SPIDER + Display T35 : WPF : Text.ForeColor = Colors.Green; doesn't work (White, Yellow, Cyan are OK)


I’ve a problem to display green textes with NinaB font : White, Yellow, Cyan are OK but not Green !

Definition of Textes

[b] #region Creation Line PowerSupply
/* PowerSupply */
str_Text_Line_02_Text_01 =
new Text(Resources.GetFont(Resources.FontResources.NinaB), "PowerSupply : ");
str_Text_Line_02_Text_01.TextAlignment = TextAlignment.Left;
str_Text_Line_02_Text_01.ForeColor = Colors.Cyan;
Canvas.SetLeft(str_Text_Line_02_Text_01, 0);
Canvas.SetTop(str_Text_Line_02_Text_01, int_Height_Line_02);

        /* OK/AL */
        str_Text_Line_02_Text_02 =
            new Text(Resources.GetFont(Resources.FontResources.NinaB), "??");
        str_Text_Line_02_Text_02.TextAlignment = TextAlignment.Left;
        str_Text_Line_02_Text_02.ForeColor = Colors.White;
        Canvas.SetLeft(str_Text_Line_02_Text_02, 100);
        Canvas.SetTop(str_Text_Line_02_Text_02, int_Height_Line_02);
        #endregion Creation Line PowerSupply<Fin>[/b]

My timer is checking Status

[b] #region Methode Evenementielle du Timer
void GEPp_Timer_Display_001_Tick(GT.Timer timer)
/* Updating Dates*/
str_Text_Line_01_Text_02.TextContent = DateTime.Now.ToString(“yyyy’_'MMdd”);
str_Text_Line_01_Text_04.TextContent = DateTime.Now.ToString(“HH’:‘MM’:'ss”);

        /* Displaying Status*/
        if (bool_PowerSupply == false)
            str_Text_Line_02_Text_02.ForeColor = Colors.Yellow;    
            str_Text_Line_02_Text_02.TextContent = "AL";

str_Text_Line_02_Text_02.ForeColor = Colors.White; // Working :stuck_out_tongue:
bold]/str_Text_Line_02_Text_02.ForeColor = Colors.Green;/[/b] // Doesn’t Work !!! :frowning:
str_Text_Line_02_Text_02.TextContent = “OK”;
/Next code taken off for clarity/
#endregion Methode Evenementielle du Timer

If I use str_Text_Line_02_Text_02.ForeColor = Colors.White; OK appears in White,
If I use str_Text_Line_02_Text_02.ForeColor = Colors.Yellow; OK appears in Yellow,
If I use str_Text_Line_02_Text_02.ForeColor = Colors.Cyan; OK appears in Cyan,

If I use str_Text_Line_02_Text_02.ForeColor = Colors.Green; Nothing appears at all ??

P.S. : Version of course

If you display a full color image then will it look right or it will look like missing colors?

I have 6 Icone, 3 of them have green Colors and it is displayed correctly.
No problem with green pictures

textes in Green Color are very useful to indicate normal status on Display …

[italic]SOLVED :


It seams to be a bug of the SPIDER’s SDK :

Doesn’t Work :
str_Text_Line_02_Text_02.ForeColor = Colors.Green;

Works perfectly well on T35 display:

str_Text_Line_02_Text_02.ForeColor = ColorUtility.ColorFromRGB(0x00, 0xFF, 0x00); //Lime


static Color myLime_Color = ColorUtility.ColorFromRGB(0x00, 0xFF, 0x00);

str_Text_Line_02_Text_02.ForeColor = myLime_Color; //Lime
str_Text_Line_02_Text_02.TextContent = “OK”;

str_Text_Line_02_Text_03.ForeColor = myLime_Color; //Lime
str_Text_Line_02_Text_03.TextContent = “Running”;

For who wants to have ALL RGB colors, if it can help somebody…:

Thanks. We will look into this. i think this is a bug int eh gadgeteer core


Can you please provide a complete yet simple example that shows this error? We are no able to reproduce on our end.

Sorry for Delay,
I will simplify the project & send it by eMail to you…
PS: it is a part of an professionnal project, some icons are copyrighted, Please do not transmit the project,

Switching On and Off the Button on Slot_8 will generate Yeelow or Lime texte (AL or OK)

I’ve bought FEZHydra to test if my display’s bug persists, (and also for test)
But I can’t deploy it to FEZHydra (?)

FEZHydra is powered & OnBoard Led is flashing but :
VS2010 Prof. can’t deploy even a simple application as : Debug.Print(“Program Started”); (the default program).

It detects FEZHydra [Transport : USB Device : FEZ Hydra_FEZHydra ]
But : I’ve a deployment error ! :
Error 1 An error has occurred: please check your hardware.

What did I make as mistake ?

I’ve started MF Deployment Tool & erased FEZHydra : It did it correctly (
Cannot find any entrypoint!
Waiting for debug commands…
Now, the LED does not flash any more, but still :
Error 1 An error has occurred: please check your hardware.

(Can you also send me a link to send you the simple Display projet with my bug?)

There is know issue with USB on hydra that is fixed already and SKD will be out in few days to cover it and many other improvements.

Hello again,
Concerning my display’s bug : This is really a problem with Green color ! :
As I’m devopping WPF projects for PC, I’ve replaced :
Colors.Green by Utility.ColorFromRGB(0x00, 0xFF, 0x00) which is not green but Lime, a color I’m using currently…

I tried with real equivalent Green color : ColorUtility.ColorFromRGB(0x00, 0x80 , 0x00); //Green it doen’t work same than Colors.Green !!!

To sum up :
Doesn’t Work on T35 display:
str_Text_Line_02_Text_02.ForeColor = Colors.Green;
str_Text_Line_02_Text_02.ForeColor = ColorUtility.ColorFromRGB(0x00, 0x80 , 0x00); //Green

Works perfectly well on T35 display:
str_Text_Line_02_Text_02.ForeColor = ColorUtility.ColorFromRGB(0x00, 0xFF, 0x00); //Lime

Thanks for answer with USB hydra’s problem, I will wait…

Isn’t this green? So you see lime instead? This will be easy once you compare to hydra. Maybe there is a hardware problem.

I tried with a standard WPF appl .Net Framework for PC :
On a black window’s background :
Green is very dark compare to Lime which is a “light” green.

On T35 display .NETMF :
Lime is very clear & “very visible” but Green is not visible at all independly of the instruction : ColorUtility.ColorFromRGB(0x00, 0x80 , 0x00) is not better than Colors.Green;
