Indeed, yeah. Damn sweet.



Here's the todo list from the README, so you can see what's still left to do:
Todo:
- Add SDL_GetTicks() for CX
- Map more keys to SDLKs
- Add support for diagonal arrow keys in events & joystick
- Should the joystick continuously fire events if an arrow key is held down?
- Put all the compiled objects in one folder, along with libSDL.a?
- Add some own function to load images stored in arrays (?)
- Add mouse supportA few of those are trivial to do, but as you can see there's not much left before a beta, if everything goes well and if I don't find any other issues.

Yes, or more generally, I fixed most of the blitting issues. Here's a short video so you can more or less see how blitting a big image runs speed-wise:

EDIT: I actually forgot to pass the surface through SDL_DisplayFormat() to convert to the screen's pixel format. With SDL_DisplayFormat() it's a lot snappier.

EDIT2: Here's another video that gives a better impression of the blitting speed (and seems like there are some issues with timers I need to fix):

While I'm dealing with the timer stuff, I decided to implement fonts. There are 4 fonts included by default, but it's easily extensible. See for yourself:



Drawing fonts is as easy as calling the SDL_NSP_DrawString() function (any TI-Nspire-specific functions I add will be prefixed with SDL_NSP_*).

Is nSDL far enough to start porting SDL programs to the nspire? Or do you need to do more work? (I know nothing about SDL, so I have no clue what you have to do to finish it) Also, could I put custom fonts off of my computer on my nspire using nSDL without having to make the font over again?

Also, the video isn't showing, maybe it's because youtube is blocked at my school? I had no problem viewing youtube videos off of omnimaga before...

I'm pretty sure the GCC we use supports floating point. Of course, it can be slow since the floating point math has to be emulated with integer instructions.

Alrighty guys, I'm happy to announce the first beta version of SDL for the TI-Nspire will come out very soon.

But before I can do that, I need someone to check one thing on their physical CX. It's everything but complicated; download the attachment, send it to your calculator and enjoy the nice fonts and just observe how the timer increases. It should output the number of milliseconds since SDL initialization, so it should increase at a rate of 1000 a second. Press any key to update that value. If it increases way too fast, just tell me. That's all I need you to do, it should take just a few seconds. Thank you a lot for whoever helps me; the faster I get the info the faster I can release SDL.

I've made quite a few changes since last update. I changed to a much faster, more flexible and cleaner font system, updated the timer stuff, fixed some issues and whatnot.

It's working very well, and the timer is very accurate!

Good to hear, seems like the problem's only on the non-CX models then (the value increases at the speed of light). Once I finish studying I'll go and beat the crap out of that timer bug, do some housekeeping and release the beta (very probably tomorrow, unless I once again end up going to bed at around 1 AM). Thanks again.

EDIT: I'll probably make some how-to thread for those new to SDL with instructions, links to tutorials and such things once something's ready.

EDIT2: Just released TI-Nspire SDL 0.1.0.

Very nice!

Need to see to test this when I installed Ndless (again) on my CX

Great job! I'll have to learn how to use SDL
