Getting Started

Welcome to the 1056 user guide! In order to get started, make sure you have the following hardware on hand:

• 1056 PhidgetSpatial 3/3/3
• USB cable and computer

Next, you will need to connect the pieces:

1. Connect the PhidgetSpatial to your computer using the USB cable.

Now that you have everything together, let's start using the 1056!

Using the 1056

Phidget Control Panel

In order to demonstrate the functionality of the 1056, the Phidget Control Panel running on a Windows machine will be used.

The Phidget Control Panel is available for use on both macOS and Windows machines.

Windows

To open the Phidget Control Panel on Windows, find the icon in the taskbar. If it is not there, open up the start menu and search for Phidget Control Panel

macOS

To open the Phidget Control Panel on macOS, open Finder and navigate to the Phidget Control Panel in the Applications list. Double click on the icon to bring up the Phidget Control Panel.

For more information, take a look at the getting started guide for your operating system:

• Getting started with Windows
• Getting started with macOS

Linux users can follow the getting started with Linux guide and continue reading here for more information about the 1056.

First Look

After plugging the 1056 into your computer and opening the Phidget Control Panel, you will see something like this:

The Phidget Control Panel will list all connected Phidgets and associated objects, as well as the following information:

• Serial number: allows you to differentiate between similar Phidgets.
• Channel: allows you to differentiate between similar objects on a Phidget.
• Version number: corresponds to the firmware version your Phidget is running. If your Phidget is listed in red, your firmware is out of date. Update the firmware by double-clicking the entry.

The Phidget Control Panel can also be used to test your device. Double-clicking on an object will open an example.

Accelerometer

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

General information about the selected object will be displayed at the top of the window. You can also experiment with the following functionality:

• Modify the change trigger and/or data interval value by dragging the sliders. For more information on these settings, see the data interval/change trigger page.
• The measured values reported in g-force can be seen via labels as well as graphical dials. Try tilting the 1056 in different directions to see the labels and graphics change.
• An extremely accurate timestamp is also reported with the g-force values.

Magnetometer

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

General information about the selected object will be displayed at the top of the window. You can also experiment with the following functionality:

• Modify the change trigger and/or data interval value by dragging the sliders. For more information on these settings, see the data interval/change trigger page.
• Use the Set Params... button to set the calibration parameters. For more information about calibration, see the technical section.
• The measured values reported in Gauss can be seen via labels as well as a graphical diagram. The diagram can help you visualize the magnetic field vector.
• An extremely accurate timestamp is also reported with the Gauss values.

Gyroscope

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

General information about the selected object will be displayed at the top of the window. You can also experiment with the following functionality:

• Modify the change trigger and/or data interval value by dragging the sliders. For more information on these settings, see the data interval/change trigger page.
• The Zero Gyro button is used to compensate for the drift that is inherent to all gyroscopes. The gyroscope primer has more information about this subject.
• The measured values reported in degrees per second can be seen via labels as well as graphical dials. Try rotating the 1056 in different directions to see the labels and graphics change.
• An extremely accurate timestamp is also reported with the g-force values.

Spatial

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

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.

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.

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.

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

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 1056 device. 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 1056 device, 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 1056 device cannot be easily calibrated out.

Magnetic field data will become unavailable for ~28ms every 2 seconds as the compass perform internal calibrations. During this time, polling the magnetic field will return EPHIDGET_UNKNOWNVAL, or throw an UNKNOWNVAL exception. The magnetic field data in the SpatialData event will equal PUNK_DBL.
