Desktop Application?

Can i used FreeRTOS in Dev c++ for have a practiced?

I’m not sure I understand your question. Are you asking if you can use this IDE https://sourceforge.net/projects/orwelldevcpp/ ? If so then I’ve never used it but if it is a text editor then assume the answer would be yes. If you are asking if FreeRTOS can be used to create desktop applications then you can run FreeRTOS applications on a desktop using the FreeRTOS Windows port or any other software emulator that is capable of executing on Windows - but you cannot write desktop applications in the traditional way with FreeRTOS.

Many thanks my friend.
