Anas Nashif 3ae52624ff license: cleanup: add SPDX Apache-2.0 license identifier Update the files which contain no license information with the 'Apache-2.0' SPDX license identifier. Many source files in the tree are missing licensing information, which makes it harder for compliance tools to determine the correct license. By default all files without license information are under the default license of Zephyr, which is Apache version 2. Signed-off-by: Anas Nashif <anas.nashif@intel.com>		2019-04-07 08:45:22 -04:00

LP3943: 16-Channel RGB, White-LED Driver
########################################

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

   ***** BOOTING ZEPHYR OS v1.11.99 *****
   [general] [INF] main: Found LED device LP3943
   [general] [INF] main: Displaying the pattern
