| The ASM330 is a highly integrated, low power inertial measurement unit (IMU) |
| that provides precise acceleration and angular rate (gyroscopic) measurement. |
| |
| To enable driver probing, add the asm330lhh node to the platform device tree as described below. |
| |
| Required properties: |
| |
| - compatible: "st,asm330lhh" |
| - reg: the I2C address or SPI chip select the device will respond to |
| - interrupt-parent: phandle to the parent interrupt controller as documented in [interrupts][4] |
| - interrupts: interrupt mapping for IRQ as documented in [interrupts][4] |
| |
| Recommended properties for SPI bus usage: |
| - spi-max-frequency: maximum SPI bus frequency as documented in [SPI][3] |
| |
| Optional properties: |
| - st,drdy-int-pin: MEMS sensor interrupt line to use (default 1) |
| |
| I2C example (based on Raspberry PI 3): |
| |
| &i2c0 { |
| status = "ok"; |
| #address-cells = <0x1>; |
| #size-cells = <0x0>; |
| asm330lhh@6b { |
| compatible = "st,asm330lhh"; |
| reg = <0x6b>; |
| interrupt-parent = <&gpio>; |
| interrupts = <26 IRQ_TYPE_EDGE_RISING>; |
| }; |
| |
| SPI example (based on Raspberry PI 3): |
| |
| &spi0 { |
| status = "ok"; |
| #address-cells = <0x1>; |
| #size-cells = <0x0>; |
| asm330lhh@0 { |
| spi-max-frequency = <500000>; |
| compatible = "st,asm330lhh"; |
| reg = <0>; |
| interrupt-parent = <&gpio>; |
| interrupts = <26 IRQ_TYPE_EDGE_RISING>; |
| }; |
