I've just released a new version of BricxCC. This release add support for downloading non-standard firmwares (such as pbForth). I've also added support for several languages other than NQC with user customizable syntax highlighting. These languages (...) (23 years ago, 7-Mar-02, to lugnet.robotics.rcx)

when i first got legOS up and running i used rcx-egcs-1.1.2-1.i386 rcx-egcs-c++-1.1.2-1.i386 rcx-binutils-2.9.5.0.22-1.i386 i'm assuming the first two are the c and c++ compilers, however what is the function of the binutils? thanks (23 years ago, 7-Mar-02, to lugnet.robotics.rcx.legos)

Hi, I have a couple of RCX's and was wondering if anyone has done any work on a way to transfer a program from one rcx to another in the case of a battery failure, etc. instead of replacing the rcx in the robot with the other one. thanks (23 years ago, 7-Mar-02, to lugnet.robotics.rcx.legos)

i tried the lejos environment and found the exponent and trig functions worked very well. and they work with doubles. so if anyone is having trouble with using trig, log, exp functions in legOS, you might want to try lejos. plus it was easier to (...)

(...) The firmware downloader built into BricxCC is a port of Dave Baum's NQC code to Delphi. It calculates the checksum up to a length of 0x4C00. The limit of 0xCC00 is based on the sum of length + start (where start is = 0x800). John Hansen (23 years ago, 6-Mar-02, to lugnet.robotics.rcx.pbforth)

Experimenting with Lejos, two 'major' problems: memory (cleaning up platform & lang: Math.class is huge!) and... threads.
