Ti Nspire CX

Just picked up this calculator for my math classes (embarking on a new career), as I had lost my Ti-85.

Older Thread for reference: TI and their new calculators - Education and Teaching - Arduino Forum (not exactly on my topic though)

I read that it is capable of handling inputs from various sensors. Has anyone, or does anyone know of, connected an arduino to it? I was thinking of using an arduino to parse and log data from various data (nothing in mind yet), and then sending the data to the calculator. Any info?
