nPM1300 EK sample
#################
Overview
********
This sample is provided for evaluation of the :ref:`npm1300_ek`.
The sample provides a shell interface to support the features of the
nPM1300 PMIC, including:
- Regulators (BUCK1/2, LDO1/2)
- GPIO
Requirements
************
The shield needs to be wired to a host board supporting the Arduino connector.
Examples and images to follow
Building and Running
********************
The sample is designed so that it can run on any platform. For example, when
building for the nRF52 DK, the following command can be used:
.. zephyr-app-commands::
:zephyr-app: samples/shields/npm1300_ek
:board: nrf52dk_nrf52832
:goals: build
:compact:
Note that this sample automatically sets ``SHIELD`` to ``npm1300_ek``. Once
flashed, you should boot into the shell interface. The ``regulator`` command is
provided to test the PMIC. Below you can find details for each subcommand.
Regulators
==========
The ``regulator`` shell interface provides several subcommand to test
the regulators embedded in the PMIC. Below you can find some command examples.
.. code-block:: bash
# list all the supported voltages by BUCK1
regulator vlist BUCK1
1.000 V
1.100 V
...
.. code-block:: bash
# enable BUCK2
regulator enable BUCK2
# disable BUCK2
regulator disable BUCK2
.. code-block:: bash
# set BUCK2 voltage to exactly 2V
regulator vset BUCK2 2V
# obtain the actual BUCK1 configured voltage
regulator vget BUCK1
1.800 V
# set BUCK1 voltage to a value between 2.35V and 2.45V
regulator set BUCK1 2.35V 2.45V
# obtain the actual BUCK1 configured voltage
regulator get BUCK1
2.400 V
