Hi, I need to force compiler option to signed char type as I porting a big project to stm32. Sorry but I not see how to do. :) Thanks

[LPode.1]

option to force UNSIGNED CHAR

[KnarfB]

depends on the compiler you are using

[LPode.1]

Thanks for your reply!

I using STM32CubeIDE for stm32F446, in the properties settings I see toolchain set to GNU tools for STM32

-funsigned-char

[LPode.1]

:) BIG THANKS

Where should be added?

I trying in Properties->C/C++ Build->Settings->Tool Settings->MCU GCC Compiter->Miscellaneous->Other flags

but not works

[KnarfB]

can you give a source code line example what didn't work and what is the compiler message

[KnarfB]

That's another warning. char remains a separate type and so that warning remains regardless of signed/unsigned.

:thumbs_up: Thanks
