A .NET Library for the Pimoroni Unicorn HAT HD

A .NET library to drive the Pimoroni Unicorn HAT HD RGB LED matrix on the Raspberry Pi. This library and usage examples are based on Pimoroni's Python source code on GitHub.

Requirements

• A Raspberry Pi with the .NET 6 runtime installed on Linux.
• The Unicorn HAT HD connected to the Raspberry Pi.
• SPI enabled – see Manual install notes in the pimoroni/unicorn-hat-hd repository.

Usage

Create a new console application using the CLI command:

dotnet new console

Include the library with the command:

dotnet add package Mclift.UnicornHatHdDotnet

Edit Program.cs and change its contents to:

using Mclift.UnicornHatHdDotnet;

using var hat = new UnicornHat();
hat.SetAll(128, 0, 64);
hat.Show();
Console.WriteLine("Press RETURN to exit...");
Console.ReadLine();
hat.Off();

Run the sample with the following command, replacing /path/to/dotnet with the actual path to your .NET binary – you can find this by typing which dotnet:

sudo -E /path/to/dotnet run

The LED matrix should light up purple and then turn black again when you press RETURN.
