Added support to LIS2MDL Magnetometer sensor provided
with following features:
- I2C interface
- Mag data
- Temperature data
- ODR configurable by config or at runtime
- Trigger mode selectable by menuconfig
- IRQ pin configurable (by dts or Kconfig)
- Hard Iron offset setting at runtime
- Include yaml file
Tested on ST MEMS IKS01A2 + NUCLEO STM32F411RE board.
LIS2MDL connected to I2C master interface (SPI 3 wire not
supported yet).
Test run with all ODR {10, 20, 50, 100} Hz in poll and
trigger mode.
GPIO IRQ dts configuration has been tested by adding
to boards/arm/nucleo_f411re/nucleo_f411re.dts file
this patch:
&i2c1 {
status = "ok";
clock-frequency = <I2C_BITRATE_FAST>;
+
+ /* ST Microelectronics LIS2MDL mag sensor */
+ lis2mdl-magn@1e {
+ compatible = "st,lis2mdl-magn";
+ reg = <0x1e>;
+ irq-gpios = <&gpioa 4 0>;
+ label = "LIS2MDL";
+ status = "ok";
+ };
};
and adding boards/arm/nucleo_f411re/dts.fixup with following
content:
ST_STM32_I2C_V1_40005400_ST_LIS2MDL_MAGN_1E_LABEL
ST_STM32_I2C_V1_40005400_ST_LIS2MDL_MAGN_1E_BASE_ADDRESS
ST_STM32_I2C_V1_40005400_ST_LIS2MDL_MAGN_1E_BUS_NAME
ST_STM32_I2C_V1_40005400_ST_LIS2MDL_MAGN_1E_IRQ_GPIOS_CONTROLLER
ST_STM32_I2C_V1_40005400_ST_LIS2MDL_MAGN_1E_IRQ_GPIOS_PIN
