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).
