how can I access a specific accelerometer if there are more than one?

Question

If there is more than one accelerometer present, how can I obtain a list and then select which one to subscribe to?

Answer 1

Maureen,

Is this for testing purposes or would the shipping product have two accelerometers?

Answer 2

Hi Eric,

This is for testing purposes - I have a USB dongle board with many sensors (accel, gyro, compass, etc) that we use to demo our sensor fusion reference design. I want to make sure my Windows app uses data from the dongle board rather than from the sensors internal to the tablet. The only way I know of to access the sensor is:

_accelerometer = Accelerometer.GetDefault();

Ideally I would like to obtain a list of available sensors and allow the user to select which one to use.

I'm curious though why it makes a difference if this is for testing purposes or shipping product?

Thanks,

Maureen

Maureen,

You will want to disable the built in accelerometer in device manager.
