If the board supports the standard LED interfaces as

defined in include/nuttx/board.h header file, then this
|
|
|
|
|
standard LED lower half driver might be usable.
|
|

|
|
|
|
|
In order for this generic driver to be usable:
|
|
|
|
|
|
|
|
|
|
1. The board implementation must provide the LED
|
|
|
|
|
interfaces as defined in include/nuttx/board.h
|
|
|
|
|
|
|
|
|
|
If your board does not meet these requirements, then the

|
|
|
|
userled_lower.c file can still be copied to your your
|
|
|
|
|
board src/ directory and modified for your specific board
|
|
|
|
|
requirements.
