Hey, I am trying to interface with the TI-83+ Calculator though the Link port which uses a DBUS. I built this Circuit here http://zastava.student.utwente.nl/linkguide/hardware.html. Where it says input, that is the Arduino read line, where it says output, that is the Arduino write line. I built it twice, once for each wire.
Does anyone here have any ideas on how to read the packets from it. The guy here http://arduino.cc/forum/index.php/topic,19413.0.html did it, and posted his code, but his site doesn't exist anymore and can't get his code. And for anyone wanting to know the packet information it is here http://zastava.student.utwente.nl/linkguide/
