Hi, just wondering if anybody has any experience interfacing their TI calc to a pic. Seems like quite an interesting thing to do for data collection etc.. Unfortunately I can`t find any really good info, sample code etc. Any ideas??? BTW on a different topic, just came into my head if you are making a robot why not track it by using the guts of one of those new microsoft mouses with intelieye. Just a thought. ________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com
