Warning: #223-D: function "Assert_param" declared implicitly

Hardware platform: stm32f205

1.1-point tracking, found that most of the header files are included in the stm32f10x_conf.h, and this file appears in Stm32f10x.h, which has such a paragraph: #ifdef use_stdperiph_driver #include " Stm32f10x_conf.h "#endif

The original is this use_stdperiph_driver is not defined, Stm32f10x_conf.h header file can not be compiled into the project, resulting in an error.

Find solutions from online search,

MDK Right-click on the project, select options, select the C + + option, in the defined box to fill in Use_stdperiph_driver.

Add "Use_stdperiph_driver" to that define.
