# # For a description of the syntax of this configuration file, # see the file kconfig-language.txt in the NuttX tools repository. # menu "LED Support" 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. 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 endmenu # LED Support
