Absolutely.  What I have in mind is that the basic level of access is to
the raw sensor value of the A/D converter and whether it is active or
passive.  The interpretation of that value would be done by other classes.
For example, I would like to have a TouchSensor class that works just fine
using the standard Lego sensor on an input port all to itself.  I would like
to have a MultiplexedTouchSensor that interprets values from an input that
has multiple switches attached to it.  The interface would be the same so
you could pass an instance of MultiplexedTouchSensor to some code that
expects a TouchSensor and it doesn't know the difference.

If a sensor required something different than a basic passive or active
sensor, there would have to be native code to accomodate that.

Sorry to return to this, but any is going to provide some connection to
the PC with some library, or even remote debugging capabilities?

One of the reasons for choosing JVM is the development environments already
available for every platform.  For debugging, you simply load the classes
which emulate the RCX's hardware and everything else is already there.

As for communication between the PC and the RCX, that is a network protocol
issue that is beyond the scope of the initial project but could easily be
added later.

(...) Not that I disagree with the elegance of being able to define a class that implements a new way of reading a sensor; however, I thought I'd point out two issues you might want to consider: First, the ROM already contains a significant amount (...) (25 years ago, 6-May-99, to lugnet.robotics)
