STM32 USB工程的文件分析

先介绍下我参考其他工程而建立的STM32 USB工程：

             


简单介绍下：Startup当然放置STM32的启动文件，CMSIS放置着STM32内核ARMCortex的内核文件，StdPeripheral_Driver目录里放置着STM32外设的库函数，这几个都是STM32工程必须的，这里不仔细讲诉，User Source里放着自己的应用代码，如main.c,stm32f10x_it.c等文件都放这里。USB-FS-Driver_Driver下放着USB的库，这里暂时不讲述，我重点想分析的文件在USB-User里，这个目录主要放着一些与USB库和用户相关的文件，起着USB库与用户之间的桥梁作用，文件如下图所示，该目录包含如下文件：
      


   接下去要分别分析下这几个文件：

hw_config.c：

这个文件主要是配置一些跟板载及系统相关的代码，比如说USB系统时钟配置，上拉电阻引脚及LED灯配置，还有USB的中断灯。主要的函数如下：

usb_des.c：

这个文件主要是定义了USB的一些描述符：分别是：设备描述符、配置描述符集合（包括接口描述符，HID描述符，端点描述符）、HID报告描述符、语言ID描述符、厂家的字符串描述符、产品的字符串描述符、产品序列号的字符串描述符。

usb_endp.c:

usb_Istr.c:

这个文件主要是每个端点对应的回调函数的注册；USB中断服务程序的处理，通过读取STM32 ISTR中断状态寄存器来判断是什么中断，并做相应的专断处理。
