这是一个用51单片机系统仿真ucosii工作的protues电路 本系统包括扩展64k RAM的单片机系统和杨屹移植到51单片机的ucosii 系统 使用方法： 1.安装Protues7.4版，然后用protues打开protues 8051 simulation 文件夹 中的extern ram.DSN 文件 2.打开extern ram.DSN 后，双击单片机在弹出的窗口中的Program File 选项 中选择yy.hex文件。 (yy.hex其实就是yy文件夹中keil文档编译出来的hex文 件，yy文件夹是杨屹的ucos51 系统，用keil 2 可以打开) 3.在Clock Frequency选项中输入22.184M(杨屹的ucos51 用的是22.184M hz的单片机频率) 4.双击VTERM串口调试显示屏，在Baud Rate 选项中选择19200的波特率 5.保存，点击运行就可以看到经典的hello world 了。 (1. Protues7.4 version installed, and then open the protues folder protues 8051 simulation The extern ram.DSN file 2. Open extern ram.DSN, double-click the pop-up window of SCM in the Program File option, select yy.hex file. (yy.hex actually yy folder keil out of the document compiled hex files, yy folder is Yang Yi s ucos51 system, using keil 2 Can open) 3. In the Clock Frequency option to enter 22.184M (Yang Yi of the ucos51 using a microcontroller 22.184M hz frequency) 4. Double-click VTERM serial debug display, in the Baud Rate select 19200 baud rate options 5. Save, click Run you can see the classic hello world)

超声波测距模块扩展实验，使用超声波传感器，把数据结果显示在1602上。(Ultrasonic Ranging Module extension experiments using ultrasonic sensors, and display data results in 1602.)

同三维万能采集卡系列开发SDK包,包含例程等! (With three-dimensional universal capture card series development SDK package includes routines, etc.!)

本方案是基于富士通高可靠性单片机开发的锂电池电动螺丝刀，采用直流无刷电机作为核心，配合方波驱动以及闭环控制技术，实现电动工具的可靠运行。 技术参数 1）采用日本富士通MCU，性能稳定，抗干扰强，高可靠性； 2）直流18V输入（可兼容不同锂电池10V—36V）； 3）三相霍尔直流无刷电机驱动，转速高达25000转/分； 4）采用德国英飞凌高性能MOS/IGBT，驱动功率高达800W； 5）高亮LED照明，工作时点亮，不工作时自动熄灭； 6）采用智能控制技术实现待机（不工作时）功耗为 0 消耗； 7）通过软件实现软启动，启动时间可调整，瞬间（1S）达最高速； 8）具有过流保护、堵转保护、过压欠压保护； 9）带速度设置按键、正反转按键、调速开关； (The program is based on the Fujitsu MCU development of high reliability lithium battery electric screwdriver, brushless DC motor as the core, with the square wave drive and closed-loop control technology, power tools for reliable operation.)

基于单目相机和激光测距仪, 文章提出从一幅图像中识别出非合作目标物体上的矩形面,并提取出 4 个顶点坐标的特征提取方法,为位姿的测量提供必要的信息 提出以激光点为参考, 距离激光点最近的 4 条边 界为矩形面边界的判定准则,并根据激光点到直线的垂足和边界端点约束排除干扰线段 该方法能有效地判 定出矩形面且顶点定位准确,在空间机器人视觉伺服控制半物理仿真系统上得到了验证。(An approach to identi fying the rectangular plane of the object w i thout markers and extracting i t s ape- xes which are needed for pose measurement from an image is proposed in this paper. A cri terion is put forw ard that the edges w hich have the minimum distances around the laser point are regarded as the edges of the rec- tangular plane, and the interferent ial lines are eliminated according to the pedal between the laser point and the edge and two endpoints of the edge. The validity of the method is verified by experiments performed on a sem- i physical simulation system for visua- l serving cont rol of space robot s.)

基于STM32的双串口通信程序，能实现两个串口的收发，程序默认采用串口2接收数据，串口1发送(Based on the STM32 dual serial communication procedures, can achieve two serial transceivers, the program defaults to the serial port 2 receives the data, send the serial port 1)
