A low output illuminates the LED.

CONFIG_ARCH_LEDS

If CONFIG_ARCH_LEDS is not defined, then the LEDs are completely under control of the application. The following interfaces are then available for application control of the LEDs:

uint32_t board_userled_initialize(void);
void board_userled(int led, bool ledon);
void board_userled_all(uint32_t ledset);
