TI-Nspire TouchPad, CX and CM come with a diagnostic software which can be launched by holding down before a reboot.

The EVT1 TI-Nspire Color prototype we discovered in a previous news is no exception:

This 3.0.0.102 version was compiled on 24th september 2010, and introduces itseld as a "NSC EVT1 Version3 Diag Menu".



Development Diags softwares are usually much more interesting than production Diags softwares, as they often include additionnal options.

Let's go to the "2. LCD" menu and launch the "LCD Pixel Test":

Nothing different from production Diags are you going to say?
On a production Diags, the test would end now, yes...

But on this prototype there's an additionnal screen:

Yes, there is an image hard coded in this prototype developement Diags, which was then removed on production Diags.

For information, it's a photo from the Aspen hot air balloon festival (Colorado) and here is it:

Strangely, the photo seems to be from september 2010 too, exactly like the Diags build date. Was one of the TI-Dallas Nspire CX developpers coming back from Colorado at that time?


The diagnostics has been dumped. If you flash it on your production TI-Nspire CX, your Boot1 won't accept to run it.

But you can run it without installation using my nsNandMgr tool!

Lol, I can just say that the creation date could also be the copy date, which seems more likely
Other than that, the image is still included in the images package, so they seem to really like it

Which image package?

If you install the nspire student software, that image is placed inside the image dir from the software along with some other ones.
It's those image to make graphs on

these (if you need another clarification):

And for some reason, they have every image once for each language

seriously that's just being lazy...

@critor, can you see in what format the image is saved? Because this means some kind of format is natively supported, or am i wrong here?

It's just raw R5G6B6 top-down without a header.
That's simply the native format for the screen, which I'm using in mViewer.

oh ok, that's 1.3MB of image for 320x240 that sure is a lot of space...

Actually it takes about 151kB on calc

then i must have totally miscalculated something xp
