[AC Question]

The Accelerometer Sensor is set to a Range of 2 - 4 g on most devices.
There is no option to turn it up to 8 or 16 G, which my sensor and most others are capable of.
I found some Information but cant get any further how to achieve this.

I have the LIS3DSH Sensor in my Xiaomi Device.

There is a manual which states that in the configuration .hal file you can set
/* ACCELEROMETER SENSOR \*/
#define SENSOR_ACC_LABEL “LSM303DLHC 3-axis Accelerometer“
#define SENSOR_ACC_INCLUDE_FILE_NAME “lsm303dlhc.h“
#define SENSOR_DATANAME_ACCELEROMETER LSM303DLHC_ACC_DEV_NAME
#define ACCEL_DELAY_FILE_NAME “pollrate_ms“
#define ACCEL_ENABLE_FILE_NAME “enable_device”
#define ACCEL_RANGE_FILE_NAME “range”
#define ACCEL_MAX_RANGE 16*GRAVITY_EARTH
#define ACCEL_MAX_ODR 400
#define ACCEL_POWER_CONSUMPTION 0.033f
#define ACCEL_DEFAULT_FULLSCALE 4

But i have no idea how to do this.

I can not Link to the manual since i dont have 10 posts, but you can google for:

AN4156
Application note

would be glad about any information.

If you look at page 10 in http://www.st.com/st-web-ui/static/a...DM00063297.pdf you'll see how. You change the values in the file, then recompile Android. (It's not user-changeable, it's done at the development level.)

Ah ok Thank you.

Hi Rubkat, thank you for the information.
But how does this work?
I cant find where to download the source files.
Or is there already a version on my phone.
And do i compile only the sensor modules or do i recompile the whole android system.
I am really not a pro in the os knowledge.
im glad for any information.
Cheers,
Tolga
