Referencing Hid Library from GitHub library in C# and use it

Question

I am just starting to learn C# so excuse me if this is a basic question. I am trying to develop an application that reads values for a USB-HID scale into Excel. To start I am going to use this github library (already downloaded it): https://github.com/mikeobrien/HidLibrary then use closedxml.codeplex.com to create a spreadsheet and transfer data there.

I am trying to figure out how to reference this library in my C# project and use it to get information from the scale. I don't know much about C# or .NET and would love some help, most google searches haven't helped much so any leads would be much appreciated. Thank you!

Answer 1

The link you provided from GitHub specifies the name of the lib for referenced it on your project. Take a look at the Installation section. This code is for using on the Nuget Package Console on your project.

PM> Install-Package hidlibrary

Take a look on how to use the Nuget Package console for Visual Studio on this link https://docs.nuget.org/consume/package-manager-console

Answer 2

Try out Hid.Net

You can read about Hid transfer in the documentation here .

This reads from a thermometer which would probably be similar to scales.

Reference

    private static async Task DisplayTemperature()
    {
        //Connect to the device by product id and vendor id
        var temperDevice = await new FilterDeviceDefinition(vendorId: 0x413d, productId: 0x2107, usagePage: 65280)
            .CreateWindowsHidDeviceFactory(_loggerFactory)
            .ConnectFirstAsync()
            .ConfigureAwait(false);

        //Create the observable
        var observable = Observable
            .Timer(TimeSpan.Zero, TimeSpan.FromSeconds(.1))
            .SelectMany(_ => Observable.FromAsync(() => temperDevice.WriteAndReadAsync(new byte[] { 0x00, 0x01, 0x80, 0x33, 0x01, 0x00, 0x00, 0x00, 0x00 })))
            .Select(data => (data.Data[4] & 0xFF) + (data.Data[3] << 8))
            //Only display the temperature when it changes
            .Distinct()
            .Select(temperatureTimesOneHundred => Math.Round(temperatureTimesOneHundred / 100.0m, 2, MidpointRounding.ToEven));

        //Subscribe to the observable
        _ = observable.Subscribe(t => Console.WriteLine($"Temperature is {t}"));

        //Note: in a real scenario, we would dispose of the subscription afterwards. This method runs forever.
    }
