|
|
---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
|
|
|
|
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.

depends on RGBLED
|
|
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.

|
|
config RGBLED_LIGHTNESS_CORRECTION
|

bool "Apply Lightness Correction"
|
|
depends on RGBLED
|
|
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.
