Before you open a Phidget channel in your program, you can set these properties to specify which channel to open. You can find this information through the Control Panel.

1. Open the Control Panel and double-click on the red map pin icon:

2. The Addressing Information window will open. Here you will find all the information you need to address your Phidget in your program.

See the Phidget22 API for your language to determine exact syntax for each property.

In the Phidget Control Panel, open the channel for your device and click on the icon next to the data type that you want to plot. This will open up a new window:

If you need more complex functionality such as logging multiple sensors to the same sheet or performing calculations on the data, you'll need to write your own program. Generally this will involve addressing the correct channel, opening it, and then creating an Event Handler and adding graphing/logging code to it.

The quickest way to get started is to download some sample code for your desired programming language and then search google for logging or plotting in that language (e.g. "how to log to csv in python") and add the code to the existing change handler.

The Change Trigger is the minimum change in the sensor data needed to trigger a new data event. The Data Interval is the time (in ms) between data events sent out from your Phidget. You can modify one or both of these values to achieve different data outputs. You can learn more about these two properties here.

In order to get numbers of useful accuracy from the MOT1101's compass you will need to provide calibration parameters. To make determining them easy, we distribute a program with our drivers that does this for you.

To calibrate your compass:

• Navigate to the Phidgets installation folder on your computer. Open the 'examples' folder and find the Compass Calibrator program.

• Start the program and find the link in the Settings/Status text box. Go to the website listed. ([1])

• Select your country and city. Click 'Get Location' and then 'Compute'. A table of values will show up in an overlaid window. The value you will need is the 'Total Field' value in nT.

• Enter the magnetic field value into the calibration program. Note that it wants the field strength in Gauss, not nT like the website gives you. 1T = 10000 Gauss so you can divide by 1x10^5 to convert to Gauss.
• If you are intending on mounting the MOT1101 onto a large vehicle, such as a car, you should mount the 1056 securely to the vehicle in its final intended position then check the 2-axis bubble, click the 'Start' button.
• If you are using a smaller, more easily handled vehicle such as a small robot (something you could physically pick up) you will mount the MOT1101 and use the 3-axis calibration instead. Click 'Start'.

• Rotate the compass around (including attached equipment) such that the red dots being generated on screen outline a full sphere (in 3-axis). This will take several minutes. Your results may not generate an exact sphere -- but should be close to a sphere. Once done, click stop.
• If you are in a large vehicle, you will be aiming to fill out a disc instead of a sphere. This can be done by simply driving around for a few minutes making sure to do complete 360° turns in the process.

• Take the parameters displayed in the text box and use them for your compass. For example in C#:

 
     setCompassCorrectionParameters(0.51075, 0.18820, -0.07456, -0.02209, 1.87163, 1.87640, 2.12565, -0.04000, -0.04084, -0.03552, 0.09073, -0.04258, 0.11056);
