   :name: LP5569 9-channel LED controller
   :relevant-api: led_interface

   Control 9 LEDs connected to an LP5569 driver chip.

Overview
********

This sample controls 9 LEDs connected to an LP5569 driver. The sample turns
all LEDs on one by one with a 1 second delay between each. Then it fades all
LEDs until they are off again. Afterwards, it turns them all on at once, waits
a second, and turns them all back off.
This pattern then repeats indefinitely.

Building and Running
********************

Build the application for the :zephyr:board:`nrf52840dk` board, and connect
a LP5569 LED controller on the bus I2C0 at the address 0x32.

For flashing the application, refer to the Flashing section of the
:zephyr:board:`nrf52840dk` board documentation.
