This topic is the new home for nspire_emu, the TI-Nspire emulator with the highly uncreative name.

Current version: v0.70 (post, download)

So is there a download here? (and yeah, that can be a little troublesome)
Logged


Grammer Download (2.29.04.12)
Latest update (possibly incomplete)
My pastebin
Spoiler for FileSyst:
FileSyst is an application that provides a folder and filesystem for the TI-83+/84+ calculators. It is designed to be easy to access and use in BASIC, and it can be used to access game files and save data, or to create a command prompt, among other things:

Spoiler for Graphiti:
This is a graph explorer for graph theory. It will require lots of work to finish. Currently you can:
Add/delete vertices
Add edges (direction not shown, but they are directed)
Arrange vertices in a circle (in the future, you will be able to define levels of rings and the number of nodes in each)
Create complete graphs quickly

Plans:
Add adjacency matrix viewer
Deleting edges
Multiple graphs support
Arrows for directed graphs
Planarity testing
Matrix operations
Weighted edges
Chromatic polynomials
Chromatic numbers

Yay for that. Will there be another linux-compatible release? Smiley

Perhaps. The CX isn't just a normal Nspire with a color screen. We know it has extra RAM and flash - what else in the hardware might have changed? We'll just have to wait and see.

Someone else made that, not me. I'm not familiar with Linux GUI libraries.

Anyway, here's the new version, 0.50:
  • Implement enough USB emulation to get file sending to work. This is a big milestone: No more OS-version-dependent code! Cheesy Yes, that's right, you can now send documents to any OS version, past, present, and (hopefully) future.
  • After an error, debugger command "c" now resets rather than quitting.

I should probably update. I still run 0.20. X.x

Btw glad it's not available for download for more people and I'm glad this is still in the works. Are you still planning to post updates on UTI as well too? You could probably just link to the Omnimaga attachments since they aren't that big.

Will this version run at accurate speed?

nspire_emu works well on Wine, which lessens the urgency of having a native *nix version.

Great changes, as usual Wink

This is good to hear. Most programs work in Wine, but there are exceptions, such as Starcraft Battle.net and RPG Maker VX database editing section.

Excellent Goplat, as usual!
Does this mean that we now have enough information on the USB controller to implement on-calc drivers?

Timing is the same as it always was (1 instruction per cycle). I may make it more accurate at some point, but various features of the CPU make exact cycle timing impractical.

I think we already did: we know that it's Freescale's USB OTG module, revision 0x42; you can find documentation of it in the MCF54455 reference manual (the MCF54455 is not related to the TI-Nspire but just happens to use the same revision of this module). The host interface is based on EHCI 1.0.

I'm wondering how quickly support for OS 3.0 will be added.

I have just experienced a bug, after idling around in the nspire home screen for some minutes, the console starts spamming usb resets and I can't send any files... I have used 0.41 before and haven't had this error.

This is actually not new, there have always been problems when the OS tries to go into standby (after 3 minutes of idleness). In previous versions, you would see an infinite loop of unsupported USB port accesses:

That's not what I mean, I have set the standby time to 30 minutes  Wink

My output looks more like
Code: Select All | Copy To Clipboard

1
2
3
4
usb reset
usb reset
usb reset
...

And the calculator doesn't crash.

EDIT: usb reset, not cpu reset..

Yes. With the new modifications to the USB code, the symptoms have changed, but it's still the same bug. And I still don't see it any sooner than whatever the standby time is set to (unless emulation is sped up by pressing "`" or something)
