(...) I have not done any experimenting with Data Streams yet since I can get by with bytes. I have tried both the RCXPort and the RCXF7Port. The big advantage of the RCXPort using the LLC protocol is that if the RCX gets out of range or behind an (...) (24 years ago, 13-Sep-02, to lugnet.robotics.rcx.java)

Hi Kaspar, Did you compile the PC end program using javac and did you add pcrcxcomm.jar from the lejos lib directory to your CLASSPATH? Could you give some more details about your problem (what platform are you working on? complete code...)? Wap (...) (24 years ago, 12-Sep-02, to lugnet.robotics.rcx.java)

Ok, here's a little something to think about: I have been testing the three communication protocol stacks of LeJOS 2.0 (josx.rcxcomm package; LLC, LNP and F7 protocols). Simple application: Array (size 20) of ints on both PC and RCX. Got both a (...) (24 years ago, 10-Sep-02, to lugnet.robotics.rcx.java)

(...) That's currently done in the leJOS loader (see rcx_impl/main.c), and only if no program is running. So you can't turn it off, but you don't need to turn it off either once your program is running ... Jürgen (24 years ago, 5-Sep-02, to lugnet.robotics.rcx.java)

What about turning the timer off that turns the RCX power off. What would be the class and method or is it a ROM routine. Thanks, Scott (24 years ago, 4-Sep-02, to lugnet.robotics.rcx.java)

(...) Interesting, I should browse through the classes every now and then ... One thing to note is that josx.platform.rcx is not the right place for it, as it is independent of the RCX platform (maybe josx.util ?). (...) I think it would be better (...)

(...) If you already know some Java, I recommend Lejos. It has some very reliable classes for RCX to RCX communications using Java streams. It also has some useful debugging features. Good luck, Roger (24 years ago, 3-Sep-02, to lugnet.robotics.rcx.java, lugnet.robotics.rcx.legos)

Hi Scott, (...) yes. It is like a big wall clock that shows milliseconds. (...) System.currentTimeMillis(); Note that this is a long integer.

I am using legjos and... having problems understanding the clock/timers. 1. Are their only one timer clock? 2. How do you acess the timers clock? What code would I use? Scott (24 years ago, 29-Aug-02, to lugnet.robotics.rcx.java)
