# # 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 depends on ARCH_HAVE_LEDS ---help--- Enable standard user LED upper half driver. if USERLED 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//src/) 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. endif # USERLED 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. endmenu # LED Support
