编写一个中断处理程序，在主程序运行过程中，每隔10秒响铃一次，同时在屏幕右上角开窗口显示信息“The bell is ring!” 以及时、分、秒。(prepared an interrupt handling procedures, the main program process, beep every 10 seconds once, in the upper right open window screen display information, "The bell is ring!" And, minutes and seconds.)

AD9826中文说明书 ，对于学习AD9826元件有很大的帮助。(AD9826 Discription in Chinese)

说明：  在STM32开发板上实现用光敏电阻控制LCD屏幕的亮度。(The brightness of LCD screen is controlled by photoresist on STM32 development board.)

基于stm32f103的5110显示屏驱动(5110 display driver based on STM32F103)

本例是用51单片机的键盘解码程序，亲试好用(This case is a keyboard with 51 decoding process, pro-test handy)

基于stm32f407的sd卡数据读写功能，源码数据(Based stm32f407 the sd card data read and write functions, source data)

诺基亚5110的驱动程序，主要用于单片机的开发，充当显示模块。(Nokia 5110 driver, mainly for single-chip development, act as a display module.)

三星S3C2440板子中配置时钟的程序，ARM ADS开发工具，初学的时候很实用。(Samsung S3C2440 board configured clock procedures, ARM ADS development tools, a novice when it is practical.)

利用单片机定时器产生高低电位各0.5毫秒的方波，该方波再经二阶滤波变成1K赫兹的正弦波，即为音频信号(To produce high and low potential of each 0.5 ms using SCM timer Fang Bo, the square wave and then by two order filter into 1K Hz sine wave, namely for audio signal )
