通过一个具体的实例——电脑自动打铃器来阐述嵌入式应用系统的工程设计方法。

嵌入式实时操作系统μCOS-II原理及应用(第2版)，该PDF为高清版本，并且有完整的目录，便于读者阅读、学习该操作系统。

本文设计的带共模反馈的两级高增益运算放大器结构分两级，第一级为套筒式运算放大器，用以达到高增益的目的；第二级采用共源级电路结构，以增大输出摆幅。

第三章 移植文件讲解 在第一章我们讲解了 UCOSII 在 STM32F407 开发板上的移植过程，第二章讲解了一下 Cortex-M3 和 M4 处理器的一些基础知识，本章我们就结合前两章内容讲解一下我们在 UCOSII 移植过程中的一些重要文件和我们移植 UCOSII 的过程中都做了那些工作，本章分为如下几部 分： 3.1 滴答定时器 Systick 3.2 os_cpu_a.asm 文件详解 3.3 os_cpu.h 文件详解 3.4 os_cpu_c.c 文件详解

针对传统甲烷浓度检测器体积大，不易在狭小空间操作的问题，设计了一种基于单片机的甲烷浓度检测器。系统程序设计基于实时多任务操作系统μC/OSⅢ进行开发，利用卡尔曼滤波算法进行数据处理。硬件部分选用意法半导体公司的STM32F407作为主控芯片，选用红外甲烷传感器Prime1采集气体中甲烷含量参数，同时采用豪威OV2640摄像头记录检测画面，通过SD卡存储模块记录检测数据。经过实地测试，系统检测精度为0.01%，具备实用价值。

可以快速查询μC/OS-II中的功能函数的产地参数，用法，及注意事项，很全面，所有函数按照字母排序

This book describes the design and implementation of mC/OS-II (pronounced "Micro C O S 2") which stands forMicro-Controller Operating System Version 2. μC/OS -II is based on μC/OS, The Real-Time Kernel which was firstpublished in 1992. Thousands of people around the world are using μC/OS in all kinds of applications such ascameras, medical instruments, musical instruments, engine controls, network adapters, highway telephone call boxes,ATM machines, industrial robots, and many more. Nu merous colleges and Universities have also used μC/OS toteach students about real-time systems.μC/OS-II is upward compatible with μC/OS (V1.11) but provides many improvements over μC/OS such as theaddition of a fixed-sized memory manager, user definable callouts on task creation, task deletion, task switch andsystem tick, supports TCB extensions, stack checking and, much more. I also added comments to just about everyfunction and I made μC/OS -II much easier to port to different processors. The source code in μC/OS was found in twosource files. Because μC/OS-II contains many new features and functions, I decided to split μC/OS-II in a few sourcefiles to make the code easier to maintain.If you currently have an application (i.e. product) that runs with μC/OS, your application should be able to run,virtually unchanged, with μC/OS-II. All of the services (i.e. function calls) provided by μC/OS have been preserved.You may, however, have to change include files and product build files to ‘point’ to the new file names.This book contains ALL the source code for μC/OS-II and a port for the Intel 80x86 processor running in Real-Modeand for the Large Model. The code was developed on a PC running the Microsoft Windows 95 operating system.Examples run in a DOS compatible box under the Windows 95 environment. Development was done using theBorland International C/C++ compiler version 3.1. Although μC/OS-II was developed and tested on a PC, mC/OS-IIwas actually targeted for embedded systems and can easily be ported to many different processor architectures.

本次设计的主要内容是：基于在stm32开发板上，将 μC/OS系统移植到stm32单片机上，然后再在该系统上编写超声波测距程序，最后通过LCD12864液晶显示屏来显示测量结果。

作为在 ARM Cortex-M 处理器上优化代码生成的 MATLAB-to-C 工作流程示例，白皮书说明了如何将生成的 C 代码从 MATLAB (R2014b) 移植到 KEIL μVision IDE (v5.12)。

借鉴RT-Thread思路，实现基于μCOSiii的AT指令代码，并附带详细使用说明。与MCU和模块基本没有耦合性，可直接用于绝大多数模块。
