G-Sensor Programmierung

Hallo,
ich habe folgende Problemstellung, ich moechte mir eine Bluetooth Fernbedienung Programmieren die mittels Bewegung und einigen wenigen Tasten funktioniert.

Das eigentliche Problem ist nun der G-Sensor, um genauer zu sein die Daten des Sensors zu lesen, das Auswerten sollte eigentlich kein Problem sein, ist hier evt. jemand der Erfahrung hat oder einen Link empfehlen kann, SDK etc.? Bin dankbar fuer jegliche Hilfe. Programmiersprache sollte C++ sein, ungern aber moeglich waere auch C#.

Vielen Dank schonmal im Vorraus.

Guck mal hier:

http://blog.enterprisemobile.com/200...-managed-code/

Damit hab ich mal was programmiert (Visual Studio, .NET CF, C#), ging super...

Ich habe den Thread verschoben, hier würdest du mehr Antworten bekommen.

http://scottandmichelle.net/scott/co...html?entry=784 (Englisch) ist ein Beispielprojekt in C++.

Vielen dank fuer die schnelle Hilfe, hab gefunden wonach ich gesucht hab.

Denke es werden jetzt einige lange Naechte folgen ;)

Hallo,
ich versuche ebenfalls den G-Sensor auf einem HTC HD zu programmieren, finde bisher aber nichts dazu im .NET Compact Framework. Die bereits geposteten Links habe ich bereits gefunden, diese beziehen sich aber nur auf C#. Hat das jemand schon in VB realisiert?

Bis auf eine leicht andere Syntax sollte das genauso funktionieren!

Leicht andere Syntax? Ich weiß nicht mal, wie ich mit dem C# Code anfangen muss :(

Das C# Projekt gibt's hier (unter source code). Das enthält Code für die verschiedenen Sensoren für HTC und Omnia.
Da ich nur den G-Sensor für HTC Geräte brauche, habe ich die folgende Klasse erstellt:

Code:

---

using System;
using System.Runtime.InteropServices;

namespace GSensorTest
{
    public class GSensor : IDisposable
    {
        public struct SensorData
        {
            public short TiltX;          // From -1000 to 1000, 0 is flat
            public short TiltY;          // From -1000 to 1000, 0 is flat
            public short TiltZ;          // From -1000 to 1000, 0 = Straight up, -1000 = Flat, 1000 = Upside down
            public short Unknown1;
            public int AngleY;          // From 0 to 359 degrees
            public int AngleX;          // From 0 to 359 degrees
            public int Unknown2;
        };

        [DllImport("HTCSensorSDK")]
        extern static IntPtr HTCSensorGetDataOutput(IntPtr handle, out SensorData sensorData);

        [DllImport("HTCSensorSDK")]
        extern static IntPtr HTCSensorOpen(int sensor);

        [DllImport("HTCSensorSDK")]
        extern static void HTCSensorClose(IntPtr handle);

        [DllImport("coredll", SetLastError = true)]
        extern static IntPtr CreateEvent(IntPtr eventAttributes, bool manualReset, bool intialState, string name);

        [DllImport("coredll", SetLastError = true)]
        extern static bool EventModify(IntPtr handle, uint func);

        [DllImport("coredll")]
        extern static bool CloseHandle(IntPtr handle);

        private IntPtr _handle;

        public GSensor()
        {
            _handle = HTCSensorOpen(1);
            IntPtr hEvent = CreateEvent(IntPtr.Zero, true, false, "HTC_GSENSOR_SERVICESTART");
            EventModify(hEvent, 3);
            CloseHandle(hEvent);
        }

        public void GetSensorData(ref SensorData data)
        {
            HTCSensorGetDataOutput(_handle, out data);
        }

        #region IDisposable Members

        public void Dispose()
        {
            if (_handle != IntPtr.Zero)
            {
                HTCSensorClose(_handle);
                _handle = IntPtr.Zero;
            }
            IntPtr hEvent = CreateEvent(IntPtr.Zero, true, false, "HTC_GSENSOR_SERVICESTOP");
            EventModify(hEvent, 3);
            CloseHandle(hEvent);
        }

        #endregion
    }
}

Und für VB.net gibt's diverse freie Konvertierer (z.B. C# - VB.net Konvertierer)
Mit folgendem Resultat:

Code:

