以为用户开发的一套基于单片机的自动供水控制器为例,单片机是靠软件编程来运行的一种电子器件。本文讲述protel99se电子制图设计软件、proteusd电子仿真软件、keil汇编编译软件应用过程,可为从事单片机教学、开发、学习的同行们提供借鉴,可使学生更快地进入单片机的世界。 Taking a set of automatic water supply controller based on SCM developed by the user as an example, the SCM is an electronic device that runs by software programming. This article describes the protel99se electronic drawing design software, proteusd electronic simulation software, keil compiled compilation software application process, can be engaged in microcontroller teaching, development, learning colleagues to provide reference, allowing students to more quickly enter the microcontroller world.
