I should preface this with saying that I'm an Arduino and electronics newbie, but I'm good with computers and quite happy to learn as I go along. I tend to start with a project idea and learn what I need to do it. So: I'm thinking of trying to interface an Arduino with my TI83+ graphing calculator.…

Yup, you've got yourself a "logic level" serial port which is compatible with the logic levels of an Arduino. You can use a SoftwareSerial class to connect to the TI83+ at "moderate" speeds, or use an Arduino with a second hardware serial port like the Mega (or our Rugged Circuits Gator board which …

Okay, cool. There's some documentation out there already on the file formats. If I learn enough asm I can just make my own protocol, or use TIBASIC. I just need to work out the call and response needed to send a single variable, for starters.

EDIT: nvm, I think it's working. Couple of errors, and bytes seem to be being subtracted from 255 when they show up on the calculator. But it does work! Okay, I'm not doing very well. I'm just getting "255" when I use an asm routine (triggered in TI83 BASIC) to read from the Arduino. When I use New…
