Visual Studio Requirements

Windows IoT Extension for UWP extension is needed – right clicking on your project. Then, select Add > Reference.. 

Select Universal Windows > Exensions > Windows IoT Extension for the UWP, select the latest version and press OK

Add IO Pins Capability

(Includes adding SPI port, I2C port, etc capabilities)

To enable the IO pins open “Package.appxmanifest” > Capabilities Tab > Select “Low Level”

Namespace

using Windows.Devices.Gpio;

Using IO Pins

You can setup the IO pins in the App.xaml.cs OnLaunched() function no problem, but don’t set them up in the App() constructor

Defining your pins

	//IO PINS
	private GpioPin GpioPinMotorEnable;
	private GpioPin GpioPinMySwitch;

Initialising

	//------------------------------
	//----- INITIALISE IO PINS -----
	//------------------------------
	var gpio = GpioController.GetDefault();
	if (gpio == null)
	{
		//ERROR
		return;
	}

	GpioPinMotorEnable = gpio.OpenPin(17);					//<<<RPi GPIO## Pin number
	GpioPinMotorEnable.Write(GpioPinValue.Low);
	GpioPinMotorEnable.SetDriveMode(GpioPinDriveMode.Output);

	GpioPinMySwitch = gpio.OpenPin(18);                     //<<<Rpi GPIO## Pin number
	GpioPinMySwitch.SetDriveMode(GpioPinDriveMode.Input);

Setting Output Pins

	GpioPinMotorEnable.Write(GpioPinValue.Low);

	GpioPinMotorEnable.Write(GpioPinValue.High);

Reading Input Pins

	if (GpioPinMySwitch.Read() == GpioPinValue.High)
	{
	}
