(...) Yes, this is with the compiled classes. Trying from the source didn't work either. Could it have something to do with the CLASSPATH variable? I used the command set CLASSPATH=C:\Steve\L...\tools.jar before trying "java install" from the (...) (25 years ago, 23-May-01, to lugnet.robotics.rcx.java)

Which version did you download? I assume you got the compiled classes? If you downloaded the source, make sure all the classes are compiled, and that you are in the directory where the install class is. Andy (...) -- See my Visual Interface for (...)

Given that I'm new to Java this is probably a silly question, but when I try to install LVI I get the error: C:\Steve\Lego\lejos\lvi>java install Exception in thread "main" java.lang.NoClassDefFoundError: install Java2 and LeJOS seem to be working (...)

(...) You could use the JavaComm package, look on the Java website for it. It should not be that hard to set up the port, write to it, and then get replies back. Look at the other Java projects mentioned on (URL) to see how communication is done. I (...) (25 years ago, 23-May-01, to lugnet.robotics.rcx.java)

I (another newbie) also would like to upload data from the RCX to a Windows PC. It looks like adding the data to a StringBuffer would be a good way to save it, but I have not much of a clue about how to write (1) the Java that runs on the PC to (...)

(...) I didn't think of that, but it might explain why my attemps to use the OP cods failed (they hung the RCX completely dead). Then again, I might have used them wrong... Björn (25 years ago, 22-May-01, to lugnet.robotics.rcx.java)

(...) There still could be some special rom code that is called when the opcode is called for the standard firmware. Not very likely, but still possible. Andy -- See my Visual Interface for leJOS at (URL) (25 years ago, 22-May-01, to lugnet.robotics.rcx.java)

(...) Remember that Lejos is replacement firmware, the OP codes no longer exist as they are part of the standard firmware. Regards Gordon (25 years ago, 22-May-01, to lugnet.robotics.rcx.java)

(...) I think that the datalogging area is just a special limited firmware array, but , IIRC, since it mentions nowhere that you have to remember to keep the datalog size into account. Try using the opcodes, and see what works. Andy -- See my Visual (...) (25 years ago, 21-May-01, to lugnet.robotics.rcx.java)

(...) It does answer my question, but I was thinking that a feature like that would be more memory efficient.
