Microsoft provides variations of Simple Blinky Programs. You find them under Samples or on GitHub.

Follow the Microsoft Samples for ARM systems (Raspberry Pi 2/ Dragon Board). On this page we point out the differences to the Microsoft Instructions.

Pin Numbering

If you have the Win 10 IoT Core Starter Kit you should also have the flyer with the pin numbers:

You will need to use the SODIMM Pinnumber to access the pin. Here is a C# code snippet, accessing SODIMM Pin number 98. On the Iris X16 this is pin number 13

        var gpio = GpioController.GetDefault();

        // Show an error if there is no GPIO controller
        if (gpio == null)
        {
            pin = null;
            GpioStatus.Text = "There is no GPIO controller on this device.";
            return;
        }

        pin = gpio.OpenPin(98);  //Here use the SODIMM Pinnumber
        pinValue = GpioPinValue.High;
        pin.Write(pinValue);
        pin.SetDriveMode(GpioPinDriveMode.Output);

Usable Pins

If you use another carrier board you can try to use other pins, but we have not yet tested all of them yet.
