| The BMP581 is a Barometric pressure sensor. See more info at: |
| https://www.bosch-sensortec.com/products/environmental-sensors/pressure-sensors/bmp581/ |
| |
| When setting the sensor DTS properties, make sure to include |
| bmp581.h and use the macros defined there. |
| |
| Example: |
| #include <zephyr/dt-bindings/sensor/bmp581.h> |
| |
| bmp581@46 { |
| ... |
| odr = <BMP581_DT_ODR_50_HZ>; |
| press-osr = <BMP581_DT_OVERSAMPLING_8X>; |
| temp-osr = <BMP581_DT_OVERSAMPLING_4X>; |
| press-iir = <BMP581_DT_IIR_FILTER_COEFF_7>; |
| temp-iir = <BMP581_DT_IIR_FILTER_COEFF_3>; |
| power-mode = <BMP581_DT_MODE_NORMAL>; |
| }; |
