Weka have issued a call for papers for Embedded World 2005 (which will be held from Feb 22nd to 24th). This show has managed to draw in both exhibitors and visitors, despite the industry downturn, and the politics that surrounded its launch a couple of years ago. Although still primarily a German show, rather than a true international event, it remains the leading embedded show in Europe.
You currently have lots of time, with a September 13th deadline for the abstracts and December 15th deadline for final papers.
