the lcd module version 0.1.1 from the example directory i get the followings 
messagges:

-At the moment when is loaded the module:
Gtk-CRITICAL **: file gtkwidget.c: line 3824 (gtk_widget_set_events): 
assertion
`!GTK_WIDGET_REALIZED (widget)' failed.

NOT SUPPORTED

Hmm. I see that too. I'll look into that.

The LCD module does not support every single feature of the LCD. In this
case, gpsim is telling you that two commands were recognized, but are not
supported. A third command was not even recognized.



Now, even though the gtk error is displayed, the LCD module does run
correctly.  I suggest trying out the example software that is in the
lcd-0.1.1/examples subdirectory.

Invoke the example like this:

gpsim -c lcd_mod.stc

That will start gpsim, load the example, load the lcd, hook everything up,
etc. Then when you run it you should see the message "GPSIM WROTE THIS"
printed on the display.

If the example works, then either your software is using a feature that is
not supprted by the gpsim LCD Module or there is a bug in your code. If
it's the former and prevents your code from working, then please let me
know and I'll try to fix it.

Also, I'll look into the problems with gtk... (BTW, there is a graphical
bug in the LCD module. For some reason all of gpsim's windows get painted
with an LCD green background when the LCD module is loaded. I think I know
why.)

Regards,
Scott

Thanks Scott,

That's right, the example works fine, the error messages about the 
unsupported commands still appears when i the run the example, but is working 
well.

I'll check my code, i suppose i mismatch something because my code is working 
fine with a real display from POWERTIP and i think it may work with gpsim.

Another question, it's possible to attach a node directly to VDD or VSS (1's 
or 0's) without use a specifically pin?  

Thank you again, Scott for your time and for your excellent work.
