Hi everyone,

I plugged the card gyro (L3G4200D) , with the controller NetDuino Plus
• when queried values of the gyro, the values are incorrect
• during interrogation of the identification values of the circuit, and temperature. The values are correct.

I2C bus is functional but for some reason unknown, the gyro seems not to work.
Have you ever encountered this problem?

Hello, how do you represent a binary number in c#?? I know for a hex number is = 0xffffffff but what about binary? Regards. Thierry

Hello,

Card: NetDuino Plus
Fonction : Use a microSd 2Go integrating on the Netduino Plus for Loader and exécute compiller program (pe)
Framework version: 4.2



Problem: Does not continue after "Assembly.Load(assmbytes)" .. not executed code loaded.. Help me please.

debug:
The debugging target runtime is loading the application assemblies and starting execution.
'Microsoft.SPOT.Debugger.CorDebug.dll' (Managé) : 'LedClignotte' load


Notes:
other soft for read file, write file in the microsd is ok.

namespace NetduinoPlusSdLoader
{
    public class Program
    {
        public static void Main(string[] args)
        {


            try
            {

                using (FileStream assmfile = new FileStream(@"SD\LedClignotte.pe", FileMode.Open, FileAccess.Read, FileShare.None))
                {
                    byte[] assmbytes = new byte[assmfile.Length];
                    assmfile.Read(assmbytes, 0, (int)assmfile.Length);
                    var assm = Assembly.Load(assmbytes);
                    var obj = AppDomain.CurrentDomain.CreateInstanceAndUnwrap("ASSM, Version=1.0.0.0", "ASSM.TestClass");
                    var type = assm.GetType("ASSM.TestClass");

                    MethodInfo mi = type.GetMethod("Print");

                    mi.Invoke(obj, null);
                }


            }
            catch (Exception ex)

        public static void Main()
        {
            // write your code here
            Thread flashLedThread = new Thread(flashLed);
            flashLedThread.Start();
            Thread.Sleep(Timeout.Infinite);
        }

        public static void flashLed()
