简易无线电遥控系统利用高频载频信号将调制信号经由发射端天线送出，在接收端经接收天线接收，再经过解调和解码恢复原信号用来控制发光二极管的亮灭。--Radio remote control system easy to use high-frequency modulated signal carrier frequency signal sent by the transmitter antennas, at the receiving end through the receiving antenna, and then through the demodulation and decoding to restore the original signal is used to control the brightness light-emitting diodes eliminate.--

Windows的资源管理器想必大家都用过，该程序的窗口一分为二，左边的窗口显示本机当前所有驱动器以及驱动器中的所有文件夹，当用户单击文件夹后，如果该文件夹下面还有子文件夹，则上层文件夹展开显示下级的文件夹；否则，右边的窗口显示选择文件夹下的文件。该文档提供了实现方法。-Windows resource manager must have all used, the procedure is divided into two one window. The left window shows the current machine and all Drivers Drivers of all folders when users click the folder, If the folder Read Documents folder, the folder launched upper and lower levels show the folder; Otherwise, the right to choose a window shows folder of documents. The document provides a method.

介绍uC/OS-II 在SkyEye上的移植分析.uC/OS-II 作为一个优秀的实时操作系统已经被移植到各种体系结构的微处理器上，也是目前较为常用的公开源码的实时内核。从这里入手学习嵌入式系统开发的基本概念，以及在 SkyEye 里构造一个可以运行的RTOS，能够使我们更深入地了解嵌入式开发的流程，在没有硬件的条件下也能对ARM的体系结构有个初步的认识。-on Phone/OS-II in the transplant SkyEye analysis .uC/OS-II as a excellent real-time operating system has been transplanted to various Architecture microprocessor, It is at present more commonly used open-source real-time kernel. From here start learning embedded system development of the basic concepts SkyEye Lane and the construction of an RTOS can run, enable us to a deeper understanding of embedded development processes, In the absence of hardware conditions can also ARM Architecture is a preliminary understanding.

微机报告 直流电动机斩波调速控制 以8088cpu为核心，扩展8253定时器/计数器，产生1ms（PWM的周期的方波），作为8259的IRQ7的中断请求信号，在中断程序中，由8255B口（PB0脚）输出PWM脉冲，经驱动单元输出驱动直流电动机（起码有高、中、低三个速度，甚至可连续调速）。-c++
