STM32F4(BUZZ)

GitHub仓库：http://github.com/XinLiGitHub/STM32F4xx_BUZZ_Example
PS：博文不再更新，后续更新会在GitHub仓库进行。

   在实际的项目开发过程中，常常会遇到硬件电路的修改，然后修改的部分就需要修改驱动程序。想这样需求该来该去是程序员们最烦闷的事情（重复劳动痛不欲生啊~）。为了避免或减少重复劳动，就需要在程序的架构上下功夫。接下来以最常见的无源蜂鸣器驱动程序为例，进行程序结构设计。

1，开发环境

   1，固件库：STM32F4xx_DSP_StdPeriph_Lib_V1.8.0
   2，编译器：ARMCC V5.06
   3，IDE：Keil uVision5
   4，操作系统：Windows 10 专业版

2，程序源码
   BUZZ.h文件
