This book is self-published and is printed on demand. The original ISBN was generated in 2012, but if you purchase the book new from CreateSpace or Amazon you will get the new version, which was uploaded January 3, 2017. This book, now in its fourth edition (January 2017), is the third in a series of three books that teach the fundamentals of embedded systems as applied to ARM Cortex-M microcontrollers. This book specifically covers the TM4C and MSP432 microcontrollers; however, it could be used with any Cortex-M microcontroller. This third volume is primarily written for senior undergraduate or first-year graduate electrical and computer engineering students. It could also be used for professionals wishing to design or deploy a real-time operating system onto an ARM platform. The first book Embedded Systems: Introduction to the ARM Cortex-M Microcontroller is an introduction to computers and interfacing focusing on assembly language and C programming. The second book Embedded Systems: Real-Time Interfacing to ARM Cortex-M Microcontroller focuses on interfacing and the design of embedded systems. This third book is an advanced book focusing on operating systems, high-speed interfacing, control systems, robotics, Bluetooth, and the Internet of Things (IoT). Rather than buying and deploying an existing OS, the focus is on fundamental principles, so readers can write their-own OS. Embedded systems are a ubiquitous component of our everyday lives. We interact with hundreds of tiny computers every day that are embedded into our houses, our cars, our toys, and our work. As our world has become more complex, so have the capabilities of the microcontrollers embedded into our devices. An embedded system is a system that performs a specific task and has a computer embedded inside. A system is comprised of components and interfaces connected together for a common purpose. Specific topics include microcontrollers, design, verification, hardware/software synchronization, interfacing devices to the computer, real-time operating systems, data collection and processing, motor control, analog filters, digital filters, and real-time signal processing. This book employs many approaches to learning. It will not include an exhaustive recapitulation of the information in data sheets. First, it begins with basic fundamentals, which allows the reader to solve new problems with new technology. Second, the book presents many detailed design examples. These examples illustrate the process of design. There are multiple structural components that assist learning. Checkpoints, with answers in the back, are short easy to answer questions providing immediate feedback while reading. Simple homework questions provide more detailed learning opportunities. The book includes an index and a glossary so that information can be searched. The most important learning experiences in a class like this are of course the laboratories. More detailed lab descriptions are available on the web. Specifically for Volume 1, look at the lab assignments for EE319K. For Volume 2 refer to the EE445L labs, and for this volume, look at the lab assignments for EE445M/EE380L.6. There is a web site accompanying this book http://users.ece.utexas.edu/~valvano/arm. Posted here are Keil uVision projects for each the example programs in the book. You will also find data sheets and Excel spreadsheets relevant to the material in this book. The book will cover embedded systems for the ARM Cortex-M with specific details on the MSP432, TM4C123, and TM4C1294. Most of the topics can be run on any of these Texas Instruments LaunchPads. Ethernet examples can be run on the TM4C1294. Although the solutions are specific for the MSP432/TM4C families, it will be possible to use this book for other Cortex-M derivatives.

2.15 三相三线/四线应用 三相四线模式: HT7036采用三元件测量方法，合相功率计算公式为： 三相三线模式:HT7036采用两元件测量方法，合相功率计算公式为： 在三相三线模式下HT7036的B相通道不参加功率计量，只有A相和C相通道参与三相三线的测量。 但是HT7036可以将B通道的参数单独放出，只要在B相通道的电压与电流通道上加入相应信号，在三相 三线模式下仍可读取Pb/Qb/Sb/Urmsb/Irmsb/Pfb/Pgb参数，但是B通道的电压和电流通道上所加的信号不 会对三相三线的正常测量产生不良影响。 另外三相三线模式下.Urmsb寄存器可选择B通道输入信号，也可选择通过内部矢量方式直接计算 Uac有效值。 2.16 能量脉冲输出 两个高频脉冲输出CF1/CF2, 对应关系如下： 脉冲管脚 输出能量 CF1 全波有功电能 PF CF2 全波/基波无功电能 QF

《雷达系统分析与设计使用MATLAB 3rd Edition》是一本深入探讨雷达系统设计与分析的专业书籍，其配套代码提供了实践操作的平台，使理论知识得以直观化和具体化。MATLAB作为强大的数学计算和仿真工具，对于理解和实现雷达系统的各种算法至关重要。 雷达系统的基础在于信号处理，包括信号的生成、发射、接收以及信号处理。MATLAB代码可能涵盖了脉冲压缩、匹配滤波、多普勒处理等关键技术。脉冲压缩技术通过线性调频信号生成宽脉冲，提高距离分辨率；匹配滤波则利用已知信号形状最大化信噪比，提高目标检测性能；多普勒处理则用于分析目标的相对运动，提供速度信息。 雷达目标探测和识别是另一个重点。在MATLAB代码中，可能包含自适应阈值检测、恒虚警率(CFAR)检测等算法。自适应阈值检测根据背景噪声动态设定检测阈值，避免假警报；CFAR技术则确保在不同背景噪声下保持恒定的虚警概率，提高目标检测的可靠性。 再者，雷达系统设计还涉及目标参数估计，如距离、角度和速度的估计。MATLAB代码可能涉及到最小二乘法、最大似然估计等方法，这些方法用于从接收到的回波信号中提取目标参数，提高估计精度。 此外，波形设计也是雷达系统的重要部分。例如，线性调频连续波(LFM)、频率捷变(FM)等雷达波形可能在代码中有所体现，这些波形具有优良的特性，如距离分辨率高、多普勒处理能力强等。 MATLAB代码可能还包括了雷达信号的仿真，模拟真实雷达系统的工作流程，包括发射信号的建模、传播环境的模拟、接收信号的处理等。这有助于读者理解雷达系统在不同条件下的表现，并为优化系统设计提供依据。 在学习这本书时，配合MATLAB代码进行实践，不仅可以加深对理论的理解，还能提高解决实际问题的能力。通过调试代码，可以直观地看到算法的运行效果，这对于理论学习和工程应用都是非常有价值的。因此，这本书的配套代码无疑是学习雷达系统分析与设计的宝贵资源。
