Hey all.. This may be a simple question, but is there a way to print text (using consolePrintf()) to the second screen?
Also, how do I print an integer using consolePrintf(), or should I use a different function? Thanks for any help.

Don't know the answer to your first question, but to print an int with printf, do something like this:
| Code: |
int i;
consolePrintf("The value is i is %d",i);
|
and it will put the value of i where the %d is. YOu can also do this with more that one variable, like so:
| Code: |
int i;
int j;
consolePrintf("The value is i is %d and j is %d", i, j);
|
and it will put the variables into the %d markers in the order they are listed

Yay, thanks very much.. I'd tried using %d but I'd forgotten the integer name had to go after a comma... D'oh.. For the while I was using consolePutInt() which wasn't fun, trying to guess X and Y values.. But now I don't have to, thanks for your help..

In the example programs (eg hello world) near the start of the arm9 main function you'll notice some functions are called - can't remember the names exactly but along the lines of SetMode and SetBank - involving BG0. there are *Sub versions of some of the functions, and SUB_ versions of some of the definitions - I'd suggest looking up all the calls that look like video initialisation in ndslib/include/NDS/arm9/video.h - thats how I figured out how to do it :) I'd give you some code if I were at home, but I'm at work at the moment so I don't have access to it.
Hope that helps!

Currently you can not print to both screens at the same time as there is only state variables (cursor position and that sort of thing) for one screen at a time. You can however print to either sub or main display and any background layer as long as you specify the correct color depth to the init function.
