I've been meaning to make a web page about a recent experiement of mine.
I never get around to it so I figure I ought to just post it now. I was
wondering if one could use VBScript to program an RCX via spirit.ocx.
So I tried it. And it works great. Windows Script Host (WSH) can
interface with spirit.ocx just fine.
So if you are interested in programming the RCX using Spirit.ocx then
WSH provides a free way to do so. Any WSH langauage should work with it
just fine (VBScript & JavaScript are built in already). Other languages
have WSH plugins which are available from 3rd parties (for example I
believe there is a Perl version for WSH).
One interesting thing I think this should make easy is to make calls to
spirit.ocx inside a web page, or on a web server. Seems like it would
be an interesting way to write a custom remote control for a given
robotic design. Or allow people to remote control (or program) your RCX
via a browser and your web server. I'm sure other people have probably
done this already, so I doubt this is anything new.
You can get the lastest version of WSH from
http://www.microsoft.com/scripting WinXP has the latest version in it.
Win2k has a slightly older version (which shouldn't matter for spirit
programming). I think all other versions of Windows need the download
installed.
In VBScript one creates the an instance of the spirit object like this.
Set oSpirit = CreateObject("Spirit.SpiritCtrl.1")
One can then use the SDK docs from Lego to do stuff.
Attached is a VBS file that I used to experiment with. It should be
enough to get anyone started.
Enjoy

Thanks for everybody's help. It does appear that I was using an older
version of RCXCC or NQC. Also, the firmware of the Vision Command was
precisely what I needed.
Now I only need to find a free Visual Basic compiler if such a thing
exists.
Build well,
