2018-05串行RS232通信接口_MAX232转接图

在我们的台式电脑上，有一个9针的串行接口，这个串行接口叫做RS232接口，它和UART通信有关联，但是由于现在笔记本电脑都不带这种9针串口了，所以和单片机通信越来越趋向于使用USB虚拟的串口和单片机通信，因此这一节的内容作为了解内容，大家知道有这么回事就行。我们先来认识一下这个标准串口，串口分为9针的和[详细]

2018-05这个单片机heX文件程序到底有多大

这个问题，相信很多单片机初学者都有遇到过，是什么问题呢？　　给大家举个栗子：　　　　先介绍一下常识：　　hex文件，就是我们要下载到单片机中的程序文件，而每一种单片机，都有一定的程序存储空间，一般就是多少K的Flash，例如STC15W408AS是8K的Flash，就是8K的程序存储空间，STC15W404AS就是4K的[详细]
