G400HDR Developer Quick Start

The onboard LED on the G400HDR is located on Pin PD3. It is a user controllable GPIO.
The following is some code to get you started blinking your first LED on the G400HDR:


using System;
using System.Threading;
 
using Microsoft.SPOT;
using Microsoft.SPOT.Hardware;
 
using GHI.Hardware.G400;
 
namespace G400_Console_G400HDR_BlinkLED
{
    public class Program
    {
        public static void Main()
        {
            OutputPort G400HDR_LED = new OutputPort(Pin.PD3, false);
 
            while (true)
            {
                Thread.Sleep(250);
                G400HDR_LED.Write(!G400HDR_LED.Read());
            }
        }
 
    }
}

The above does not work if you are using dotnetwarrior.Gadgeteer.G400HDR.
The Pin.PD3 is reserved and you will receive an Exception.

In it’s place just use:



using System;
using Gadgeteer:

PulseDebugLED();

@ willgeorge - It does not work because Gadgeteer captures the LED pin to use for mainboard LED operations.
