I set all the pins in CubeMx,

added a class to a .h file

renamed main.c to main.cpp

included the .h

and 'class' is undefined.

is there a switch in Cube for this ? 

using an '091

#class-undefined #uv5 #keil

Needs to be a .CPP file that does the including, or you need to add the --cpp to enable compiler support. ie compile .C as C++

One has to watch for C++ name mangling, functions you wish to export to the vector table, for example, need extern 'C' prefix so they bind properly in the linker, rather than the WEAK ones. The SysTick Handler being one to watch in CubeMX/HAL

ie

extern 'C' void USART1_IRQHandler(void)

{

 ...

}
