[SOLVED] total newbie problems

[Montiey]

Thats very weird..

[Montiey]

I'm going to start chopping things off until it works, so I can see what killed it.

To answer your other questions, while 1 is the same as while true. And your program isn't using too much memory (looks like it's using 800 out of 2000 bytes, most of which is used up by the gamebuino library)

[Montiey]

I even chopped it down to this and it still doesn't work:

Code: Select all

//imports the SPI library (needed to communicate with Gamebuino's screen)
#include <SPI.h>
//imports the Gamebuino library
#include <Gamebuino.h>
//creates a Gamebuino object named gb
Gamebuino gb;

After I load the game, the backlight cuts off while it is finishing loading (Loading text still visible), and then the screen clears and stays blank.
Maybe there is a problem with my libraries or the way the gb.begin and # include functions are working, because the backlight is never activated?

Eventually I figured out my problems with some "help" from Myndale.

All the problems in this thread have been solved.
