Adding CAS to Ti-nspire Touchpad?
« on: August 15, 2011, 07:35:39 pm »
Is it in any way possible? My first thought was simply to download the latest CAS operating system and update my calc with it, haven't tried as of yet as my computer cable has gone missingfor the moment, however I seriously doubt it's that easy otherwise everyone would be doing it. I have 2 ti-spire CAS clickpads, both of their screens got damaged, they flicker and one of the screens has gone blue. However if I hold them in the sunlight and squint I can just see the screen and they appear to be working fine, the screen just can't be read. So any way any of these calcs can be fixed so I have a working Ti-nspire CAS? Thanks in advance for any help!

There is a library somewhere called "mcas". Let me just find it for you.

EDIT: the page is in french, but here you are, http://ti.bank.free.fr/index.php?mod=archives&ac=voir&id=1884

Unfortunately, you can't install the CAS OS on a regular calc, but mcas is a good solution. Installing the CAS OS will be a possibility when we figure out how to make our own bootloader for the calc, though.

OSLauncher ftw :

To sum up : launch the CAS OS directly in RAM without installing it (Needs Ndless)

It got released? How did I not hear about that. There must not be a whole lot of free space left on it, though.

Yes it has been released.
If I have good mind, the OS takes 5MB

Thanks for the fast replies everyone. Have downloaded the OSlauncher kit and I'm already stuck on the first step. It asks me to install an older OS in order to be able to run Ndless, have downloaded and attempted to install the appropriate OS, however at the end it tells me that you cannot install an older OS. According to the tutorial this should only happen if you have a boot2 code version above 2, however mine is 1.4.1571.. Am I missing something glaringly obvious? Thank you!
Edit: In fact, having checked again the handheld status, I am in fact running 2.0.0.1.1188 version of the OS.. so installing 2.0.1.6 is in fact not a downgrade. ???

2.0.1188 is indeed not supported by Ndless, because it was soon replaced with 2.0.1.60.

Awesome thanks, fixed the problem and got it to accept 2.0.1.6 and have now installed and run Ndless and the OSlauncher. Waiting for the OS to load, keeping fingers crossed mine is not one of the 1 in 20 that it doesn't work on. Thank you!

The OS should load quickly (< 15 seconds). If it hangs, remove the batteries and retry, until it works (on my calculator, it fails maybe 19 out of 20 times...).

Be sure to either disable hibernation, or use your calculator often enough, if you don't want the Nspire reverting to non-CAS state quickly ;)

Awesome.. Yeah I waited 10 minutes, nothing happened. Reset, took batteries out, wait 10 minutes still nothing. Reread the tutorial and then tried disconnectingthe keypad as it was loading and then reconnecting it. So far, this has worked quickly for me 100% of the time for me with the very irritating side effect of the touchpad not working at all so having to do everything via keyboard shortcuts. However I'll keep trying without disconnecting the keypad and hope it works.

Edit: I kept resetting it and trying again and it eventually did the right thing! Problem solved! Thanks to everyone for their advice!

Just curious, how does OSLauncher work? Does it overwrite the copy of the original OS that is in RAM? Or does it put both OSes in ram alongside each other?
