Step 3 - Install Meadow Project Templates

Open a console window and enter the following command to install a list of Meadow project templates:

dotnet new install WildernessLabs.Meadow.Template

When installed, you’ll see a list of templates available:

The following template packages will be installed:
   WildernessLabs.Meadow.Template

Meadow reTerminal App    meadow-reterminal   [C#]            Meadow/Console
Meadow StartKit App      meadow-startkit     [C#]            Meadow/App/StartKit

Step 4 - Add VS Linux Debugger Studio Extension

Open Visual Studio’s Extensions Manager and install the VS Linux Debugger Extension.

Make sure you go through their Getting Started instructions to properly configure the target device (reTerminal) and how to use the extension to build and deploy the Meadow.Linux application over the network.

Step 5 - Create your first Meadow application

In Visual Studio, open the Create a new project window. When you search for Meadow, you will see a list of project templates, click on Meadow.Linux reTerminal App (Wilderness Labs):

When this application runs, it'll show a 320x240 window in the center of the reTerminal's screen with a label saying Hello World using MicroLayout.

Step 6 - Run a Meadow Application

Once the application is deployed successfully, open a terminal on the reTerminal and go to inside the project's folder and type:

dotnet [Your Project Name].dll

The terminal will output a few console output strings in the MeadowApp and a GTK screen will appear in the center saying Hello World.

Step 4 - Create your first Meadow application

Lets verify everything is set up by deploying your first Meadow application.

Open VSCode and in a new Terminal within, enter the following command to create a new Meadow.Linux project that will run on your Raspberry Pi:

dotnet new meadow-reterminal --name reTerminalDemo

This Meadow.Linux application shows a basic Meadow app structure with an Initialize and Run methods with logging strings to confirm in the output the application ran successfully.

Step 5 - Run a Meadow Application

Lets run this application as is on your Raspberry Pi. In a terminal inside the project folder, build the project with the command:

dotnet build

And finally to run the Meadow application, use the command:

dotnet run

A GTK window should show up in the center of the screen saying Hello, World, like below:

And if you check the output you should see something like this:

Log level: Information
Platform does not support gpiod
Update Service is disabled.
Health Metrics disabled.
Initialize...
Run...
Hello, reTerminal!
