(...) Assuming packets without large internal gaps, we could employ a timeout to wait for a packet transmission of unknown protocol type to end. At 2400 bps with 8E1 (LEGO, isn't it?), one data byte has 11 bits, so a space of 1.5*11/2400 s should be (...) (25 years ago, 20-Apr-99, to lugnet.robotics.rcx.legos)

(...) Excellent idea. This would yield the default settings dead-on. (...) Scaling isn't about the final output. The final output is already in the standard format. Scaling is about shifting the raw sensor values displayed by the firmware six digits (...) (25 years ago, 20-Apr-99, to lugnet.robotics.rcx.legos)

(...) Yes this will be a datagram only protocol for the time being. The LNP will allow us to do things like debugging and remote control. I have also invisioned something like a "shell" running on the legOS that you could either "telnet" in to or (...) (25 years ago, 20-Apr-99, to lugnet.robotics.rcx.legos)

(...) 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)
