1STM32Cube操作

1-1配置时钟

1-2配置调试端口

1-3配置uart

1-4配置SDIO

选择数据传输引脚个数

需改配置（图中改了两处，选中的和最后一个）

1-5打开DMA

传输方向改为图中的（由内转向外设）在改图中的一次读写的大小

1-6再打开sdio的中断

1-7生成代码（注意）

重点图中其他配置和平常一样但库的选择选v1.8.3（我用1.8.5时有问题生成的代码检测到卡时程序就卡死了。有懂得大佬可以在评论区中讲解一下吗）

2代码编写

2-1修改代码

选择次函数跳到函数调用的地方

2-2注释代码

图中标志的地方注释它

（当初始化时，检测不到sd卡时会进入此函数，此函数是一个无限制的死循环）

上面的函数下方还有一个

注意

有些的版本过低（软件版本）可能会出现（SDIO_BUS_WIDE_1B）是（SDIO_BUS_WIDE_4B）的情况改为（SDIO_BUS_WIDE_1B）即可但如果你是使用宽度为4比特的话不用改

2-3添加代码使其检测SD卡

(添加进main函数的while循环中)

2-4main.c源码
