In order for this generic driver to be usable:

1. The board implementation must provide the button

interfaces as defined in include/nuttx/board.h
|
|
2. The board implementation must support interrupts for each

button.

3. The board.h header file must provide the definition

NUM_BUTTONS, and

4. The board.h header file must not include any other
|
|
header files that are not accessible in this context
|
|
(such as those in arch/<arch>/src/<chip>) UNLESS those
|
|
inclusions are conditioned on __KERNEL__. button_lower.c
|

will undefine __KERNEL__ before included board.h.

If your board does not meet these requirements, then the

requirements.
