Arduino Compatibility

Hey- first of all sorry for double posting but I think I posted this in the wrong section before cause no one replied. Anyway I was wondering if it would be possible to controll the Arduino with a TI Graphing Calculator, and specifically the TI89 Titanium because it has a USB port built right in. I know it seems redundant to plug a calculator into this board and run code off of it, on something that is fully capable of being independant, but its for a robot and since the Arduino lacks an LCD screen, I thought it would be neat to use a TI calculator with it ( almost every single person that went through high school in that past decade has one) to output sensor info and use the extra memory for differnt programs if your caught somewhere you dont have a computer to quickly change a program (quite common in robotics since things tend to need tweaking ever so often). Anyway, just let me know your thoughts on that and if it is possible, how would be nice as well. Thanks in advance- Brandon

hi

afaik the answer would be no, as the Arduino's USB chip requires you to install USB drivers on the side that is talking to the chip. I'm no USB guru but I also think it would not work because because they are both 'slaves'
