Wish Support for the SDFat library is recommended

[santook]

The official SD is easy to use, but not powerful enough. SDFat library not only includes SD library functions, but also supports disk formatting, etc., including multiple SPI of STM32. It is a very good and fully functional library.

The SdFat 2.0.2 library must be downloaded from the Arduino IDE
A macro definition should be made in the Region Project Attributes of the Main
#DefineExtra:#include "SdFat.h"
#DefineExtra:#include "sdios.h"

#Region Project Attributes
    #AutoFlushLogs: True
    #CheckArrayBounds: True
    #StackBufferSize: 300
