[SCM] 46GraphLED DL : 0: 通过在proteus中操作得知这个程序的作用是：显示图形。使我了解了数组、变量、子程序等的运用。此程序是通过开关键的控制来实现图形的显示形状，我们主要通过定时器来实现图形的显示间隔，按键的次数来显示索要显示胡和图形，使伙熟悉了P0、P1、P3输入/输出口的功能，以及74LS245芯片胡性能等。在程序开发中有一项编程风格很重要，那就是命名规则。一个变量的命名如果恰到好处，能够让人望文知意的话。会让别人在阅读你的代码时变得轻松，更加容易理解。这也在无形中提高了团队合作的效率。判断是按键还是干扰是非常有用的，它体现了一个系统的抗干扰能力。高低电平在瞬间的变换是很正常的，如果没有这条语句，系统很容易出错。 -Through the process of operation proteus function display graphics. I understand the array, variable, and use of such procedure. This program is through the open key control to realize that shape, we mainly through the timer to realize that the number of buttons interval, ask to show that hu and graphics, familiar with the gang P0, P1, P3 input/output function, and 74LS245 chip hu performance etc. In the process of developing a programming style, it s important to naming rules. A variable naming if properly, can let you know- text. You can let others in reading the code easier, more easy to understand. It also increased in virtually a team of efficiency. Judgment is a key or interference is very useful, it reflects the anti-interference ability of a system. High level in the instant transformation is very normal, if not this statement, the system is very easy to make a mistake.
