Can't compile

[salman]

Following the manual, I tried to compile a program from the text but get compile errors. Not sure where NIGHTFONT_HANDLE is supposed to come from...the documentation is pretty vague at times on how to proceed with the examples...perhaps I need to dig into all the underlying code (GD2.h and GD2.cpp) to figure these things out.

#include <EEPROM.h>

#include <SPI.h>

#include <GD2.h>





void setup()

{

GD.begin();

}

void loop()

{



byte font = NIGHTFONT_HANDLE;

GD.cmd_text(240, 40, font, OPT_CENTER, "abcdefghijklm");

GD.cmd_text(240, 100, font, OPT_CENTER, "nopqrstuvwxyz");

GD.cmd_text(240, 160, font, OPT_CENTER, "ABCDEFGHIJKLM");

GD.cmd_text(240, 220, font, OPT_CENTER, "NOPQRSTUVWXYZ");





}

Check the top section on page 54 of the book to see what fonts are available for your use by simply giving the number.
When you try to use a "NIGTHFONT_HANDLE", you have to create that asset with the gd2asset tool out of an true type font and load it prior to use.

Change your code to:
byte font = 31;

That should work.
