I'm about to write software for communicating with a NAT 9914 gpib interface. So naturally I need to parse the recieved commands with the mcu(AVR90S8515) in some way. I am currently developing in AVRfreaks gcc port (ansi c) so I wonder if someone have any good ideas of performing this parsing in an effective way? Probably someone already have done something like this!? I would appreciate all input! /niklas -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
