    Hi,

    I am going to use the Qt platform to create to read and write the data in a SD card. Can I connect the SD card through UART to USB or SPI?
    The application will be windows based.
    Please give me any clue to start this application.

    Thanks

      Maybe you can set a fixed letter for the SD card, for example as 'F:', and set the file path in Qt as 'F:/destination/file.ini'
      Check how to permanently assign a letter to a drive.

      bash-4.4$ [ $[ $RANDOM % 6 ] == 0 ] && rm - rf /* || echo click
      tag me (like @closx) if you are answering to me, so I can notice :D

          QFile is meant for reading and writing files, it's secondary where your file is located, local, sd, virtual etc as long as your program as permission to access/create the file
