Hi Chris,

Do a search for "CM-RCX Comm" thread, in lugnet.robotics :)

That's (still) my main current project.

It works. It's possible to make a CM and a RCX communicate with each other
through "eletric" (or light but I didn't test the input through light, yet)
connection.

I was working on a custom version of the standard LEGO VLL serial comms
protocol. My "SlowVLL" is 9 times slower than standard VLL, but the main
thing is: it works.
I created SlowVLL protocol because the CyberMaster doesn't support
FastTimer(), (RCX2 firmware does), so, for now, it's impossible to do input
on a CyberMaster at a standard VLL data rate (but Standard VLL output to
RCX2/MicroScout/CodePilot is possible).

After doing some tests on "SlowVLL" input, I was going to finish my lib with
both SlowVLL input/output and Standard VLL input(RCX2)/output, *BUT* I
encountered a problem with memory capacity on the CyberMaster :( ...for now,
the current (complete) version of my NQC lib needs more memory than
CyberMAster has to offer.

On top of that, my spare (hobby) time is equal to zero :(

I'll post future info on lugnet.robotics under the "CM-RCX Comm" thread :)

mc.

PS: OH! I just got the #9754 Dark Side Developer Kit set, so now I'll have a
MicroScout to do some Standard VLL tests and calibration of my lib's output
routines :)
By the way, the 4 legged walker WALKS PERFECTLY ! Great LEGO design job.
...now, I'll just have to think a way to make it turn :>

Subject: RCX & Cybermaster


Has anyone tried (successfully, or not...) to create working
models or systems using both of these items together?

I'm guessing that I could use a mechanical feedback circuit
(like 8868 alt. model / 8479) to trigger the RCX from the
actions of the Cybermaster, and vice-versa, but I haven't had
the chance to try it yet. Is there any good way of making
them interact electronically? (other than just linking the
same touch sensor to inputs on both to trigger different actions, say)

Thx,
Chris.


Thx, Marco. I'm investigating! btw, Do you mean that they communicate
through a standard lead attached to sensor inputs, say, or some other
electrical connection? Interesting that the CM can't communicate at speed,
but the MS & CP will. I'd noticed the lack of memory in the CM also - it
doesn't hold a very long period of recorded motion.

Unfortunately, I'm suffering from that lack of hobby time also :^(
but I'm probably also trying to bite off more than I can yet chew on this one!

Chris.
