LEDs and Buttons ​

LEDs ​

The nRF5340-Audio-DK has 4 user-controllable LEDs:

LED MCU


LED1 P0.31 LED2 P1.01 LED3 P1.02

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);

Pushbuttons ​

BUTTON MCU


BUTTON1 P0.02 BUTTON2 P0.03 BUTTON3 P0.04 BUTTON4 P0.05 BUTTON5 P0.06

Configurations ​

Each configuration is maintained in a sub-directory and can be selected as follow:

tools/configure.sh nrf5340-audio-dk:<subdir>

Where <subdir> is one of the following:

nsh_cpuapp ​

Basic NuttShell configuration for the application core (console enabled in UART0, exposed via J-Link VCOM0, at 115200 bps).
