STMicroelectronics STTS22H temperature sensor connected to I2C bus
When setting the sampling-rate property in a .dts or .dtsi file you
may include stts22h.h and use the macros defined there.
Example:
#include <zephyr/dt-bindings/sensor/stts22h.h>
stts22h: stts22h@0 {
...
sampling-rate = <STTS22H_100Hz>;
};
compatible: "st,stts22h"
include: [sensor-device.yaml, i2c-device.yaml]
properties:
int-gpios:
type: phandle-array
description: interrupt 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.
temperature-hi-threshold:
type: int
default: 0
description: |
HIGH temperature threshold above which an alarm is triggered.
Valid range is 0 to 255. It defaults to 0 (alarm off) which is
the configuration at power-up. This threshold must be calculated
from a temperature T in Celsius using the formula
temperature-hi-threshold = 63 + T/0.64 C.
temperature-lo-threshold:
type: int
default: 0
description: |
LOW temperature threshold below which an alarm is triggered.
Valid range is 0 to 255. It defaults to 0 (alarm off) which is
the configuration at power-up. This threshold must be calculated
from a temperature T in Celsius using the formula
temperature-lo-threshold = 63 + T/0.64 C.
sampling-rate:
type: int
default: 0x0
description: |
Specify the default output data rate expressed in samples per second (Hz).
The values are taken in accordance to stts22h_odr_temp_t enumerative in hal/st
module. Default 0x0 (power down) matches the power-up configuration.
- 0x00 # STTS22H_POWER_DOWN
