嵌入式面试题:数据传输单工,半双工,全双工之间的区别

数据通常是在两个站（点对点）之间进行传输，按照数据流的方向可分为三种传输模式：单工、半双工、全双工。一、单工通信（simplex）单工通信只支持信号在一个方向上传输（正向或反向），任何时候不能改变信号的传输方向。为保证正确传送数据信号，接收端要对接收的数据进行校验，若校验出错，则通过监控信道发...

嵌入式数据传输及存储的C语言实现

各种类型的数据传输和存储就涉及到大小端的问题，首先要简单说下芯片的大小端问题，这里主要讨论Cortex-M内核。 M内核支持大端或者小端，实际应用中大部分内核都是小端。以STM32为例，全部都是小端，而且是芯片设计之初就固化...
