## Step 1: Install Phidgets Library

1. First, you need to install the libusb-1.0 development libraries. For example, in Debian based distributions:

apt-get install libusb-1.0-0-dev

You’ll also need a C compiler and builder, if you don’t already have one installed.

apt-get install gcc
apt-get install make

## Step 1: Install Phidgets Library

3. Use the following commands in the location you unpacked to install the library:

./configure
make
sudo make install

## Step 1: Install Phidgets Library

4. (Optional) You can also download and unpack the following optional packages:

phidget22networkserver - Phidget Network Server, which enables the use of Phidgets over your network

phidget22admin - Admin tool to track who is connected to your Phidgets when using the network server

libphidget22extra - Required for phidget22networkserver and phidget22admin

libphidget22java - The Java libraries for Phidget22

For installation instructions for these packages, see the README file included with each one.

## Step 2: Connect Devices

● Connect USB Cable to your Linux Computer

● Connect VINT Device(s)

## Step 3: Verify Connection

1. The easiest way to verify that your libraries are working properly is to compile and run an example program. Download and unpack this C example that will detect any Phidget:

## Step 3: Verify Connection

2. Next, open the terminal in the location where you unpacked the example. Compile and run using:

gcc HelloWorld.c -o HelloWorld -lphidget22
sudo ./HelloWorld

ou should receive a “Hello” line for each Phidget channel that is discovered:

I don’t see any Phidgets show up in the HelloWorld example

You need to run it with sudo in order to be able to access USB devices. In order to use Phidgets without sudo, you need to set your udev rules. See the Advanced Information page on the final slide of this guide for details.

## Done!

## Part 2: Using Your Phidget

The VCP1002 allows you to measure voltages up to ±1V. This Phidget is ideal for small voltage monitoring applications. You can manually select the voltage range (±1V down to ±10mV) in your program to maximize resolution, or use Automatic mode which constantly adjusts the range based on the last voltage measurement.

### Explore Your Phidget Channels Using The Control Panel

1. Open your Control Panel, and you will find the 10-bit (±1V) Voltage Input Phidget channel:

2. Double click on the channel to open an example program. This channel belongs to the Voltage Input channel class:

10-bit (±1V) Voltage Input Phidget : Measures the voltage across the VCP1002’s terminals

In your Control Panel, double click on "10-bit (±1V) Voltage Input Phidget":

## Part 4: Advanced Topics and Troubleshooting

How do I know what channel, serial number, or hub port to use in my program?

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.

Setting the Change Trigger and Data Interval

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.

How can I plot or record sensor data?

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.

Isolation

The VCP1002 is electrically isolated. A power surge in the circuit being measured would only affect the VCP1002, so your VINT Hub or computer will remain unharmed. Having isolation also helps prevent the formation of ground loops in your system.

With isolation on the VCP1002, you can measure the voltage differential between two points of a circuit regardless of their relation to ground. The voltage differential between those points must be within the specification of the sensor.

For example, in the pictured battery charging circuit, there is sufficient complexity between the current sense resistor (Rsense) and VINT Hub that directly measuring the voltage with a non-isolated sensor could be a risky proposition. However, with VCP1002, the voltage across the resistor may be measured directly, ignoring the circuits in between.

Measuring the voltage across "Rsense" in this circuit is made easy through isolation!
Current Sense Resistors

The VCP1002 is made to measure small voltages anywhere in a circuit. As a result, the VCP1002 is ideal for use with current sense resistors to measure current. For an in-depth look at how to use current sense resistors with the VCP1002, see our article about Current Sense Resistors.
