nPM1300 EK

Overview

This sample is provided for evaluation of the 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:

west build -b nrf52dk/nrf52832 samples/shields/npm1300_ek

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.

# list all the supported voltages by BUCK1
regulator vlist BUCK1
1.000 V
1.100 V
...

# enable BUCK2
regulator enable BUCK2
# disable BUCK2
regulator disable BUCK2

# 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
