Language - C Sharp

We provide support for the C# language in all major operating systems. We also provide instructions on how to get your project started in a number of common development environments. Select your operating system and preferred development environment below, and follow the instructions to get your project running with Phidgets.

If you do not know which development environment you want to use, or your development environment of choice is not listed, we recommend starting with .NET CLI as the simplest path to getting your code running. Visual Studio is the most popular way to build C# projects, but it also has a steep learning curve.

Once you have set up your development environment to run with Phidgets, we recommend you follow our guide on Phidget Programming Basics. The guide will showcase the fundamentals of programming with Phidgets, with examples in C#.

Language - C#

Windows with Visual Studio

Welcome to using Phidgets with C#! By using C#, you will have access to the complete Phidget22 API, including events.

Visual Studio is an IDE provided by Microsoft that can be used to develop code in a wide variety of programming languages, including C#.

Requirements

First, make sure you have the following installed:

● Phidgets Drivers for Windows

● Microsoft Visual Studio

Nuget

The Phidget22.NET library is now available on nuget.org here. Nuget is the recommended way to install and use the .NET library in Visual Studio. The nuget package bundles the C library on Windows, so there are no other prerequisites that need to be installed. The nuget package adds targets for .NET Core and .NET Standard, so it should be usable from almost any .NET environment which also supports the C library.

Using Phidgets in Your Programs

There are two ways you can use Phidgets in Visual Studio. You can either start from a sample project provided by our code sample generator, or you can start a new project from scratch.

Select your preferred method below for instructions:

Setting up a New Project

When you are building a project from scratch, or adding Phidget functionality to an existing project, you'll need to configure your development environment to properly link the Phidget .NET library.

The easiest way to allow Mono to access the Phidgets .NET library is to place a copy of the Phidget22.NET dll in the same folder as your program.

First, determine which version of the .NET Framework your version of Mono implements by checking the Mono Release Documentation.

Next, download the Phidget22 Development Libraries, which contain dlls for each .NET version.

Navigate in the zip file to /lib/dotnet/netXX where 'XX' is your .NET Framework version (for example, net46 for .NET 4.6), and grab the Phidget22.NET.dll from that folder.

Setting up a New Project

Next, move the Phidget22.NET.dll you extracted into the same folder as your program.

Your folder should look somehting like this:

Compile and Run

Once you are ready to run your program, open the Command Prompt and navigate to your project folder. Next, enter the following command:

mcs /r:Phidget22.NET.dll Program.cs

This will create an executable file called Program.exe. Type in the following command to run the example:

mono Program.exe

Success! The project is now using Phidgets.

Language - C#

Linux with Mono

Welcome to using Phidgets with C#! By using C#, you will have access to the complete Phidget22 API, including events.

Mono is an open-source programming environment that aims to make Microsoft .NET applications available across all operating systems.

Requirements

First, make sure you have the following installed:

● Phidgets Drivers for Linux

● Mono

● A copy of Phidget22.NET.dll

You need our C development libraries in order to use Mono. You can install them with:

apt-get install libphidget22-dev

If you don't already have Mono installed, you can get it with:

apt-get install mono-complete

Setting UDev Rules

By default, Linux will not allow regular users to access physical hardware, as a security feature. This means that you must grant yourself root privileges via sudo to run Phidgets code.

sudo mono program.exe

To avoid having to use sudo every time, you can set up a rules file to allow it automatically using the vendor code for Phidget USB devices. Create a text file called 99-libphidget22.rules containing the following line:

SUBSYSTEMS=="usb", ACTION=="add", ATTRS{idVendor}=="06c2", ATTRS{idProduct}=="00[3-a][0-f]", MODE="666"

Mode 666 means every user has permission to read and write to the specified devices. Next, move this file to /etc/udev/rules.d. Now you can run code that uses Phidgets as a regular user without sudo.

Finding Code Samples

To find the code sample to use for your Phidget, navigate to the Code Samples page and select your device from the drop-down menu.

Once you select your device, the code sample generator will give you a working code sample, and a selection of options to customize it to your needs.

Language - C#

Linux with dotnet CLI

Welcome to using Phidgets with C#! By using C#, you will have access to the complete Phidget22 API, including events.

The dotnet command-line interface is the quickest way to start programming in C#.

Setting UDev Rules

By default, Linux will not allow regular users to access physical hardware, as a security feature. This means that you must grant yourself root privileges via sudo to run Phidgets code.

sudo dotnet run

To avoid having to use sudo every time, you can set up a rules file to allow it automatically using the vendor code for Phidget USB devices. Create a text file called 99-libphidget22.rules containing the following line:

SUBSYSTEMS=="usb", ACTION=="add", ATTRS{idVendor}=="06c2", ATTRS{idProduct}=="00[3-a][0-f]", MODE="666"

Mode 666 means every user has permission to read and write to the specified devices. Next, move this file to /etc/udev/rules.d. Now you can run code that uses Phidgets as a regular user without sudo.

Installing dotnet CLI

For installation instructions, visit Microsoft's documentation and select your Linux distro.

Usually, this will involve adding Microsoft packages to your repository and then installing dotnet via apt-get.

If you are a Visual Studio Code user, you can get the '.NET Install Tool' extension instead of installing manually.

Setting up a New Project

Create a new C# project using the following command:

dotnet new console -o helloworld

This will create a new C# console application in a folder named helloworld in your current directory. Next, enter the folder and type:

dotnet run

If everything installed properly, the application should build and you'll see 'Hello, World!' printed in the terminal.

Getting Phidgets Sample Code

Next we'll use this base project to run some Phidgets sample code. Go to the product page for your Phidget and go to the Code Samples tab. Select C# from the language drop-down and use the check boxes to modify the example if you'd like.

Click the copy button in the corner of the code sample and paste it into the Program.cs for your HelloWorld program, overwriting the existing code.

Compile and Run

Once you've pasted the sample code into the .cs file and saved, you need to add the Phidgets .NET package to your project:

dotnet add package Phidget22.NET

Then you can re-build the project using

dotnet run

Success! The project is now using Phidgets.

The dotnet command-line interface is the quickest way to start programming in C#.

Installing dotnet CLI

If you plan on using any USB Phidgets that use the HID stack, you'll need to install the Phidget drivers for MacOS. You can check which stack your USB Phidgets use by checking the 'USB Stack' in the product specifications. If all of your Phidgets use the PHIDUSB stack, you can skip installing the drivers.

Next, visit Microsoft's .NET page and download .NET after confirming compatibility with your version of MacOS.

Click on the .pkg file once it's finished downloading, and follow the steps to install the .NET SDK.

If you are a Visual Studio Code user, you can get the '.NET Install Tool' extension instead of installing manually.

Setting up a New Project

Open Finder and go to Utilities -> Terminal. Create a new C# project using the following command:

dotnet new console -o helloworld

This will create a new C# console application in a folder named helloworld in your current directory. Next, type cd helloworld to enter the folder, and type:
