Hi everyone,

I create a project in STM32CubeIDE. I have a error which show in figure below,

This is my full file code:

} spi_aml_pcs_polarity_t;

#endif

How do I fix this error ?

Thanks.

First, understand why the compiler believes that there are two or more type declarations.

Enable output of preprocessed C code (how? google, ask chatgpt)  and see what these two MAKE_STATUS(...)  lines become. Or find definition of MAKE_STATUS and preprocess "on paper".
