It all started rather innocuously. I walked into Dr GT Murthy’s office one fine day, andchanged my life. “Doc” was then the General Manager, Central R&D, of a very largeelectrical company headquartered in Bombay. In his new state-of-the-art electronics center,he had hand-picked some of India’s best engineers (over a hundred already) ever assembledunder one roof. Luckily, he too was originally a Physicist, and that certainly helped me gainsome empathy. Nowadays he is in retirement, but I will always remember him as athoroughly fair, honest and facts-oriented person, who led by example. There were severalthings I absorbed from him that are very much part of my basic engineering persona today.You can certainly look upon this book as an extension of what Doc started many years agoin India … because that’s what it really is! I certainly wouldn’t be here today if I hadn’t metDoc. And in fact, several of the brash, high-flying managers I’ve met in recent years,desperately need some sort of crash course in technology and human values from Doc!

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。

一种通用微型飞行控制器设计 105页摘 要 微小型无人机(Micro/Mini UnmannedAerial Vehicle,M【,AV)在现代军事和国民经济中发 挥着越来越重要的作用。飞行控制器是无人机系统的核心,它自动采集无人机的各种飞行参数, 输出舵面/油门指令以控制无人机的姿态和轨迹,使无人机能在没有人工操纵干预的情况下自主 飞行,完成预定的任务。因此,研制高性能的飞行控制器对改善无人机的飞行性能以及提高任 务完成效率都具有重要的意义。 本文着重研究一种通用微型飞行控制器(General Micro Flight Controller,GMFC),以适用 于小型/微型固定翼飞行器、旋翼飞行器、飞艇以及移动机器人的控制。论文的主要工作涉及 GMFC的硬件设计与软件实现,具体内容包括: 1)分析了微型飞行控制器在国内外的研究现状和发展趋势,根据任务需求和设计指标确定 一种通用型、微型化、低功耗、高性能、低成本的嵌入式微型飞行控制器的整体方案。 2)设计了基于ARM的通用微型飞行控制器的硬件系统,包括主控模块、惯性测量单元、 静压高度计、遥控信号接收单元、数据通信模块、电源模块、附加传感器模块等;完成了整个 控制器的PCB制作以及对所有电路的调试工作,使得系统运作正常。 3)研究了基于卡尔曼滤波算法的姿态参考系统,并对姿态参考系统的静态性能和动态性能 进行测试。 4)设计了小型四旋翼飞行器本体平台并对其进行动力学建模仿真; 5)在此基础上,结合四旋翼飞行器试验平台设计了飞行控制律,开发了GMFC的软件系 统,并开展物理实验验证。

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.
