基于单片机和C语言的，步进电机加速减速匀速演示，希望方便大家(Based on SCM and C language, stepper motor acceleration and deceleration uniform presentation, I hope to facilitate)

飞思卡尔单片机锁相环程序，详细说明了锁相环的配置步骤以及计算方法(Freescale MCU PLL procedures, a detailed description of the PLL configuration steps and calculation methods)

旋转LED的实现,实现用单片机控制电机转速，采用无线供电方式哦(Rotate the LED, achieving MCU control motor speed, the use of wireless power supply oh)

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)

通过一个简单例子，说明C语言对于学习单片机的重要性，有助于新手的入门.(By a simple example to illustrate the C language for learning the importance of SCM to help novice entry.)
