How to use the st_imu68 IIO driver with a hrtimer? about stmems_linux_iio_drivers

[mariotesi]

Hi deblauwetom,

Yes I confirm the raw value can be read using the

/sys/bus/iio/devices/iio:devicex/in_xxx_x_raw
/sys/bus/iio/devices/iio:devicex/in_xxx_y_raw
/sys/bus/iio/devices/iio:devicex/in_xxx_z_raw

but is very slow because is only for spare access

To read data in a standard way (using FIFO and iio channels) there is the generic_buffer iio utility in linux kernel documentation, otherwise you can use the Linux/Android HAL in this repository:
https://github.com/STMicroelectronics/STMems_Android_Sensor_HAL_IIO

Generic Buffer utility need the scan_elements directory but in st_imu68 there should be this entry path (please see in CONFIG_IIO_BUFFER is enabled in your .config)
