I wrote this book so that students, hobbyists, and engineers alike can take advantage of the Arduino platform by creating several PROJECTs that will teach them about the engineering process. I also wanted to guide the reader through introductory PROJECTs so that they could get a firm grasp on the Arduino Language, and how to incorporate several pieces of hardware to make their own PROJECTs. This book offers so much information on the Arduino, not just the basic LED PROJECTs but it offers different peripherals such as Ultrasonic sensor, the Xbox® controller, Bluetooth, and much more. This book also teaches the non-engineer to follow a process that will help them in future PROJECT (not just Arduino PROJECTs).

The main aim of this book is to present a unified, systematic description of basic and advanced problems, methods and algorithms of the modern con- trol theory considered as a foundation for the design of computer control and management systems. The scope of the book differs considerably from the topics of classical traditional control theory mainly oriented to the needs of automatic control of technical devices and technological proc- esses. Taking into account a variety of new applications, the book presents a compact and uniform description containing traditional analysis and op- timization problems for control systems as well as control problems with non-probabilistic models of uncertainty, problems of learning, intelligent, knowledge-based and operation systems – important for applications in the control of manufacturing processes, in the PROJECT management and in the control of computer systems.

一天学会用Allegro画电源板Allegro 由于其相对完善、强大的功能，一向被认为是较难学的画板软件之一，主要原因也是因为功能太多， 如果按 500 多页的出版教材来一一学是有点费时的，其实，如果只是用来画简单电源板的话，一两天就可以学会了， 没有很多命令要记，几乎要用的命令都可以从下拉菜单中找到且大部分都已以直观的图标按钮形式分布在软件主界 面上，即你可直接输入命令也可以从菜单中操作，也可从工具栏中点“按钮”，觉得哪种更方便就用哪种。该教程 只说画电源板用到的功能部分，使复杂工具变为简单、易学。如下图是一块用 Allegro 画的单面电源板。 ————本教材主要 for 从用 Altium Designer 和 PADS 转过来的工程师。完成板子的效率比 99SE 高得多。 一、 建原理图 *目的是用于生成网表导入 allegro 中布局。（习惯不需原理图和网表就能画板的工程师请跳到 allegro 篇） 1.1 找个盘比如 D 盘建个项目文件夹，里面再建两个文件夹，一个用于放电路原理图，一个用于放 PCB 文件， 尽量不要中文名。PS：原理图和 PCB 都放在同一个文件夹下也可以的，只是不好找不方便管理。 1.2 打开 Or CAD Capture CIS→File→New→PROJECT，在 name 一栏填电路图名称；在 Create a New PROJECT Using 一栏中选 PC Board Wizard;接下来一栏 Location 是选刚才建的文件夹路径然后点 OK 按钮。

标准外设库STM32标准外设库是一个固件函数包，它由程序、数据结构和宏组成，包括了微控制器所有外设的性能特征。该函数库还包括每一个外设的驱动描述和应用实例，为开发者访问底层硬件提供了一个中间API，通过使用固件函数库，无需深入掌握底层硬件细节，开发者就可以轻松应用每一个外设。Libraries 文件夹下面有 CMSIS 和 STM32F1xx_StdPeriph_Driver 两个目录，这两个目录包含固件库核心的所有子文件夹和文件，是代码移植的重头戏。CMSIS 文件夹存放的是符合 CMSIS 规范的一些文件， Driver 文件夹下是STM32F1标准外设固件库源码文件和对应的头文件，说白了就是将寄存器封装好的函数接口。PROJECT 文件夹下面有STM32F1xx_StdPeriph_Examples 和STM32F1xx_StdPeriph_Template 两个文件夹，Examples文件夹下是固件示例源码，Template文件夹下是工程模板。这些源码的学习对以后的开发学习非常重要。Utilities 文件夹下就是官方评估板的一些对应源码，可以忽略不看。根目录中还有一个固件库的帮助文档 stm32f10x_stdperiph_lib_um.chm文件。

首先下载软件，解压软件，安装在程序中找到SEGGER,选里面的J-FLASH，进入界面，刚开始的那个界面可以忽略，不用建PROJECT也可以；单击菜单栏的“Options---PROJECT settings”打开设置，进行jlink配置;正在General选项，选择“USB”，一般都是默认配置，确认一下即可;然后在CPU选项，选择芯片型号，先选择“Device”才能选择芯片型号，芯片型号，要根据你使用的芯片进行选择;在Target interface选项 里面选择SWD模式;首先Target里面选“Connection”连接目标芯片，然后 Target--Auto进行程序烧写;首先Target里面选择“Connection”连接目标芯片，然后 Target--Auto进行程序烧写.SEGGER J-Links are the most widely used line of debug probes available today. They've proven their value for more than 10 years in embedded development. This popularity stems from the unparalleled performance, extensive feature set, large number of supported CPUs, and compatibility with all popular development environments.

电学中的测量技术涉及范围非常广,电流测量在电学计量中占有非常重要的位置。如何精确地进行电流测量是精密测量的一大难题。传统的电流检测电路多采用运算放大芯片与片外电流检测电路相结合的方式,电路集成度很低,需要较多的接口和资源才能完成对电路的检测。本文把所有电路部分都集成在一块芯片上,包括检测电阻,运算放大器电路及模拟转数字转换电路,从而在电路内部可以进行电流检测,使电路更好的集成化。前置电路使用二级共源共栅结构的运算放大器,减小沟道长度调制效应造成的电流误差。10位SAR ADC中采用电容驱动能力强的传输门保证了模数转化器的有效精度。比较器模块采用再生锁存器与迟滞比较器作为基础单元组合解决精密测量的问题。本设计可以作为嵌入芯片内的一小部分而检测芯片中的微小电流1mA~100mA,工作电压在1.8v左右,电流检测精度预期达到10uA的需求。The measurement technology in electricity involves a wide range,and current measurement plays a very important position in electrical measurement.How to accurately measure current is a big problem in precision measurement. The traditional current detecting circuit adopts the combination of the operational amplifier chip and theoff-chip current detecting circuit, The circuit integration is very low, and more interfaces and resources are needed tocomplete the circuit detection.This topic integrates all the circuit parts into one chip, including detection resistance, operational amplifier circuit andanalog to digital conversion circuit. Highly integrated circuit makes the external resources on the chip more intensive,so that current detection can be carried out inside the circuit, so that the circuit can be better integrated. Thefront-end circuit of this PROJECT uses two-stage cascade operational amplifier and cascade tube to reduce the currenterror caused by channel length modulation effect. In 10-bit SAR ADC, the transmission gate with strong capacitivedriving ability ensures the effective accuracy of the analog-to-digital converter. Comparator module uses regenerativelatch and hysteresis comparator as basic unit to solve the difficult problem of precision measurement. This topic can beused as a small part of the embedded chip to detect the micro-current in the chip 1 mA~100 mA, the working voltageis about 1.8v, and the current detection accuracy is expected to reach the requirement of 10 uA.
