9. Hello World OutputPort led = new OutputPort(Meridian.Pins.GPIO5, true); while (true) { Thread.Sleep(5000); led.Write(!led.Read()); }

10. DEMO The development process

12. GPIO and Interrupts pin = new InterruptPort(Tahoe.Pins.SW9, true, Port.ResistorMode.PullUp, Port.InterruptMode.InterruptEdge); pin.OnInterrupt += Pin_OnInterrupt; pin = new InputPort(Tahoe.Pins.SW9, Port.ResistorMode.PullUp); bool state = pin.Read(); pin = new OutputPort(Tahoe.Pins.SW9, true, Port.ResistorMode.PullDown); pin.Write(true); InputPort OutputPort InterruptPort

14. Drawing Primitives Bitmap bmp = new Bitmap(SystemMetrics.ScreenWidth, SystemMetrics.ScreenHeight); bmp.DrawRectangle( red, // outline colour 10, // outline thickness 20, 30, // x, y 40, 50, // width, height 0, // xCornerRadius 0, // yCornerRadius 0, 0, 0, 0, 0, 0, 0); bmp.Flush(); // copy bitmap to LCD
