.. zephyr:code-sample:: lp3943
:name: LP3943 RGBW LED
:relevant-api: led_interface
Control up to 16 RGBW LEDs connected to an LP3943 driver chip.
Overview
********
This sample controls 16 LEDs connected to an LP3943 driver, in
a continuous pattern of turning them on one at a time (at a one
second interval) until they're all on, and then turning them off in
reverse order.
Requirements
************
The :ref:`96b_neonkey` board has an LP3943 driver and 16 LEDs on board,
so we'll use this board for our example.
Building and Running
********************
Build the application for the :ref:`96b_neonkey` board, which has an
LP3943 driver included.
.. zephyr-app-commands::
:zephyr-app: samples/drivers/led_lp3943
:board: 96b_neonkey
:goals: build
:compact:
For flashing the application, refer to the Flashing section of the
:ref:`96b_neonkey` board documentation.
When you connect to the board's serial console, you should see the
following output in addition to the LED pattern:
.. code-block:: none
