TI-Nspire / Re: nleash and oslauncher still not working!

You don't need a CAS on the SAT if you are proficient in basic mathematics. Any little four-function calculator would do the job just fine.
GB FTW!

following some search that I've just done it looks that rs232 is the protocol and ttl a standard and in fact we will be using both here: http://answers.yahoo.com/question/index?qid=20090211134205AApzAvY

following this we will be using the rs232 protocol with the ttl voltage levels.
and it looks very common to be like this...

EDIT: Aborting this idea since the baud rate of the nspire is 115200 it's too high to a picaxe microcontroller. I don't know if the nspire's baud rate can be lowered or it the arduino supports such a high baud rate.
Anyone here knows?

I'm not sure if it can be done with single bytes since I don't know exactly how the RS232 protocol works, but I'm sure it won't be that hard to accomplish some communication between both and to exchange strings of data.

To start I'll want to show data read from the temperature sensor on the calculator screen.

These are the topics in question on the nspire side:

there are commands to send/recieve strings (through serial RS232) on both the picaxe and ndless ;) so it should be fine.

I'm near zero in C programming also. We would start at the same level... I think that the harder part would be the C programming to the nspire since the electronics part and the picaxe programming seem pretty easy ;)

I'm also taking my 1st steps through the world of electronics and what I did was to buy a 28X1 picaxe microcontroler which is programable in BASIC and it's really easy to start with. Then I bought a breadboard, a capacitor and a resistor kit, a bunch of LEDs, some temperature sensors to have some inputs, some ICs and so on... I buy most of that stuff in ebay, except for the PICAXE microcontroler.
You can also buy a project board with the microcontroler... I think that it is easier to program than the arduino but to some extent is more limited also so I am planning to buy an arduino in the near future even knowing that by now it can do anything I imagine doing to do.

I am planning to create a shield to interface with the nspire through RS232 and a C program on the nspire it would be great to have some help thinking about that :D

this is great! but... when will this be implemented in the grayscale version?

69
are there any libraries to communicate with external devices?

like something to send/recieve signals through the same pins as we connect RS232.
that way we could make the calculator interface with anything through an arduino or picaxe...

I'm taking a wild guess here but, the first "Rocket"?

We are getting ready for 8 colorful rockets, stay tuned…
No.
so this isn't one of the rockets?

how would you charge it :P ?
Through USB.
Just like a regular nspire battery

this is great and you could also add a button to export to tns using luna...

critor, just wondering... did you already installed OS 3.1.0 on it?

I think that the next thing you should add to the AI is a way to check if there are any moves to take over opponents pieces and if there are various moves possible for that to choose the moves for taking the most pieces.

Thinking on me and all the others that have non-CX nspires I think that you should really test all the colours to check if they are easily distinguishable in grayscale.
