单片机DS18B20测温功能模块　DS18B20数字温度传感器接线方便，封装成后可应用于多种场合，如管道式，螺纹式，磁铁吸附式，不锈钢封装式，型号多种多样，有LTM8877，LTM8874等等。主要根据应用场合的不同而改变其外观。封装后的DS18B20可用于电缆沟测温，高炉水循环测温，锅炉测温，机房测温，农业大棚测温，洁净室测温，弹药库测温等各种非极限温度场合。耐磨耐碰，体积小，使用方便，封装形式多样，适用于各种狭小空间设备数字测温和控制领域。.(DS18B20 digital temperature sensor MCU DS18B20 temperature measurement function module wiring convenience, packaged as can be applied to a variety of occasions, such as pipes, threaded, magnets, stainless steel package, a variety of models, LTM8877, LTM8874 and so on. Main changes its appearance depending on the applications. Package after the DS18B20 temperature measurement, can be used in the cable trench blast furnace water cycle temperature measurement, boiler temperature measurement, room temperature measurement, the agriculture greenhouse temperature measurement, temperature measurement of a clean room, the temperature measurement of the ammunition depot various temperature extremes occasions. Resistant to wear and touch, small size, easy to use package forms, suitable for a variety of the narrow space equipment digital temperature measurement and control field. .)

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)

对舵机的调试功能，通过多个舵机完成整个机器人的拼凑，进而完成机器人跳舞的任务。(The debugging function of the steering gear completes the assembly of the whole robot through multiple steering gear, and then completes the task of robot dancing.)

这是一份关于MSP430的C程序和课件，虽然不是很全面，但是对于新手还是够用的。(This is a report on the MSP430 C program and courseware, though not very comprehensive, but still enough for the novice.)
