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.
|
||
|
|

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`_.

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
