config USERLED
bool "LED driver"
default n
depends on ARCH_HAVE_LEDS
---help---
Enable standard user LED upper half driver.

config USERLED_LOWER
bool "Generic Lower Half LED Driver"
default n
---help---
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
2. The board.h header file must provide the definition
BOARD_NLEDS, and
3. The board.h header file must not include any other
header files that are not accessibble 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
userled_lower.c file can still be copied to your your
board src/ directory and modified for your specific board
requirements.
