Have you coded your enum statement with a name label? Like enum week { Mon, Tue, Wed, Thu, Fri Sat, Sun} days; Right now, you aren't assigning a tag (the "week") to the enumeration. Would explain the problem with the next possible tag being main which would be illegal use. Larrie

Which compiler are you using? AVR-GCC compiles and runs your code correctly. I'll state this again just for the benefit of all those who assume they can't use GCC because it is too difficult: Studio 4 with the GCC plug in makes is brain dead simple: Just create a project, cut the

It could be, Russell, that the rest of us didn't want to get involved with this silliness. Just because a program will not compile one project doesn't mean that it won't do a passable, even an exemplary, job for most of what an individual wants to do. However, that being stated,

I haven't used DW now for a few months but my memory is that you can't program with DW and can't have both ISP and DW enabled at the same time, so the program/debug cycle isn't exactly seamless. Whereas the Jtag program/debug cycle is seriously quick and completely seamless. I fi

No, pneumatics is not a good choice, in terms of energy efficiency. probably, depending on all factors, a stepper motor with a lead screw arrangement will do the job (and you don't need four, three will do the job, and with some clever design, maybe even two actuators). There are

You can do it with motors in the way that pan and tilt is done for video cameras. Stepper motors work well but usually have to drive through a reduction system such as gears or belts. Jim On Wed, 24 Jan 2007 21:00:56 +0200 "Ümit ?en" wrote: > Thanks Leon and Tom, > One more quest
