BTW that returns time in seconds.
I wonder if its possible to access it in milliseconds (for framerate counting purposes).

You can already do it using isKeyPressed(), which supports multiple keypresses.

I added a attachment called skeleton.zip to the first post. It is the minimal part of Ndless needed to develop programs, and should be useful for people uploading source and such.

Speaking of OS2, how is it going along? Any new features planned/done ?
No, because one or two larger projects with deadlines have to take precedence. As soon as they're done, I'll get back to OS2.
How's your secret project coming along?

Your program can just detect everything on the fly; its unlikely it will use that many keys.
So, for example:
if (keypadType() == 84 && isKeyPressed(KEY_84_UP) || keypadType() == NSPIRE && isKeyPressed(KEY_NSPIRE_UP)) {
//up code here
}
Unfortunately, I do not know how to implement the function keypadType().

Hmm...you're not supposed to have '(', ')', and the like in the key names. Those should be changed into KEY_NSPIRE_LP (Left Parentheses), KEY_NSPIRE_SQU (X^2), etc.

Same as Builderboy. We have finals, trebuchets, and presentations. I'm also out of project ideas

I don't think its good style to use '+' in the key names. You should change them to just KEY_84_*.

Its just gcc, so I believe it produces slower code, but much slower.

If we had an Nspire group project, it should be something along the lines of a standardized graphics/IO/math library.
This should be followed by a BASIC-like language, either interpreted, compiled, or compiled into C source.
We need to get the basic framework for development in place before thinking about coding new games.

you are totally wrong about the way the DS it does ALL of its 3d rendering on an ARM9 clocked at 67 MHZ the N-spire is running an ARM9 clocked at 90 MHZ
from Wikipedia:
CPUs: Two ARM processors, an ARM946E-S main CPU and ARM7TDMI coprocessor at clock speeds of 67 MHz and 33 MHz respectively. The ARM946E-S CPU processes game play mechanisms and video rendering while the ARM7TDMI processes sound output, Wi-Fi support and additionally, when in Game Boy Advance mode, processes what the other processor used to do. The DS has no vector coprocessor to speak of sorry to disappoint its just got an efficient engine.
the DS and n-spire use 2 different breeds of the ARM9 the N-spire using the highest end that has special instructions for JAVA optimization and the DS uses the second to highest end that may have more cache. I'm almost positive this can be done.
as a note:I mentioned the ray caster because it showed that such things could be done. To do portal one would of course need to optimize the hell out of the current ray caster or write a rasterization rendering engine
I quote Wikipedia: The system's 3D hardware performs transform and lighting, texture-coordinate transformation, texture mapping, alpha blending, cel shading, and z-buffering
The DS definitely has 3D hardware. Good 3D graphics on the Nspire would really be pushing it. If calc84 could only get 70 FPS on an untextured, unsorted trivial scene, I doubt we can get an acceptable framerate with real scenes.

TILP is a nice program, despite its issues with the Nspire.
Another problem with the Nspire is that the platform is very new, and the development environment is a pain to set up.

Reboot your calculator to make it work (pull out a battery).
You can get gbc4nspire in the downloads section here.

You are probably suffering from some sort of power management bug.

Lets say I want a list of integers, length 6.
I'd declare it like so:
int list[6] = {1, 4, 4, 1, 7, 9}and I'd access the 2nd element with:
list[1]since arrays in C are indexed from 0.
