Although I appreciate your work on the API, I dont see any use (except for automatic screen rotation) in using sensors in serious applications.

hello. i think this is a great work, i can actually interact with the accelerometer and the light sensor. but if i would like to interact with camera, microphone, GPS and so on how can i do? i saw for example that the code to get light from the light sensor is 0x220004, used in NativeMethods.DeviceIoControl. i'd like to know if there are other similar hex for other sensors.
thank you very much

There were some questions previously raised about the Accelerometer polling frequency limited at 25hz (both here and at scottandmichelle.net), but without any solution. Has anyone come across ways to increase this number?

Ricardo Sampaio: Have you investigated modifying the accel capture time in the registry? I'd appreciate hearing what you have learned, or even advice on how I can investigate this myself.

Hi Koush,

While using it with Samsung's omnia, getvector throws error "Unable to perform operation." when device is made lock and unlock again. It works fine until device is made lock and unlock.

Issue is not found with HTC code.

Any clues?

Thanks,
Krupal

Hey Koush,

Thanks a lot for this wonderful managed code for sensor. Due to this code I am able to develop G-Trigger, shake and launch application :)

Thanks Again :)

Hello, first of all: Many thanks for for your work developing such a nice piece of software.
But, do you know whether it is possibble to access Diamonds GPS receiver via C#.
And is it possible to access phone functions like sending an SMS via C# as well?

Hi Kaushik,

Do you have a version of your sample code that does not use .net?

My project is in unmanaged, standard win32, and want to access the capacitive touch area at the bottom of my htc.

Thanks

How can we change this application to carpenter's bubble level, inch ruler, and centimeter ruler? If its possible can you give us a sample code?

Regards.

Hi kaushik,
nice work dude.
But tell me one thing, when the Gvector changes if we get some event or we have to keep checking every time to know GVector is changed or not?
Like Orientation change event there must be some event to notify tha the GVector of device is changed.

Hi Kaushik!First of all...I have to say that your ...

2008-11-08T11:00:00.000-08:00

Hi Kaushik!

First of all...I have to say that your site and work is awesome. I am a big fan of your work.

I was trying your IGsensor interface and copied the code from your sensortest (teeterish) app, but I noticed that the orientationchanged event never fires.
IGSensor myGensor (class variable)

Form_Load()
------------ myGSensor = GSensorFactory.CreateGSensor();
myGSensor.OrientationChanged += new OrientationChangedHandler(mySensor_OrientationChanged);

Event Handler
------
void mySensor_OrientationChanged(IGSensor sender)

I noticed in Klaxon and Gsensor test app that you are actually using a timer to inspect the orientation...and not using the event at all.

But I don't care about the rotate, I wish to know the displacement.
I can't separate gravity from the vector. Can it return the vector without gravity?

2008-10-28T00:01:00.000-07:00

To read the light sensor, use this :
const LPCWSTR pLightSensorName = L"BKL1:";
#define IOCTL_LIGHT_GET 0x220004
Values range from 0 (dark) to 15 (max light).
There are other signals I have not investigated these.

2008-10-27T23:44:00.000-07:00

Hello,
I have found other interesting signals in the Omnia acc sensor driver to get data.

#define IOCTL_ACS_READ1 0x3f3 // reads an integer x ?
#define IOCTL_ACS_READ2 0x3f4 // reads an integer y ?
#define IOCTL_ACS_READ3 0x3f5 // reads an integer z ?
#define IOCTL_ACS_READ4 0x3f6 // reads a vector (x/y/z ?)

I have not been able to fully understand the meaning of the values, and hope you will be able to do something with it.

The breakpoint will not be hit.
Please help, thanks.

2008-10-05T13:06:00.000-07:00

Yes it has one, it's left of the front camera. In fact you have the option in the backlight settings to set it to automatic andit shows you the actual brightness of the environment. Just checked. :)

2008-10-05T07:49:00.000-07:00

Hi Koush, I highly appreciate your work and I was thinking about giving you an idea for expanding its capabilities regarding the Samsung Omnia.
I was thinking if it could be possible to modify the Light sensor API to support the light sensor in the Omnia too.
That could be a great step forward for implementations.
Keep it up the good work!

You can change the acc capture time in the registry, but i dint test to see if affects the readings.

2008-09-15T05:32:00.000-07:00

Hi Koushik, thanks a lot for this!

One question: have you ever noticed than you cannot get values from the G-sensor more than 25 times per second? If you try with a higher frequency, the values are not changing (??)

I've seen that you have chosen a 40ms timer interval in your examples, so i wonder if this value was chosen randomly or not :)
