Hello
I want to handle my display views using wpf. but after this line of code executed :
I get this error :
[quote]ERROR: You can only use WPF on one display (and if an LCD is present, only on the LCD)[/quote]
I've connect my n18 display to raptor mainboard on socket 11...
what is the problem?!The message says thet the LCD Controller is enabled and I guess WPF is bound to it by Default.
What Kind of Project do you have Gadgeteer or plain NETMF?
Check if a Display is configured for your raptor with FEZ Config.
Please post all your initialization code up to the line that Fails.
@ Reinhard Ostermeier -
no WPF is not bounded…
My project is Gadgeteer . and this is startup code :
public partial class Program : Gadgeteer.Program {
private Gadgeteer.Modules.GHIElectronics.UsbClientDP usbClientDP;
private Gadgeteer.Modules.GHIElectronics.Display_N18 display_N18;
private Gadgeteer.Modules.GHIElectronics.Button button;
private Gadgeteer.Modules.GHIElectronics.Button button2;
protected new static GHIElectronics.Gadgeteer.FEZRaptor Mainboard {
get {
return ((GHIElectronics.Gadgeteer.FEZRaptor)(Gadgeteer.Program.Mainboard));
}
set {
Gadgeteer.Program.Mainboard = value;
}
}
public static void Main() {
Program.Mainboard = new GHIElectronics.Gadgeteer.FEZRaptor();
Program p = new Program();
p.InitializeModules();
p.ProgramStarted();
p.Run();
}
private void InitializeModules() {
this.usbClientDP = new GTM.GHIElectronics.UsbClientDP(8);
this.display_N18 = new GTM.GHIElectronics.Display_N18(11);
this.button = new GTM.GHIElectronics.Button(18);
this.button2 = new GTM.GHIElectronics.Button(17);
}
}
public partial class Program
{
Font fnt = Resources.GetFont(Resources.FontResources.Tahoma16);
Image imgCapacity;
int imgCapacityX = 200;
int imgCapacityY = 5;
Window window;
Canvas canvas;
private CellularRadioManager _radioManager;
private readonly string _crlf = "" + (char)13 + (char)10;
void ProgramStarted()
{
SetUpWindow();
}
private void SetUpWindow()
{
window = display_N18.WPFWindow;
canvas = new Canvas();
window.Child = canvas;
imgCapacity = new Image(new Bitmap(Resources.GetBytes(Resources.BinaryResources.imgCapacity), Bitmap.BitmapImageType.Bmp));
canvas.Children.Add(imgCapacity);
Canvas.SetLeft(imgCapacity, imgCapacityX);
Canvas.SetTop(imgCapacity, imgCapacityY);
canvas.UpdateLayout();
window.UpdateLayout();
}
}
Hard to tell where this Comes from, but since Gadgeteer is open source you could look into the sources where and when this error is displayed.
Do you have, or have you had, a LCD display, like the TE35, attached to your mainboard? If so, reload the firmware. This will disassociate the LCD display from the board.
