STM32 CubeMX USB_MSC(存储设备U盘）
- STM32 CubeMX
-
- 前言
- 《使用内部Flash》——U盘
- 一、STM32 CubeMX 设置
-
- USB时钟设置
- USB使能
- UBS功能选择
- FATFS功能
- 二、代码部分
-
- 修改代码"usbd_storage_if.c"
- 修改代码"user_diskio.c"
- main函数初始化
- 插上USB实验效果
- 《SPI_SD卡》——U盘
前言
STM32 CubeMX 配置USB将STM32设置可以作为存储设备或者IAP升级功能
《使用内部Flash》——U盘
一、STM32 CubeMX 设置
USB时钟设置
USB使能
UBS功能选择
要注意：stm32f103c8t6内部Flash的1页为1024（1kb）
FATFS功能
二、代码部分
需要修改两个部分：usbd_storage_if.c文件和user_diskio.c文件
修改代码"usbd_storage_if.c"
