Hi,

I wrote an application as below which prints formatted values. However, when I print the Adc.IntSensTmp, I dont see the value as expected. Instead, I see the output below. Could you pls help me resolve ?

Thanks.

 

Here is the output I get.

Need to enable the floating point printf() libraries, or use dtoa()

Thank you very much. 

I did it by enabling a flag as below.

Project -- > properties --> C/C++ Build --> settings --> MCU GCC Linker --> Misc --> Other flags

add -u_printf_float

There are dedicated checkboxes for this in STM32CubeIDE.

The compiler also issues a warning about this if you have "%f" in a printf statement without those checkboxes enabled.
