使用步骤：
1. 插入SD卡，MCU侧SD卡引脚如下：
  PD2:  CMD
  PC8:  D0
  PC9:  D1
  PC10: D2
  PC11: D3
  PC12: SCK
2. 编译并下载程序；
3. 按复位按键，运行程序，程序对SD执行擦除、写、读操作；
4. 观察现象，如果写入和读取数据一致LED常亮，否则LED处于熄灭状态。

Example execution steps:
1. Insert SD card, MCU side SD card pins are as follows: 
  PD2:  CMD
  PC8:  D0
  PC9:  D1
  PC10: D2
  PC11: D3
  PC12: SCK
2.Compile and download programs; 
3. Press the reset button to run the program, which erases, writes and reads SD. 
4.  Observe the phenomenon, if the writing and reading data are consistent, the