---

    Public Class GSensor

        Public Structure SensorData
            Public TiltX As Short

        #Region "IDisposable Members"
       
        Public Sub Dispose()
            If _handle <> IntPtr.Zero Then
                HTCSensorClose(_handle)
                _handle = IntPtr.Zero
            End If
            Dim hEvent As IntPtr = CreateEvent(IntPtr.Zero, True, False, "HTC_GSENSOR_SERVICESTOP")
            EventModify(hEvent, 3)
            CloseHandle(hEvent)
        End Sub
       
        #End Region
    End Class
End Namespace

Da der Emulator diesen Sensor nicht hat (die entsprechende dll fehlt natürlich auch), habe ich im code so etwas wie

Code:

---

private GSensor _gSensor;
...
// init
if (File.Exists(@"\Windows\HTCSensorSDK.dll"))
{
    _gSensor = new GSensor();
}
...
// get sensor data
if (_gSensor != null)
{
    GSensor.SensorData sensorData = new GSensor.SensorData();
    _gSensor.GetSensorData(ref sensorData);
}
...
// close application
if (_gSensor != null)
{
    _gSensor.Dispose();
}

Wow, cool! Ich werde es damit mal ausprobieren! Vielen Dank!

So, habe es nun endlich ausprobieren können und es funktioniert :)
Vielen Dank nochmal :)

Hallo,

könntet Ihr wohl ein Beispiel zum Download bereitstellen? Irgendwie bekomme ich das nicht hin.

Danke im Voraus!

Das ist die GSensor-API-Klasse in VB.NET, so wie ich sie gerade verwende:

Code:

---

Imports System
Imports System.Runtime.InteropServices

Public Class GSensor
    Implements IDisposable

    Public Structure SensorData
        Public TiltX As Short ' From -1000 to 1000, 0 is flat
        Public TiltY As Short ' From -1000 to 1000, 0 is flat
        Public TiltZ As Short ' From -1000 to 1000, 0 = Straight up, -1000 = Flat, 1000 = Upside down
        Public Unknown1 As Short
        Public AngleY As Integer ' From 0 to 359 degrees
        Public AngleX As Integer ' From 0 to 359 degrees
        Public Unknown2 As Integer
    End Structure

    <DllImport("HTCSensorSDK")> _
    Private Shared Function HTCSensorGetDataOutput(ByVal handle As IntPtr, ByRef sensorData As SensorData) As IntPtr
    End Function

    <DllImport("HTCSensorSDK")> _
    Private Shared Function HTCSensorOpen(ByVal sensor As Integer) As IntPtr
    End Function

    <DllImport("HTCSensorSDK")> _
    Private Shared Sub HTCSensorClose(ByVal handle As IntPtr)
    End Sub

    <DllImport("coredll", SetLastError:=True)> _
    Private Shared Function CreateEvent(ByVal eventAttributes As IntPtr, ByVal manualReset As Boolean, ByVal intialState As Boolean, ByVal name As String) As IntPtr
    End Function

    <DllImport("coredll", SetLastError:=True)> _
    Private Shared Function EventModify(ByVal handle As IntPtr, ByVal func As UInteger) As Boolean
    End Function

    <DllImport("coredll")> _
    Private Shared Function CloseHandle(ByVal handle As IntPtr) As Boolean
    End Function

    Private _handle As IntPtr

    Public Sub New()
        Dim hEvent As IntPtr

        Try
            _handle = HTCSensorOpen(1)

            hEvent = CreateEvent(IntPtr.Zero, True, False, "HTC_GSENSOR_SERVICESTART")
            EventModify(hEvent, 3)
            CloseHandle(hEvent)
        Catch
            MsgBox("This is not a HTC Device")
        End Try
    End Sub

    Public Sub GetSensorData(ByRef data As SensorData)
        If (_handle <> IntPtr.Zero) Then
            HTCSensorGetDataOutput(_handle, data)
        End If
    End Sub

    Public Sub Dispose() Implements System.IDisposable.Dispose
        Dim hEvent As IntPtr

        If (_handle <> IntPtr.Zero) Then
            HTCSensorClose(_handle)
            _handle = IntPtr.Zero
        End If

        hEvent = CreateEvent(IntPtr.Zero, True, False, "HTC_GSENSOR_SERVICESTOP")
        EventModify(hEvent, 3)
        CloseHandle(hEvent)
    End Sub
End Class
