本软件是STM32f407芯片的ADC操作软件，采用DMA方式。我已经测验了在STM32f407开发板。为了STM32f开发，很有用的软件(This software is the STM32f407 chip ADC operating software, using DMA mode. I ve been testing the STM32f407 development board. In order to STM32f development, very useful software)

说明：  用stm32f103控制无源蜂鸣器播放音乐(Using STM32F103 to control passive buzzer to play music)

直流斩波变化的仿真和一些参考文献 可以学习一下(The simulation of dc chopper change and some references can learn )

交通灯控制程序 使用51单片机汇编语言编写

蜂鸣器发生实验，c语言编写，内容为音乐梁祝，蜂鸣器电路可以自制。(the speaker code )

一种占用很少资源的多事件操作系统，应用在M128上，极容易扩展到其他微控制器(A few more resources occupied events in M128 operating systems, applications, extremely easy to expand to other micro controller)
