Being able to control our computer, especially an emulator, with a calculator would be nice. I just hope that the TI-84+ doesn't get discontinued, because it would suck if no calculator that is still in production was supported. But I understand the difficulty of implementing USB support >.<

I does already exist in fact : https://www.omnimaga.org/the-axe-parser-project/usbpad8x-usb-keyboard-axiom/
You can control your computer with an axe program :p

I guess we should first focus on getting it up an runnign on a 84+  :)
MAYBE we could try adding some more models later, we'll se ^^
@DarkestEx: Using the SD memory trick, do you think we could later add compatibility in an update? Or would entirely new hardware be required?  :ninja:
It's simply not possible.

Oh right true, what was I thinking lol?

In any case, for a larger audience the WalrusLink needs to not require way too much hardware modding, especially soldering, for the user once it's  completed, since some people tend to be scared of soldering or suck at it. Something cool about the Nspire connector that some community member did years ago was that it could be plugged into the Nspire dock port without opening the calc case.

we got a buit-in SD card on which teh entire software is saved. So whenever we decide to update something you dont need to buy a new WalrusLink, just take out teh sd card and replace the old files ;)

Yeah I meant to implement the WalrusLink in the calc in the first place. :P That said, not having to buy a new one every time already helps :)

Hi :)

Just got a PS/2 keyboard working on a TI-83. It was kinda easy, since there are already libraries for PS/2 input and TICL.
I thoug: the old an unused Scroll Lock can be used to switch between normal and tokenized input. NumLock can be used to enable a special input for asm programs.

I think the best solution for the hardware that requires few soldering skills is this:

All I had to do was solder 4 jumper wires. It can be easily connected and disconnected to the Arduino. The same for the stereo jack.

Heya Mario AR and welcome here. :)

I wonder if PS/2 keyboards and mice are still widely available for sale? IIRC Staples charge $70 for an USB-PS/2 adapter

Implement the ESP8266 interface that'd add WiFi!
Now would that be even more great with crude on-calc web browsers and stuff?

Forgot to mention, I used an USB keyboard, with an adapter.
$70 for an adapter? Thats insane! I got mine for less than $1.

Most cheap USB keyboards work with these.

What would be really cool is streaming your PC screen to your calc O.o

that should be possible, but mind that the entire downscaling would have to be done on the PC's side since the calc would lack the processing power. So we'd end up with a blurred image whene u could see almost nothing of any GUIs and stuff, abd it would be a mere slave, non-functional without the right software on the computer (just like that good old irc program for the 83+)
