How to know which board is being compiled to be used with an #ifdef

[Pedro]

Hi!

I need to include a specific .h for each board. How can I know, in compiling time, which board is being compiled?

Something like:

#ifdef BOARD_A
#include "board-a.h"
#endif

Thanks!

Pedro.

Hi,

In nRF Connect SDK you can use the CONFIG_BOARD_<BOARD_NAME> config, which comes from the selected build target. For example, for nRF52 DK you can use:

#ifdef CONFIG_BOARD_NRF52DK_NRF52832
#include "board-nrf52dk.h"
#endif

This configuration is defined in the Kconfig.board file for each board, also for custom boards, for example: zephyr/boards/arm/nrf52dk_nrf52832/Kconfig.board.

Best regards,
Marte
