| 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.

| | |
| ==Use Our Examples==
| |
| One of the best ways to start programming with Phidgets is to use our example code as a guide. In order to run the examples, you will need to download and install [http://www.mono-project.com/download/ Mono] for macOS. You will also need a copy of [{{SERVER}}/downloads/phidget22/libraries/windows/Phidget22-windevel.zip Phidget22.NET.dll].
| |
| | |
| | |
| Now that you have Mono installed and Phidget22.NET.dll on hand, download and unpack the HelloWorld example for C#:
| |
| *[{{SERVER}}/downloads/phidget22/examples/dotnet/csharp/Manager/Phidget22_HelloWorld_CSharp_Windows_Ex.zip HelloWorld example download]
| |
| Note: The HelloWorld example is compatible with Mono because it does not use Windows Forms. All other C# examples use Windows Forms.
| |
| | |
| | |
| Finally, you need to create a configuration file. Create a new file in the same directory as the example you wish to compile and name it Phidget22.NET.dll.config. Copy the content below to the file.
| |
| | |
| <syntaxhighlight lang='xml'>
| |
| <configuration>
| |
| <dllmap dll="phidget22.dll" target="/Library/Frameworks/Phidget22.framework/Versions/Current/Phidget22" />
| |
| </configuration>
| |
| </syntaxhighlight>
| |
| | |
| Your project directory should now look like this:
| |
| | |
| | |
| [[Image:Csharp_macos_mono_folder.png|link=|center]]
| |
| | |
| | |
| To compile the program, enter the following command in the terminal:
| |
| | |
| <syntaxhighlight lang='bash'>
| |
| mcs Program.cs -r:Phidget22.NET.dll
| |
| </syntaxhighlight>
| |
| | |
| An executable file will be created. Run the program using mono:
| |
| <syntaxhighlight lang='bash'>
| |
| mono Program.exe
| |
| </syntaxhighlight>
| |
| | |
| | |
| [[Image:Csharp_macos_mono_run.png|link=|center]]
| |
| | |
| | |
| You should now have the example up and running for your device. Play around with the device and experiment with some of the functionality. When you are ready, the next step is editing the examples with your own code!
| |
| | |
| ==Editing the Examples==
| |
| With the exception of the HelloWorld example mentioned earlier, the C# examples are what comprise the Windows [[Phidget Control Panel]]. These are all graphical examples, and Mono is a non-graphical environment so you'll need to modify a few things to adapt them for your own purposes. Start with copying the contents of '''Form1_Load''' from one of the examples into your mono program's main function.
| |
| | |
| Next, you can remove the following line:
| |
| <syntaxhighlight lang='CSharp'>
| |
| commandLineData phidgetParameters = open.parseCmdLine(); //get command line parameters
| |
| </syntaxhighlight>
| |
| | |
| Then, you can modify any line that mentions <code>phidgetParameters</code> by setting it to the desired value instead of using PhidgetParameters object.
| |
| | |
| For instance:
| |
| <syntaxhighlight lang='CSharp'>
| |
| try
| |
| { //set all the values grabbed from command line. these values have defaults that are set in ExampleUtils.cs, you can check there to see them.
| |
| digout.Channel = phidgetParameters.Channel; //selects the channel on the device to open
| |
| digout.DeviceSerialNumber = phidgetParameters.SerialNumber; //selects the device or hub to open
| |
| digout.HubPort = phidgetParameters.HubPort; //selects the port on the hub to open
| |
| digout.IsHubPortDevice = phidgetParameters.isHubPortDevice; //is the device a port on a VINT hub?
| |
| | |
| if (phidgetParameters.isRemote) //are we trying to open a remote device?
| |
| {
| |
| digout.IsRemote = true;
| |
| Net.EnableServerDiscovery(ServerType.Device); //turn on network scan
| |
| if (phidgetParameters.Password != null && phidgetParameters.ServerName != null)
| |
| Net.SetServerPassword(phidgetParameters.ServerName, phidgetParameters.Password); //set the password if there is one
| |
| }
| |
| else
| |
| digout.IsLocal = true;
| |
| | |
| digout.Open(); //open the device specified by the above parameters
| |
| }
| |
| catch (PhidgetException ex) { errorBox.addMessage("Error opening device: " + ex.Message); }
| |
| </syntaxhighlight>
| |
| | |
| Might become:
| |
| | |
| <syntaxhighlight lang='CSharp'>
| |
| try
| |
| {
| |
| digout.Channel = 0;
| |
| digout.DeviceSerialNumber = 370097;
| |
| digout.HubPort = 0;
| |
| digout.IsHubPortDevice = true;
| |
| digout.IsRemote = false;
| |
| digout.Open();
| |
| }
| |
| catch (PhidgetException ex) { errorBox.addMessage("Error opening device: " + ex.Message); }
| |
| </syntaxhighlight>
| |
| | |
| | |
| You'll also have to remove some references to graphical elements such as {{Code|ErrorEventBox}}. If you assign event handler functions, you'll have to define them before your main function, similar to the manager events in the HelloWorld example we covered earlier.
| |
| | |
| You can then manipulate the rest of the code as your application requires. A more in-depth description of programming with Phidgets will be covered in the next section.

| | |
| ==Setting up a New Project==
| |
| When you are building a project from scratch, or adding Phidget functionality to an exisiting project, you'll need to configure your development environment to properly link the Phidget .NET library.
| |
| | |
| To include the Phidget .NET library, simply add the following lines to the top of your code:
| |
| <syntaxhighlight lang='CSharp'>
| |
| using Phidget22;
| |
| using Phidget22.Events;
| |
| </syntaxhighlight>
| |
| | |
| Then, proceed to add your code to your main function.
| |
| | |
| Next, place a copy of Phidget22.NET.dll into the same directory as your program.
| |
| | |
| Finally, you need to create a configuration file. Create a new file in the same directory and name it Phidget22.NET.dll.config. Copy the content below to the file.
| |
| | |
| <syntaxhighlight lang='xml'>
| |
| <configuration>
| |
| <dllmap dll="phidget22.dll" target="/Library/Frameworks/Phidget22.framework/Versions/Current/Phidget22" />
| |
| </configuration>
| |
| </syntaxhighlight>
| |
| | |
| Your project directory should now look like this:
| |
| | |
| | |
| [[Image:Csharp_macos_mono_folder.png|link=|center]]
| |
| | |
| Open the command prompt at the directory location and enter the following command:
| |
| <syntaxhighlight lang='bash'>
| |
| mcs Program.cs -r:Phidget22.NET.dll
| |
| </syntaxhighlight>
| |
| | |
| This will create an executable file called ''Program.exe''. Type in the following command to run your program:
| |
| <syntaxhighlight lang='bash'>
| |
| mono Program.exe
| |
| </syntaxhighlight>
| |
| | |
| Success! The project now has access to Phidgets.
