(...) Why doesn't somebody finish up the decoding of the ROM, specifically the routine at 14c0. This routine takes the raw sensor samples and converts them to usable values, including handling the temperature and rotation sensors. The standard (...)

(...) From what little I remember about the Lego protocol, here are some thoughts. *) On reception, some Lego packets may contain data which look like the beginning of a legOS native protocol frame. Most likely, the checksum would fail (once enough (...) (25 years ago, 20-Apr-99, to lugnet.robotics.rcx.legos)

(...) What sort of safety are you referring to? Motors left running? My initial thought was of lost memory or data structures in an indeterminate state, but that would seem to be moot since you are restarting from the ROM, which will have forgotten (...)

(...) The interface is specifically datagram only. Dunno about packet reassembly; I doubt it as the philosophy is minimalism. The main advantage I see in it is the ability to change the degree of checking it does on your behalf to ensure packets (...) (25 years ago, 20-Apr-99, to lugnet.robotics.rcx.legos)

(...) I suppose we could ask for help also to non-legos owners of RCX and rotation sensors. What if any of us posts a message in the robotics newsgroup asking for some reads of rotation sensors? Raw values can be read with the sandard firmware too (...) (25 years ago, 20-Apr-99, to lugnet.robotics.rcx.legos)

(...) Exactly. I don't have rotation sensors, either. I think these values were originally gathered from Michael Nielsen's sensors. What's the current status? Is there a patch working for everybody, or do we need some calibration work? It would be (...) (25 years ago, 20-Apr-99, to lugnet.robotics.rcx.legos)

(...) rom_reset() does the trick, you'll need to #include "rom/system.h". I'm not sure wheter this is safe when multitasking. (25 years ago, 20-Apr-99, to lugnet.robotics.rcx.legos)

Thanks to Dave and Joel. I looked quickly at those sites, and there are just what I need. I am off to have a closer look now. I realized that Linux isn't required to program with LegOS, but there are other programs I am looking at using as well. (...) (25 years ago, 20-Apr-99, to lugnet.robotics.rcx.legos)
