config USERLED
bool "LED driver"
default n
---help---
Enable standard user LED upper half driver.
if USERLED
config USERLED_LOWER
bool "Generic Lower Half LED Driver"
default n
depends on ARCH_HAVE_LEDS
---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.
config USERLED_LOWER_READSTATE
bool "LED Driver Read Actual Pin State"
default n
depends on USERLED_LOWER
---help---
Extends the standard LED interface as defined in the
include/nuttx/board.h header file with a function that
checks the actual state of the pin controlling the LED,
which can be used to find malfunctioning LEDs.
endif # USERLED
config LEDS_APA102
bool "APA102 LED Strip"
default n
select SPI
---help---
Enable support for the APA102 LED Strip driver.
config LEDS_MAX7219
bool "MAX7219 Numeric Display"
default n
select SPI
---help---
Enable support for the MAX7219 to control 7-segment displays.
config RGBLED
bool "RGB LED Driver Support"
default n
---help---
This selection enables building of the "upper-half" RGB LED driver.
See include/nuttx/rgbled.h for further PWM driver information.
config RGBLED_INVERT
bool "Invert RGB LED Output"
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.
config PCA9635PW
bool "PCA9635PW I2C LED Driver"
default n
select I2C
---help---
Enable support for the NXP PCA9635PW LED driver which can be
utilized to drive up to 16 LED's.
config NCP5623C
bool "NCP5623C I2C LED Driver"
default n
select I2C
---help---
Enable support for the onsemi NCP5623C LED driver which can be
utilized to drive up to 3 LED's.
config WS2812
bool "WS2812 LED Driver"
default n
select SPI
---help---
Enable support for the Worldsemi WS2812 LED driver which commonly
found in LED strips.
NOTE: This device is a one wire device and has no CS or RESET
line it must have exclusive use of the bus!
config WS2812_FREQUENCY
int "WS2812 LED Driver SPI Frequency"
default 8000000
depends on WS2812
