Hello,
I am working on STM32F3xx discovery board with HAL driver on keil 5.
i have included the path for my header file from option target menu, but all header files from that included folder path are not getting added. The .c file related to that header file is being added but not the header file.
can any body help me in solving this issue or is there any alternative for that.
It is where, and the order in which, it searches for things, it is not a directive to include everything. You still need to explicitly #include every file you want to include.
I have included the header file #include "stm32f3xx_hal_usart.h" in my code. when i am using function from the header file in my code. The code is compiling but shows an error while linking as below
compiling tim.c... assembling startup_stm32f303xc.s... compiling usart.c... compiling funciones.c... compiling system_stm32f3xx.c... linking... prueba1\prueba1.axf: Error: L6218E: Undefined symbol HAL_USART_Init (referred from usart.o). Not enough information to list image symbols. Finished: 1 information, 0 warning and 1 error messages. "prueba1\prueba1.axf" - 1 Error(s), 8 Warning(s). Target not created. Build Time Elapsed: 00:00:18
If i remove function HAL_USART_Init from code then it works perfectly.
It seems because of header file #include "stm32f3xx_hal_usart.h" not getting included in include path.
Can you cross check by explicitly adding the path od this header file through Options for target -> C/C++ tab ?
Each include file in the HAL expects a specific #define to enable inclusion.
So in your project's stm32f4xx_hal_conf.h

If in doubt dig into the source, including the libraries, to see what the compiler is being feed.
Thank you Westonsupermare Pier for the solution.
