【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

(硬石YS-F1Pro开发板HAL库例程持续更新\1. 软件设计之基本裸机例程(HAL库版本)\YSF1_HAL-059. USB-SD卡模拟U盘)
/**
******************************************************************************
* 硬石YS-F1Pro开发板例程功能说明
*
* 例程名称: YSF1_HAL-059. USB-SD卡模拟U盘
*
******************************************************************************
* 说明:
* 本例程配套硬石stm32开发板YS-F1Pro使用。

【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。
