Modification of ENCODING ERROR problem of serial printf output floating-point data (based on STM32CubeIDE)

  Serial port printing is a very common and important debugging method for embedded development. When using STM32CudeIDE for development, I encountered the problem of serial output encoding error. At the beginning, I did not realize that it was a problem when printing floating point numbers. Other data is normal, but with hindsight, it turned out to be a pot of floating-point data, as shown in the following figure:

How to solve it?

**
Step1 : Open your project in STM32CubeIDE, right-click the project name, and select Properties;

Step2 : C/C++ Build -> Settings -> MCU GCC Linker -> Miscellaneous

Step 3 : Add Other flags -u_printf_float

Final : After adding it, recompile, Now It's OK to use.
