Problem to use the I2CDevice on a FEZ panda II

I´m trying to use a 24lc32 EEPROM Memory on a FEZ Panda II board, but when I try to debug on the platform an exception occurs (An unhandled exception of type 'System.ArgumentException' occurred in Microsoft.SPOT.Hardware.dll

Can you help me to solve the problem?
mi code is:

using System;
using System.Threading;
using System.Text;
using Microsoft.SPOT;
using Microsoft.SPOT.Hardware;
using GHIElectronics.NETMF.FEZ;
using GHIElectronics.NETMF.Hardware;

namespace FTicketeraFez
    public class Program
        public static void Main()
            byte[] bBuffer = Encoding.UTF8.GetBytes("Prueba del Folio:   ");
            string sBuffer = "Prueba de Folio:   ";
            byte[] buf= new byte[2];
            byte[] bFolio = new byte[3]{0,0,0};
            bool LedState = false;
            byte[] lectura = new byte[1];
            string Numero;
            UInt16 Address = 0;
            //DateTime Fechahora = new DateTime(2014, 4, 21, 19, 02, 0);
            FTP_628DSL490R Printer = new FTP_628DSL490R("COM1");


            OutputPort Led = new OutputPort((Cpu.Pin)FEZ_Pin.Digital.LED, LedState);
            InputPort Botton = new InputPort((Cpu.Pin)FEZ_Pin.Digital.LDR, true, Port.ResistorMode.PullUp);
            I2CDevice.Configuration config = new I2CDevice.Configuration(0xA0, 100);
            I2CDevice idevice = new I2CDevice(config);

            byte[] buffer = new byte[] { 0xAA }; // dummy data
            I2CDevice.I2CWriteTransaction writeTransaction = I2CDevice.CreateWriteTransaction(buffer);

            I2CDevice.I2CTransaction[] trans = new I2CDevice.I2CTransaction[] { writeTransaction };

            int transfered = idevice.Execute(trans, 100);



            while (true)
                LedState = !LedState;

                if (Botton.Read() == false)
                    Numero = bFolio[0].ToString();
                    bFolio[0] += 1;
                    if (bFolio[0] == 10)
                        bFolio[0] = 0;





For those who can’t read the long scroll (everyone :)) here’s what the post says:

Panda II - so you’re targeting 4.1 framework, right? Can you confirm when the exception is thrown, as soon as your app is deployed or some time later? What are your references you’ve added?


The exception gets thrown on the I2C transaction execute line:


but the cause of the error is the I2C address being wrong.  A0 is not a valid I2C address. The address format of an 24LC32 in 7-bit I2C is 1010xxx where the last 3 x's represent the A0/A1/A2 pin settings. Assuming they're all 0's, your address is 0x50.

You can take a look at the I2C page on the documents sub-site here and see the very explicit 7-bit warning.
