Doing too much with the TI-Nspire dock connectors?
« on: August 13, 2011, 02:48:00 pm »
In the past few months, the TI community members accomplished various things via the TI-Nspire dock connector located at the bottom of the calculators. After breaking anti-downgrade protections, unbricking calculators hit with the Boot 3.0 glitch in OS 3.0.1 and controlling external perhipherals through it, Jimbauwens managed to get sound on his calculator in Lua. A video is available here.

However, recently, Adriweb paid a visit to TI in Dallas. He got to see various things such as the new TI-Nspire CM that was discussed about recently. What was discovered is that this connector is no longer present on the new model. Only a mini-USB jack is now present on the side.

Is it simply a random hardware change or did TI try to prevent us from doing too much with the dock connector?

How will they get the lab station and wifi cradle to work now?

I think they are just making a budget calculator. Many students don't need a lab station and/or a Wifi Cradle.
But yeah, the downgrading might have helped it.

Yeah, sounds more "removing stuff to make a budget calc" than "removing stuff to piss off the community". Hope they set the price accordingly so people would buy a CM if they don't need all the features of the CX.

I don't really see how that saves money, though. The dock connector contacts were just printed right on the circuit board anyways.

I think they're ready for anything to prevent us from doing too much, even if that puts them bankrupt. :P (well maybe not this bad but...)

I don't think they are set against us, just that they are worried about losing stuff like test certification if we can make these calcs less secure.

So, priced as if it were made out of solid Gold instead of solid Platinum?

wow this is amazing and the code is very simple, you can create any monophonic song knowing the notes and changing the list happy_birthday but where I can get the codes of the notes?
I gathered some using this file but there must be a complete list, Jimbauwens could you specify the notes and codes please?

I actually use frequencies in this program.
There are some programs available to the conversion.
Or if you know the notes you can use this list: http://www.phy.mtu.edu/~suits/notefreqs.html to do the conversion manually.

Would it be possible to do more complex sounds? Nyan cat is possible on an 84, it should be possible on an nspire...

Well, I guess you can do more complex stuff, but the quality will be better on the 84 because you have more control over the output.
And with the latest update you can't have any sound anyway :p
