zsensor
--- Zephyr sensor bindings¶
The zsensor
module contains a class for using sensors with Zephyr.
class Sensor --- sensor control for the Zephyr port¶
Use this class to access data from sensors on your board. See Zephyr documentation for sensor usage here: Sensors.
Sensors are defined in the Zephyr devicetree for each board. The quantities that a given sensor can measure are called a sensor channels. Sensors can have multiple channels to represent different axes of one property or different properties a sensor can measure. See Channels below for defined sensor channels.
コンストラクタ¶
-
class
zsensor.
Sensor
(device_name)¶ Device names are defined in the devicetree for your board. For example, the device name for the accelerometer in the FRDM-k64f board is "FXOS8700".
メソッド¶
-
Sensor.
measure
()¶ Obtains a measurement sample from the sensor device using Zephyr sensor_sample_fetch and stores it in an internal driver buffer as a useful value, a pair of (integer part of value, fractional part of value in 1-millionths). Returns none if successful or OSError value if failure.
-
Sensor.
get_float
(sensor_channel)¶ Returns the value of the sensor measurement sample as a float.
-
Sensor.
get_micros
(sensor_channel)¶ Returns the value of the sensor measurement sample in millionths. (Ex. value of
(1, 500000)
returns as1500000
)
-
Sensor.
get_millis
(sensor_channel)¶ Returns the value of sensor measurement sample in thousandths. (Ex. value of
(1, 500000)
returns as1500
)
-
Sensor.
get_int
(sensor_channel)¶ Returns only the integer value of the measurement sample. (Ex. value of
(1, 500000)
returns as1
)
