Not work accelerometer, magnetometer and ambientlight sensors (Lenovo Yoga Tablet 2)

[Kitsune]

On my tablet is lsm303d accel and magn, in kernel no this driver, and this error with magnetometer:

i2c i2c-4: Failed to register i2c client MAGN0001:00 at 0x1d (-16) 
i2c i2c-4: failed to add I2C device MAGN0001:00 from ACPI

i'm found this driver https://github.com/robertbcalhoun/meta-lsm303d/tree/master/recipes-kernel/st-lsm303d/files 

in dmesg: lsm303d driver: init

Accel not work.

Ambientlight sensor is AL3320B, but with AL3340a driver in kernel, light sensor not work. In dmesg no messages for this driver.

I partially fix problem, device registered. Dmesg: https://drive.google.com/file/d/0B0wusAQaS8ewdjVIZ0VCb3VwNEk/view?usp=sharing

Not work magnetometer, but i can view values acelerometer in file /sys/devices/platform/80860F41:04/i2c-4/i2c-ACCL0001:00/accelerometer/gsensor_data , when i'm enable accel in file enable_device

Light sensor values in /sys/devices/virtual/input/input4/lux

But autorotate not work and apps don't show the values from sensors? How do it?

[Chih-Wei Huang]

You need to write a sensor HAL to handle the events.
Read the sensors porting guide from AOSP:
https://source.android.com/devices/sensors/

You may refer to the code in hardware/libsensors
as examples.

Thank you for answer.

I found HAL https://github.com/STMicroelectronics/STMems_Android_Sensor_HAL_Input but they not compile in /out/target/product/<board>/system/vendor/lib/ no folder hw. 

In device.mk I add: PRODUCT_PACKAGES += sensors.android_x86_64

in Android.mk ENABLED_SENSORS := LSM303D

How fix Operation not permitted?

Try to change owner.group to system (1000), say

chown 1000.1000 /sys/class/input/event?/device/device/*/*

[Kitsune]

Thanks for answer it work, but no autorotate. Yet i'm write iio driver for lsm303d, accelerometer, magnetometer work, is values, but autorotate not work, need other sensors?

 How i can get others sensors? Composite sensors type? Gravity, rotation vector, orientation and etc.? In STM repo no needed libraries...

Don't know what you meant.
You said it works, but no autoroate?
Then how do you know it works?

The accelerometer is enough for autoroate.

You can use some sensors test tools
to check if they produce correct value
that the framework expects.

In cpu-z is this accelerometer values (screenshot): https://drive.google.com/file/d/1iYRjdE-Y0cq4LauXA7CwobwIpjZmYJz5/view?usp=sharing 

In windows the same accelerometer values: https://drive.google.com/open?id=1mHYYldNjfCCBpLrAATEkRPwD36BNORXV

I'm watch in smartphone this values it is "rotation vector" values

This is the sensors hal name.
We don't have such a hal.
Is it the hal name you added yourself?

[Kitsune]

I'm add some changed iio HAL: https://drive.google.com/open?id=15h-XvybErgnUo5-7Kd-7NhrDcOfF4_Mi
In /lib/hw/sensors.lyt2.so is. I thinking it my problem in HAL, but I trying change lyt2 in not right s103t. But In cpu-z i see the same picture: https://drive.google.com/file/d/1D099auYWJsmwu6gw56_0u3gMq03bZlGe/view?usp=sharing
The same picture i'm see without selected hal. Device name is right. I'm think not select needed HAL...

Oh. It looks like the same hal I wrote.
Then why not just use sensors.iio?

BTW, in the latest 7.1 I've replaced my sensors.iio
with intel's which seems to provide better functions.
You should sync and build the latest nougat-x86 branch
to test it.

[Kitsune]

Yes, It your HAL, but me need some changes:

data[i].acceleration.x = scale * (m[0] * v[0] + m[1] * v[1] + m[2] * v[2]) * (-9.81);
data[i].acceleration.y = scale * (m[3] * v[0] + m[4] * v[1] + m[5] * v[2]) * (-9.81);
data[i].acceleration.z = scale * (m[6] * v[0] + m[7] * v[1] + m[8] * v[2]) * (-9.81);

data[i].magnetic.x = scale_x * (m[0] * v[0] + m[1] * v[1] + m[2] * v[2]) * 100;
data[i].magnetic.y = scale_y * (m[3] * v[0] + m[4] * v[1] + m[5] * v[2]) * 100;
data[i].magnetic.z = scale_z * (m[6] * v[0] + m[7] * v[1] + m[8] * v[2]) * 100;

and seems this:
// conversion of acceleration data to SI units (m/s^2)
#define RANGE_A                     (16*GRAVITY_EARTH)
#define RESOLUTION_A                (0.0f)

// conversion of magnetic data to uT units
#define RANGE_M                     (1200.0f)
#define RESOLUTION_M                (0.0f)

It need for correctly values showing.

You should sync and build the latest nougat-x86 branch
to test it.

 

I'm compile latest nougat branch, seems intel HAL shows this: https://drive.google.com/file/d/1D099auYWJsmwu6gw56_0u3gMq03bZlGe/view?usp=sharing It shows default. Even if not any changes in init.sh

I'm don't know how use your iio HAL which correctly work with my sensors. In hardware/libsensors/Android.mk need delete  ifeq ($(USE_MY_SENSORS_IIO),true) ? But how set to default this HAL?

You don't need to change the code.
Just set the property hal.sensors.iio.accel.matrix.

Similarly, set it to hal.sensors.iio.magn.matrix

As I said, it's replaced by new android-iio-sensors-hal
(code in hardware/intel/libsensors/ )
If you have correct iio device nodes
(ls /sys/bus/iio/devices/iio:device* is not null)
it will be used automatically.

You may need to set ro.iio.accel.?.opt_scale property
to calibrate it (? = x, y, z)
