【HAL库每天一例】第059例：USB-SD卡模拟U盘

haohao663 提问时间：2016-7-3 11:50 /

【HAL库每天一例】系列例程从今天开始持续更新。。。。。
我们将坚持每天至少发布一个基于YS-F1Pro开发板的HAL库例程，
该系列例程将带领大家从零开始使用HAL库，后面会持续添加模块应用例程。
同样的，我们还程序发布基于HAL库的指导文档和视频教程，欢迎持续关注，并提出改进意见。
例程下载：
资料包括程序、相关说明资料以及软件使用截图

【1】例程简介
  STM32F103ZET6内部集成USB控制器，在无需外接芯片可以做为USB从设备。

【2】跳线帽情况
******* 为保证例程正常运行，必须插入以下跳线帽 **********
丝印编号    IO端口    目标功能引脚       出厂默认设置
  JP1       PA10       TXD(CH340G)       已接入
  JP2       PA9       RXD(CH340G)       已接入
  JP3       PB0          LED1             已接入

【3】操作及现象
  将一张小于32G大小的Micro SD卡插入到开发板上的SD卡槽内，使用开发板配套USB线连接
到开发板标示“USB协议”字样的MIMI USB接口，打开开发板电源开关。下载完程序之后，
在电脑端会发现“可移动硬盘”并自动安装驱动，然后在“我的电脑”中就可以发现SD卡设
备，效果与读卡器相同。对于容量较大的设备，需要一定的扫描时间才可以打开。正常运行
后开发板LED1灯不断闪烁。
