called object is not a function or function pointer in stm32f103xb.h

[Oskar2211]

Hi, 

when i try to build my current project i get: called object is not a function or function pointer in the stm32f103xb.h for whatever peripheral i use. For example 

 

stm32f103xb.h:657:29: error: called object is not a function or function pointer

657 | #define I2C2 ((I2C_TypeDef *)I2C2_BASE)

 

even though it appears to be properly defined in stm32f103xb.h.

any ideas why this happens?

 

thanks in advance

One or more of the above identifiers are probably defined elsewhere in your code with a different meaning. Try to start with a minimal project including stm32f103xb.h only. You may also use your IDE search functions or grep or such to find all occurences of those identifiers in your project

Check stm32f1xx_hal_conf.h is pulling in I2C modules via the defines.
