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

config RGBLED_INVERT

bool "Invert RGB LED Output"

|
|
default n
|
|
---help---
|
|
If the board has a common anode RGB LED (a LOW output turns ON
|
|
each LED), this selection inverts the outputs so that the
|
|
colors are displayed correctly.

default n

---help---
|

This selection enables an approximate CIE 1931 lightness
|
|
correction which helps the RGB LED visually fade and blend
|
|
in a more linear, smooth, and visually appealing fashion.
