This is the documentation for the latest (main) development branch of Zephyr. If you are looking for the documentation of previous releases, use the drop-down menu on the left and select the desired version.

st,ism330dhcx (on i2c bus)

Vendor: STMicroelectronics

Description

STMicroelectronics ISM330DHCX 6-axis IMU (Inertial Measurement Unit) sensor
accessed through I2C bus

Properties

Properties not inherited from the base binding file.

Name

Type

Details

supply-gpios

phandle-array

GPIO specifier that controls power to the device.

This property should be provided when the device has a dedicated
switch that controls power to the device.  The supply state is
entirely the responsibility of the device driver.

Contrast with vin-supply.

vin-supply

phandle

Reference to the regulator that controls power to the device.
The referenced devicetree node must have a regulator compatible.

This property should be provided when device power is supplied
by a shared regulator.  The supply state is dependent on the
request status of all devices fed by the regulator.

Contrast with supply-gpios.  If both properties are provided
then the regulator must be requested before the supply GPIOS is
set to an active state, and the supply GPIOS must be set to an
inactive state before releasing the regulator.

drdy-gpios

phandle-array

DRDY gpio pin

This pin defaults to active high when produced by the sensor.
The property value should ensure the flags properly describe
the signal that is presented to the driver.

int-pin

int

Select DRDY pin number (1 or 2).

  Selection
    1  drdy is generated from INT1
    2  drdy is generated from INT2

This number represents which of the two interrupt pins
(INT1 or INT2) the drdy line is attached to. This property is not
mandatory and if not present it defaults to 1 which is the
configuration at power-up.

Default value: 1

Legal values: 1, 2

accel-odr

int

Specify the default accelerometer output data rate expressed in samples per second (Hz).
Default is power-up configuration.

  Selection
    0   Power-Down
    1   12.5Hz
    2   26Hz
    3   52Hz
    4   104Hz
    5   208Hz
    6   416Hz
    7   833Hz
    8   1660Hz
    9   3330Hz
    10  6660Hz

Legal values: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10

accel-range

int

Range in g. Default is power-up configuration.

  Selection
    16  16g (0.488 mg/LSB)
     8   8g (0.244 mg/LSB)
     4   4g (0.122 mg/LSB)
     2   2g (0.061 mg/LSB)

Default value: 2

Legal values: 16, 8, 4, 2

gyro-odr

int

Specify the default gyro output data rate expressed in samples per second (Hz).
Default is power-up configuration.

  Selection
    0   Power-Down
    1   12.5Hz
    2   26Hz
    3   52Hz
    4   104Hz
    5   208Hz
    6   416Hz
    7   833Hz
    8   1660Hz
    9   3330Hz
    10  6660Hz

Legal values: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10

gyro-range

int

Range in dps. Default is power-up configuration.

  Selection
    125    +/- 125dps
    250    +/- 250dps
    500    +/- 500dps
    1000   +/- 1000dps
    2000   +/- 2000dps

Default value: 125

Legal values: 125, 250, 500, 1000, 2000

friendly-name

string

Human readable string describing the sensor. It can be used to
distinguish multiple instances of the same model (e.g., lid accelerometer
vs. base accelerometer in a laptop) to a host operating system.

This property is defined in the Generic Sensor Property Usages of the HID
Usage Tables specification
(https://usb.org/sites/default/files/hut1_3_0.pdf, section 22.5).
