RaspberryPi Web LEDControl

This project enables you to control a LED stripe like Ws2812b over the web using a converter like FT232H breakout board or GPIO of Raspberry Pi.

Getting started

Install .NET 8

You can configure the project using appsettings.json:

{
  "HostingSettings": {
    "Port": "<WebServer Port>"
  },
  "LEDStripSettings": {
    "UseUsbConverter": <true/false>, // Set to True when FT232H is used, set to false when Raspberry Pi GPIO is used
    "UsbConverterId": <USB-ID>, // Set to USB Converter ID which is printed out on app start, set to null when Raspberry Pi GPIO is used
    "NumberOfLeds": <Number-Of-Leds> // Number of LEDs of your stripe
  }
}

Build and run

To build and run the application you have to:

Run dotnet restore then dotnet run
