      While working with StmCubeIDE, I use the following lines of code to print the float element to the screen with uart. The strings are written to the Termite screen, but the floats are not written to the screen

      HAL_UART_Transmit(&huart3,Data,sprintf(Data,"Pressure: %4.2f Pa \t Temperature: %4.2f C \t Altitude: %4.2f m",pressure,temperature,altitude),HAL_MAX_DELAY);

      4- Click on Setting option
      5-Open MCU GCC Linker option in Tool Settings
