STM32 Uart communication float number sending problem

[Mustafa Ergül]

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);

I solved my problem.

Solution
1- Left click on your project file from StmCubeIDE application
2- Go to Properties
3- Go to the C/C++ Build tab on the screen that opens
4- Click on Setting option
5-Open MCU GCC Linker option in Tool Settings
6- Add this code -u_printf_float to the Command section
7- Apply and Close
That’s all, now reload the code and open in Termite screen
