PhidgetSpatial 3/3/3 Basic

ID: 1042_0

This spatial board has a 3-axis accelerometer, gyroscope and compass and connects to your computer via USB.

Replaced by 1042_0B

Replaced by the 1042_0B - PhidgetSpatial 3/3/3 Basic. It is the same device, but it comes pre-assembled into a plastic shell enclosure and you can choose which length of USB cable to include.

The PhidgetSpatial 3/3/3 combines the functionality of a 3-axis compass, a 3-axis gyroscope, and a 3-axis accelerometer all in one convenient package. It is an inexpensive alternative to the 1044 - PhidgetSpatial Precision 3/3/3, and is ideal for applications where it's more important to know the general motion of an object rather than the precise amounts.

The 1042 could be used to:

  • Track whether an object is moving, and in which direction
  • Detect the presence of nearby movement or vibration
  • Track the orientation of a stationary object relative to the earth's gravitational pull and the direction relative to magnetic north

Double-click on the Spatial object in order to run the example:

1042 Spatial Example.jpg


The Spatial example demonstrates that you can receive data from the accelerometer, gyroscope, and magnetometer all at once by using the Spatial object rather than the other three objects individually.

Finding The Addressing Information

Before you can access the device in your own code, and from our examples, you'll need to take note of the addressing parameters for your Phidget. These will indicate how the Phidget is physically connected to your application. For simplicity, these parameters can be found by clicking the button at the top of the Control Panel example for that Phidget.

The locate Phidget button is found in the device information box

In the Addressing Information window, the section above the line displays information you will need to connect to your Phidget from any application. In particular, note the Channel Class field as this will be the API you will need to use with your Phidget, and the type of example you should use to get started with it. The section below the line provides information about the network the Phidget is connected on if it is attached remotely. Keep track of these parameters moving forward, as you will need them once you start running our examples or your own code.

All the information you need to address your Phidget

Using Your Own Program

You are now ready to start writing your own code for the device. The best way to do that is to start from our Code Samples.

Select your programming language of choice from the drop-down list to get an example for your device. You can use the options provided to further customize the example to best suit your needs.

Code Sample Choose Language.png


Once you have your example, you will need to follow the instructions on the page for your programming language to get it running. To find these instructions, select your programming language from the Programming Languages page.

Technical Details

3-Axis Accelerometer

The 1042 has a 3-Axis accelerometer that can measure ±8 g (±78 m/s2) per axis. It will measure both dynamic acceleration (change in velocity) and static acceleration (gravity vector).

Orientation

1041 0 Axis Diagram.jpg

When working with an accelerometer it is important to know which is the positive and negative direction on each of the axes. This can be determined by orienting the accelerometer along each axis and checking the output. The above image shows what the axis readings should be for each orientation of the 1042.


For more information on how to use the accelerometer, check the Accelerometer Guide.

3-Axis Gyroscope

For more information on the gyroscope, see the Gyroscope Guide.

3-Axis Magnetometer (Compass)

The magnetometer reports the sum of all magnetic fields acting on the 1042. The Earth's magnetic field is only one source that affects this measurement. In order to get accurate bearing data from the magnetometer ( i.e. to find magnetic north as a compass) any interfering magnetic effects need to be calibrated out. For more information about calibration, see the section below, or the Compass Guide.

Any magnetic field that is stationary with respect to the 1042, and less than ± 3 Gauss, can be calibrated out of the magnetic field measurement. This includes both hard and soft iron effects caused by nearby ferrous and magnetic materials. Interfering magnetic fields that vary in strength and orientation with respect to the 1042 can not be easily calibrated out.

Magnetic field data will become unavailable during every other sample as the compass performs internal calibrations. When this happens, the magneticField array in the SpatialData structure will either have a length of zero, or each element will equal PUNK_DBL, depending on the API being used. This needs to be handled explicitly in the event handling code to avoid erroneous program behavior. The maximum sampling rate of the compass is 125 Hz.


Calibrating the Magnetometer

Magnetometer Calibration

Magnetometer Calibration Guide

In order for your magnetometer to provide accurate heading information, it must be calibrated.

Follow this guide to complete the calibration process.

1. Open the Magnetometer example for your device, and click the Calibrate button. This will open the Compass Calibration tool.

2. If your device supports heating, we recommend checking the HeatingEnabled checkbox. Wait for the temperature reading to turn green:

If your Spatial does not support heating (neither of the above controls will be available), you can skip this step.

3. Next, decide if you're using 2-axis or 3-axis calibration:

● If the spatial is free to move in all directions, use 3-axis

● If the spatial is being kept mostly level (e.g. in a car), use 2-axis

4. You can leave the Local Field Strength at 1.0 for general use since magnitude doesn't affect heading. If you need more quantitative results, look up your local value.

5. Make sure your Phidget Spatial is firmly in the position you intend to calibrate it for, and begin by clicking the Start button.

Begin rotating the structure your Phidget is mounted to. Notice the red dots appearing on the graph.

6. Try to rotate it so that it fills out as much of the sphere (or circle in 2-axis mode) as possible. When you're finished, click Stop.

You should now see red and green spheres (or circles) in the graph. The red one is the raw measurements, and the green one is the calibrated measurements.

Newly calibrated data from the magnetometer will be indicated by a green line that matches the sphere. The green sphere should be more centered than the red one. If not, try repeating the calibration.

You're now done the calibration process! On most Phidget Spatials, the calibration will be stored in flash, so it stays calibrated to this environment even across power cycles.

7. If you need to repeat this exact calibration, you can save the values listed in the text box.

You can use these values in the setMagnetometerCorrectionParameters method. See our API Documentation for more details.
