### Getting Started

Next, you will need to connect the pieces:

1. Connect the VINT Hub to your computer with a USB cable.
2. Connect the HIN1100 to the VINT Hub using the Phidget Cable.

Now that you have everything together, let's start using the HIN1100!.

## Using the HIN1100

### Phidget Control Panel

In order to demonstrate the functionality of the HIN1100, 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.

### First Look

After plugging the HIN1100 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 If your Phidget is listed in red, your firmware is out of date.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.

### Digital Input (Button)

Double-click on a Digital Input Button 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:

• You can click down on the middle of the thumbstick to activate the digital input.

### Voltage Ratio Input (Axis)

Double click on a Joystick Axis 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:

• At the top of the window, information about your device and the properties of this particular channel will be listed.
• On the left, change trigger and/or data interval can be changed. For more information on these settings, see the Data Rate/Change Trigger page.
• On the right, the voltage ratio is reported in volts per volt. In this case, a value of 1.0 corresponds to the maximum tilt in one direction of the axis, and a value of -1.0 corresponds to the maximum tilt in the other direction. Note: The stick will not be able to fully reach the -1.0 or 1.0 position while inside the enclosure.

### Joystick Axes

Each axis on the joystick is represented as its own VoltageRatioInput object. Axis 0 and Axis 1 are mapped to channels 0 and 1, respectively. You will have to open both channels to fully track the joystick's position.

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.

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

### Converting to Polar Coordinates

For some applications, you may want to convert the 2-axis data of the Thumbstick Phidget into an angle and magnitude. This can be helpful if you want to use it like a video game controller. You can use the following formulas:

${\displaystyle {\text{r}}={\sqrt {x^{2}+y^{2}}}}$
${\displaystyle \phi =atan2(x,y)}$

Where r is the magnitude, ϕ is the angle, and x and y are the two axis values. Atan2 is the 2-argument arctangent function, which you can find in most math libraries. For example, in C# you could use Math.Atan2(x,y). Depending on your language, ϕ may be in radians or degrees.

Since x and y range from -1.0 to 1.0, the resulting r will range from ${\displaystyle -{\sqrt {2}}}$ to ${\displaystyle {\sqrt {2}}}$, so you may also want to modify the first formula like so:

${\displaystyle {\text{r}}={\frac {\sqrt {x^{2}+y^{2}}}{\sqrt {2}}}}$

This way, your r will range from 0 to 1, which is more intuitive than ${\displaystyle -{\sqrt {2}}}$ to ${\displaystyle {\sqrt {2}}}$.

### Current Consumption

The current consumption of the HIN1100 depends on the data interval being used:
