I've been very busy lately but still wanted to do something calc and programming related, so I made this:

It's a bit hard to see, but it's snow falling down (I should have made a .gif...)

Uses the native OS thread functions, so if it crashes, it's the OS
Only works on CX CAS 3.6, haven't included the syscall addresses for other versions.
To get rid of it, turn it off and on again, although it will leak memory if you do that. It's not in any way a clean implementation, but who cares..

Yup, although it's believed on cemetech that I'm French...

Hey Guys,

I added to this to work on a few more calculators by plugging in some values from here: https://github.com/ndless-nspire/Ndless/tree/master/ndless/src/tools/MakeSyscalls/idc .  I only tested with the CX CAS 3.1 and CX non-CAS 3.6 so this may be incomplete.  But I included my small source update and so if it doesn't work for you I hope it will be easy to continue where I left off.

Well thanks for taking a look!

I wanted to try it using 4.5.0 value (0X103B18D4), but I have errors at compilation time.

I'm using Ndless v4.5 r2013 for TI-Nspire OS v4.5.0.1180

The goal is to understand how I can do some kind of multithreading.

It’s because these examples are using the old screen api (now depreceated)
