| Sensirion SHTCx humidity and temperature sensor |
| |
| Additionally use "sensirion,shtc1" or "sensirion,shtc3" compatibles |
| such that a generic driver can consider chip specific behaviour. |
| |
| Example device tree node describing a Sensirion SHTC3 Sensor on the i2c0 bus: |
| |
| &i2c0 { |
| status = "okay"; |
| clock-frequency = <I2C_BITRATE_FAST>; |
| shtc3@70 { |
| compatible = "sensirion,shtc3", "sensirion,shtcx"; |
| reg = <0x70>; |
| measure-mode = "normal"; |
| clock-stretching; |
| }; |
| }; |
| |
| compatible: "sensirion,shtcx" |
| |
| include: [sensor-device.yaml, i2c-device.yaml] |
| |
| properties: |
| measure-mode: |
| type: string |
| required: true |
| description: | |
| Specifies which measurement mode is used. |
| SHTC1 sensor only supports the normal measuremnt mode. |
| enum: |
| - "normal" |
| - "low-power" |
| |
| clock-stretching: |
| type: boolean |
| description: | |
| Specifies that the driver should clock stretching i2c communication to |
| read the sensor values. |
