(...) Hi Jonathan, I send messages from the PC to 3 RCX's with no problem, but I use the Tower object running on my PC, and Serial in the RCX. I don't use Stream objects because they actually only send one byte at a time and not yet very reliable. (...) (24 years ago, 7-Jul-02, to lugnet.robotics.rcx.java)

I'm working on a project that requires four RCX's to be controlled by one laptop. The program on the laptop is written in Java and the program on the RCXs is written in lejos. I'm using RCXPort to establish a connection between them. The problem I'm (...) (24 years ago, 7-Jul-02, to lugnet.robotics.rcx.java)

| | MinuteTimer and currentTimeMillis()
|
|
I am writing a class which can be set with the actual time and then provide the value to other classes. It only has to be accurate to the minute. I've done this in NQC, but am trying to figure out how to do it using Lejos. If currentTimeMillis() is (...) (24 years ago, 15-Jun-02, to lugnet.robotics.rcx.java)

Your best bet for replacement firmware is leJOS ((URL) If you don't currently know Java you could try out my book, "Core Lego Mindstorms". It has a 30 page chapter that introduces Java programming concepts. - Brian (...) (24 years ago, 8-Jun-02, to lugnet.robotics.rcx.java)

(...) Yes, you are both right (Thanks anyway) 1. TextLCD.print() works perfectly when called from simple programs 2.
