样的方格网，每个方格中放置一个 生命细胞，生命细胞只有两种状态：“生”或“死”。-the 1970s, it has been a crazy magic known as the "Game of Life" small games, this game is quite simple. Suppose a chessboard like the same square grid, each box had placed a living cell, cell life only two states : "Health" or "die."

资源描述一个关于单片机led灯的实验，有Isis图和编程代码，刚入门的初级人士可以看看

注塑机生产过程的微机控制系统设计本系统设计是通过8255A并行端口A、B传输数据控制12个LED发光二级管的亮灭来模拟控制两台注塑机的生产过程。其中端口A和B分别对应1号和2号注塑机，每一个LED代表一个工序。编程语言采用BORLAND C++语言。-injection molding machine of the production process computer control system design of the system design through 8255A Parallel Port A, B transmission of data control 12 LED light emitting diode to the analog-to eliminate two injection molding machine control the production process. These ports A and B respectively counterparts on the 1st and the 2nd injection molding machine, each one represented an LED processes. BORLAND programming language using C language.
