st,stm32-temp

Vendor: STMicroelectronics

Note

An implementation of a driver matching this compatible is available in drivers/sensor/st/stm32_temp/stm32_temp.c.

Description

STM32 family TEMP node

Properties

Properties not inherited from the base binding file.

Name

Type

Details

v25

int

Voltage of temperature sensor at 25°C (in mV), found in MCU datasheet
chapters "Electrical characteristics" or "Operating conditions"

This property is required.

avgslope

string

Average slope of T-V chart (in mV/°C), found in MCU datasheet
chapters "Electrical characteristics" or "Operating conditions"

This property is required.

ntc

boolean

Negative Temperature Coefficient

Set when the sensor's value is inversely proportional to temperature
(i.e., the sensor's value decreases as the temperature increases).

This is visible in the formula used for temperature calculation, which has the
form "Calibration_Value - ADC_Value" rather than "ADC_Value - Calibration_Value".

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).
