As a common component of examples, this component can provide unified pin macro definitions and hardware-independent initialization operations to applications. Applications developed based on this component are compatible with different development boards at the same time.

• The Boards component contains the following:

  • board_common.h, contains the function declaration of the common API;
  • board_common.c, contains the function implementation of the common API (weak function);
  • Kconfig.projbuild, contains common configuration items;

• The subfolders named after the development board name includes the following:

  • iot_board.h provides the gpio definition of the development board, and the board's unique custom API function declaration
  • board.c provides user implementation of common API (Covering default weak function), custom API function implementation
  • kconfig.in provides custom configuration items unique to the development board.
