The OLED display needs to be initialized. Please make sure you

• add a reference to AUG.AMI.Hardware
• add using AUG.AMI.Hardware
• instantiate the OLED_SPI class

The following sample will display a white cross on the screen:

using System;
using Microsoft.SPOT;

using System.Threading;
using AUG.SPOT.Hardware;

namespace DisplayTest
{
    public class Program
    {
        public static void Main()
        {
            OLED_SPI display = new OLED_SPI(true);

            Bitmap view = new Bitmap(480, 272);
            view.DrawLine(Microsoft.SPOT.Presentation.Media.Color.White, 1, 0, 0, 480, 272);
            view.DrawLine(Microsoft.SPOT.Presentation.Media.Color.White, 1, 0, 272, 480, 0);
            view.Flush();

            Thread.Sleep(-1);
        }
    }
}
