| PNI RM3100 3-axis Magnetometer. |
| |
| The RM3100 can use either I2C or SPI as a communication bus. |
| When using SPI, the device only supports SPI mode 0 or 3. |
| When setting the odr property in a .dts or .dtsi file you may include rm3100.h |
| and use the macros defined there. |
| |
| Example: |
| #include <zephyr/dt-bindings/sensor/rm3100.h> |
| |
| &spi0 { |
| cs-gpios = <&arduino_header 10 GPIO_ACTIVE_LOW>; |
| rm3100@0 { |
| compatible = "pni,rm3100"; |
| reg = <0x0>; |
| spi-max-frequency = <8000000>; |
| |
| // Enable SPI mode 3. Remove to use mode 0. |
| spi-cpol; |
| spi-pha; |
| |
| odr = <RM3100_DT_ODR_600>; |
| }; |
| }; |
| |
| compatible: "pni,rm3100" |
| |
| include: ["spi-device.yaml", "pni,rm3100-common.yaml"] |
