TI-Nspire OS 4.2 released

[Adriweb]

Probably, but for now it's not updated yet.

Thanks for the two links Adriweb

The guidebook is giving some examples to use the new send/get commands, with a mysterious USB interface device for now :



- read the state of a green LED :

Code Select Expand

Send "READ GREEN 1"
Get green1
or

Code Select Expand

Get "READ GREEN 1", green1



- Turn on a green LED for 0.5sec before turning it off :

Code Select Expand

Send "SET GREEN 1 ON"
Wait 0.5
Send "SET GREEN 1 OFF"



So the new device seems to be something relatively complex, as being able to understand some kind of a script language.

Can they be used to send files between two calculators?

[critor]

I don't. We would first need to discover what's the new USB device by TI.

For example, here's the never heard of TI-Nspire DataTracker cradle which has just been discovered and adds 3 USB ports to the TI-Nspire :

Well, this sucks... it sounds like the new  commands would be cool for Basic programmers, not that really anyone uses Nspire BASIC

Who said it didn't work in Lua ?

Would anyone actually buy this though? Cause it seems really obscure and expensive.

[GalacticPirate]

Actually this is old and discontinued

Darn that looks pretty cool. Inb4 they release a ps3 controller adapter

Nspire-Lua API 4.2 Documentation/Guidebook

The ASI ("Asynchronous Serial Interface") things are more exciting than I thought - it looks like it allows to talk to any serial device correctly communicating with the Nspire/computer

So yeah, any board, Arduino etc. will work.

Woohoo ! Thanks TI for listening

On an off-topic note, contrats @critor for the ticalc.org news position.  I think the community will benefit a lot from this, since you know so much about new calculators and releases

Also nice discovery Adriweb . I wonder if this means that the Nspire CX is now more open? (even if not Ndlessable yet)

[Lionel Debroux]

We'll see what their serial device interface is precisely. There's a standard USB class which can be used for serial communications (CDC), but the usual USB serial chips (FTDI-232, CP210x, PL2303, etc.) use vendor-specific class.

[semiprocoder]

Are there any pictures of it being connected to an arduino?
How would you hook it up and are there any pinouts for the serial port to show which pins can be used for serial and which ones shouldnt be touched?
Noob questions and I know they havent been answered yet, but when an answer comes that would be great.

[Adriweb]

Regarding the new OS 4.2 Nspire-Lua APIs mentioned in the updated documentation, mainly the ASI (Asynchronous Serial Interface), I've hooked up an Arduino Uno to my computer and quickly wrote a script on TINCS using those APIs to interact with it a bit, and anyway, it works:





Jim Bauwens' tests show that the handheld isn't as happy, though (but doesn't blatantly say that the plugged in peripheral isn't compatible either, as it's been the cases before...), so we'll know more about compatibility during the T3 conference...
