(...) Hi Matthew, it lokks like the functions are simply not defined neither in the legOS kernel nor in the libs. Following the comment in include/stdlib.h, they should be in libiberty.a, which is somewhere in the cross-compiler tree. However, (...) (25 years ago, 21-Dec-99, to lugnet.robotics.rcx.legos)

As somebody painted out today, the frequency settings for PITCH_Gm2 through PITCH_Am3 (or 23-37) are erroneous. I copied and pasted these from Martin's "Wir sind die Roboter" demo, which seems to be in error, too. A patch to alleviate the problem is (...) (25 years ago, 19-Dec-99, to lugnet.robotics.rcx.legos)

Hi Frank, (...) Did you try changing end-of-packet timing? This may be due to ringing in the receiver, or any sort of analogue issue.

Hello Martin, pthreads and select sound fairly portable. And, as I mentioned before, there's a way of having Windows dispatch asynchronous serial events to programs, so work on porting would be fairly localized. The library approach has one serious (...)
