Question about infinite frame

[zhusihan-python]

Halo:

I have frame data comes from a serial port, like every 200ms it received a heartbeat

// Heartbeat frame parsed to device property
public class Device : ObservableObject
{
    public ReactiveProperty<DeviceResetType> DeviceResetState { get; set; } = new(DeviceResetType.NotRest);

    public ReactiveProperty<SealMotorResetType> SealMotorResetState { get; set; } = new(SealMotorResetType.NotRest);

    public ReactiveProperty<ushort> ScanTargetIndex { get; set; } = new(0);

    public ReactiveProperty<ushort> ActionPackNumber { get; set; } = new(0);
    ...
}

i want to expose the data to the UI layer(views)，but the FrameProvider seems like a fixed size collections of data replay, how can I use a FrameProvider that can get new serial port data continuously, and push the data to views?

    void RunLoop()
    {
        var span = list.AsSpan();
        for (int i = 0; i < span.Length; i++)

What do you mean by "fixed size collections"?
Is the source code cut off in the middle?
I don't understand where this is intended to be used.
