Dear All,
I have a FEZ Panda III board and a TFT 2.3 LCD Shied V3.
In forum support, .NET Micro Framework – GHI Electronics , I searched for a Panda III <===> Display Example and opted the “TOUCH” section. I tried to write the below code sample. And getting this error.
using System;
using Microsoft.SPOT;
using Microsoft.SPOT.Input;
using Microsoft.SPOT.Presentation;
using Microsoft.SPOT.Presentation.Media;
using Microsoft.SPOT.Touch;
namespace Micro_TFTDisplay
{
public class Program : Application
{
private Bitmap lcd;
public static void Main()
{
Debug.Print(Resources.GetString(Resources.StringResources.String1));
Program app = new Program();
app.Run();
}
public Program()
{
this.lcd = new Bitmap(SystemMetrics.ScreenWidth, SystemMetrics.ScreenHeight);
Touch.Initialize(this);
this.MainWindow = new Window();
this.MainWindow.TouchDown += MainWindow_TouchDown;
this.MainWindow.TouchUp += MainWindow_TouchUp;
this.MainWindow.TouchMove += MainWindow_TouchMove;
}
private void MainWindow_TouchMove(object sender, TouchEventArgs e)
{
Debug.Print("Touch move at (" + e.Touches[0].X.ToString() + ", " + e.Touches[0].Y.ToString() + ")");
this.lcd.DrawEllipse(Colors.Blue, e.Touches[0].X, e.Touches[0].Y, 5, 5);
this.lcd.Flush();
}
private void MainWindow_TouchUp(object sender, TouchEventArgs e)
{
Debug.Print("Touch up at (" + e.Touches[0].X.ToString() + ", " + e.Touches[0].Y.ToString() + ")");
}
private void MainWindow_TouchDown(object sender, TouchEventArgs e)
{
Debug.Print("Touch down at (" + e.Touches[0].X.ToString() + ", " + e.Touches[0].Y.ToString() + ")");
}
}
}
Error is
An unhandled exception of type ‘System.NotSupportedException’ occurred in Microsoft.SPOT.Touch.dll at
line
Touch.Initialize(this);
Attaching the touch screen images and IC details.

It also uses the MCUFriend_KBV display library. The sample code that I expect you’ve used for the display above is the DisplayStrong.ino example. The “tft” object is created as the MCUFriend_kbv object - so there’s a high likelihood you’ll need to dig in to that (but also worth noting is that driver has been written to detect different displays, so likely has much more complexity than you need, assuming you have only this display). You might try simplifying an example on Arduino to only the Adafruit libraries and see if that works, as that may be a simpler place to start from - but you’ll probably need to read the code.
