.. _max17262: MAX17262 Fuel Gauge Sensor ################################### Overview ******** This sample application periodically reads voltage, current and temperature data from the MAX17262 device that implements SENSOR_CHAN_GAUGE_VOLTAGE, SENSOR_CHAN_GAUGE_AVG_CURRENT, and SENSOR_CHAN_GAUGE_TEMP. Requirements ************ The MAX17262 is an ultra-low power fuel-gauge IC which implements the Maxim ModelGauge m5 algorithm. The IC monitors a single-cell battery pack and supports internal current sensing for up to 3.1A pulse current. The IC provides best performance for batteries with 100mAhr to 6Ahr capacity. This sample requires a board which provides a configuration for Arduino connectors and defines node aliases for the I2C interface. For more info about the node structure see :zephyr_file:`samples/sensor/max17262/app.overlay` Building and Running ******************** This sample application uses an MAX17262 sensor connected to a board via I2C. Connect the sensor pins according to the connection diagram given in the `max17262 datasheet`_. .. zephyr-app-commands:: :zephyr-app: samples/sensor/max17262 :board: nrf52840dk_nrf52840 :goals: build flash :compact: Sample Output ============= To check output of this sample , any serial console program can be used. This example uses ``picocom`` on the serial port ``/dev/ttyUSB0``: .. code-block:: console $ sudo picocom -D /dev/ttyUSB0 .. code-block:: console V: 3.626406 V; I: -3.437500 mA; T: 28.011718 °C V: 3.626406 V; I: -3.437500 mA; T: 28.011718 °C V: 3.626406 V; I: -3.437500 mA; T: 28.011718 °C References *********** .. _max17262 datasheet: https://datasheets.maximintegrated.com/en/ds/MAX17262.pdf
