Hi all, I couldn't resist the urge to do something productive after taking the exam today. Dan sent me some code offering 256 levels of power, and I hacked away at it. I played around with the assembler, and here's my new version. It adheres to the (...) (26 years ago, 24-Feb-99, to lugnet.robotics.rcx.legos)

Hi, does somebody feel up to renovating the motor driver? We have discussed a new PCM scheme earlier on the lego-robotics list, it's just a question of implementing it.

It's Doxygen. (URL) doc++ is also a viable alternative, but I've used doxygen before in Qt-based projects, where it is clearly superior. (26 years ago, 23-Feb-99, to lugnet.robotics.rcx.legos)

At least as far as CE is concerned, you need at least 8Mo to run a java VM. This is due to the size of the classes however. On the other hand there are smartcards which have an embedded VM cf: (URL) believe the VM can probably develloped but the (...) (26 years ago, 22-Feb-99, to lugnet.robotics.rcx.legos)

Small misunderstanding... The RCX firmware contains a small interpreter which runs "RCX bytecodes". These are very different from H8 machine language.

The thing to remember about legOS is that pretty much anything you can do in C (gcc, egcs) in 32k of RAM, you can do with legOS. I believe that both legOS and NQC have definite places in the RCX programming universe. I happen to have been using gcc (...) (26 years ago, 22-Feb-99, to lugnet.robotics.rcx.nqc)
