TI-Nspire / Re: Is this forum dead?

TI will keep updating the OS and try to block Ndless. From my observations, it seems like it takes a considerable amount of work to find a loophole to install Ndless, and as the amount of people here gets ever smaller, the chance of finding a loophole will decrease. If Ndless isn't available on new calculators, there will be no new members, and C++ projects (which tend to be the most fun because they get the most out of the CPU) won't be usable, so no one will visit anymore. No GBA emulators, no crafti, etc.
Development of Ndless is entirely separate and not tied to any forum, so don't worry ;)
Most new ndless applications are announced and developed on TI-Planet, whilst games can be found mostly on now.

Just transfer crafti.prg.tns, the other files are just for development.

General Calculator Help / Re: Installing boot2 on nspire CX

Is there a way to get the version in question of boot2 installed on the calculator?
No. T >= J.

If not, is there maybe a way to downgrade to a version of the software that would allow me to have this version of boot2?
You can't fix a HW incompatibility that way.

Some small news: I was able to improve mobile performance by around 30%. This will be available in the next builds or by building it from git.

I installed it on my surface pro 4 and have the tiny keyboard and calc screen like the previous person. Still usable and amazing, thanks.

You can apply the same workaround: "firebird.exe -platform windows:dpiawareness=0".

I am brand new to this site. I am a teacher looking for the TI nspire CAS emulator for my students. I have downloaded all the recommended files but I can't seem to make it work on a windows machine. Could you give me step by step instructions on what to download and what I need to install where. I need to make these instructions bullet proof for my students to follow. I do thank you in advance for my students and myself for any help you could provide.

Thank you!!!! :)

There are several pages on the wiki:
They should be able to get you started. If you have any questions, just ask :)

As a teacher you may be interested in the latest development build, which features an external LCD window that can be shown on a second monitor. There are currently no builds online, but it you want to, I can upload one.

Edit: Thanks to pimath, nightly builds for Windows are available here!

I have installed Ndless 4.0.
Is it possible to make it reboot-proof?
Nope. The installation is so simple that it barely makes a difference.

One more thing; would it be possible to remove the static from the audio? Maybe with some kind of low-pass filter?
Some part of it, yes. It only has 8 bit resolution (I tried 9 and even 10 bit, didn't work out well) so you won't get rid of the resulting inaccuracies.

Hi InvX,

"pwmtest" is written in ARM assembler and C ("the Arduino's language"), so you have to learn them to fully understand and work with pwmtest.
You have to setup your calc as usual (solder to a dock pin or connect to it in a different way) before you can try pwmtest.
There is a fairly high-level API exposed by audio.c you can use to play your synthesized tones.

File Transfer is not yet available for Android?
Not implemented. I don't have a smartphone myself, so it's been fairly low priority and it was more important to get the transfer more reliably and functional.

Keys labels with question marks here as well.
Yup, the next version is going to have them as pixmaps. That'll fix the appearance of e^x and 10^x as well.

Is there a way to add a setting to set default screen size to full keypad using the vertical size of the tablet/phone with the horizontal size not taking up the full window. This would eliminate need for scrolling keypad on larger size tablets/phones where lcd size could be shrunk without a negative affect.
Yeah, I guess a maximum keypad width in inch would do the trick. The LCD size doesn't need to be smaller, IMO, there's enough space on screen.

The "-platform windows:dpiawareness=0" works. The others are too small. See screenshot. The cmd prompts can be seen in the background.

Thanks for confirming. The next releases will probably contain a shortcut to firebird.exe with that argument added as workaround.
I also notice that on the right column of the keypad there are two keys without label. Apparently they're not part of the default font that's used on windows.
I'll have to replace them with proper pixmaps soon.

Is there anyway to have the lcd display and keyboard have size options. On the Surface Pro 3 screen of 2160 by 1440 is too small. The Asus Tab 100 screen of 1366 by 768 is just right. Even using the SPro 3 display maximum magnification is too small.

Thanks for testing! I don't have any device with HiDPI display.
It seems like Qt screwes up the scaling. Can you try starting firebird.exe from powershell/cmd.exe with "-platform windows:dpiawareness=0,1,2" and tell which option works best?
If none of that works, try to play around with the QT_DEVICE_PIXEL_RATIO environment variable, like "set QT_DEVICE_PIXEL_RATIO=2" before firebird.exe?

Existing documentation on the OS is unfortunately shoddy...  <_<
It would change for each version...

As for editing the RAM, I'm not sure where the pointer would be for the ADCs... I can get ndless to run (slightly complicated process), so I might be able to do something with that added functionality, but I'm not sure how exactly.
Yeah, you definitely need ndless.

It also begs the question: Why does a CX calculator even have code for a clickpad?
Ask TI. I have yet to see a single instruction that was removed in a version update. It gets slower and more bloated everytime.

The ADC test for channel 3 does read Fail... has exactly 1.5V, which would seem to be too high.
Yeah, it should be around 73, so ~0.25V.

How difficult would a software-based override be to code?
I don't know. Maybe it's possible to just map the 0xC4000000 region to a crafted buffer with the correct values.
Patching the OS might be easier, but would require a refresh for every new version.

Or maybe I should just jam a clickpad on this calculator somehow kek
Frankencalc... It's not as bad as combining a CX with a clickpad LCD, though :D

My question is: is there any way I can force my CX CAS to interpret its button presses as touchpad commands rather than clickpad commands? I have not taken apart the calculator yet but if there is a hardware fix I would try that.
The keypad type is indicated by ADC channel 3. Nobody knows where it is connected to on an nspire. It might be somewhere on the dock connector, if you're lucky...
Sorry that I'm not able to help much. Maybe a software-based solution is possible, hardcoding the value that is read by the OS.

Your linuxloader is too old, it does not know the dtb command.
