Code Model

The basic bricks of the libiio API, and therefore the C# bindings are the the iio namespace, and the classes of that nameplace: iio.Channel, iio.Context, iio.Device, iio.IOBuffer, iio.Trigger, and iio.Attr (channel or device attributes).

Creating a context

Creating a context is quite easy with the iio.Context class:

Context ctx = new Context("ip:10.44.2.241");

Navigation

Device objects

foreach (Device dev in ctx.devices)
{
   Console.WriteLine("\t" + dev.id + ": " + dev.name);
}

Channel objects

Each iio.Channel can be either input, or output. This information can be retrieved with iio.Channel.output As for the Device objects, the iio.Channel object features an ID and optionally a name The ID can be obtained with iio.Channel.id, and the name can be obtained with iio.Channel.name. Important note: two iio_channel can have the same ID, as long as one is input and the other is output.

foreach (Channel chn in dev.channels)
{
    string type = "input";
    if (chn.output)
        type = "output";
    Console.WriteLine("\t\t\t" + chn.id + ": " + chn.name + " (" + type + ")");
}

Parameters

Different kinds of parameters are available: parameters that apply to a iio_device, and parameters that apply to one or more iio_channel.

for Channel attributes: iio.Channel.attrs

foreach (Attr attr in chn.attrs)
{
    Console.WriteLine("\t\t\t\t" + attr.name);
    if (attr.name.CompareTo("frequency") == 0)
    {
        Console.WriteLine("Attribute content: " + attr.read());
    }
}

For Device Attributes: iio.Device.attrs

foreach (Attr attr in dev.attrs)
   Console.WriteLine("\t\t\t" + attr.name);
