(...) I have added random number generators to either of the c library, or to the float library (v0.2.3, on Linux). What I did was cd to the lib/c (say) directory, and deposit my source files there. I then edited the Makefile in this directory, and (...) (24 years ago, 28-Apr-00, to lugnet.robotics.rcx.legos)

|

Yes. I have used it successfully, though not always... In my case it seems to be a problem with the uart 16550A. It does not switch to low lattency mode correctly making the tower blind to the RCX. I circumvented the problem setting the UART type as (...) (24 years ago, 28-Apr-00, to lugnet.robotics.rcx.legos)

(...) I have given this some thought in the past, although I haven't had the (significant!) time that it would take to try this out. I think the best hope for any kind of two-way communication protocol between the PC and one or more RCXes is to use (...)

(...) Are there known conditions where lnpd works and doesn't work? Are there versions of LegOS which support it better? Mostly I wish I had at least one report of success that would suggest that there is hope at the end of my tunnel. I cannot do my (...) (24 years ago, 27-Apr-00, to lugnet.robotics.rcx.legos)

(...) I'm actually working on a small device that will connect directly to the battery posts in the RCX/Scout. It uses a relay and a few diodes to protect the RCX from reverse polarity and overload. The relay will allow you to switch from internal (...) (24 years ago, 27-Apr-00, to lugnet.robotics.rcx)

Hello Kurt, I want show you three possiblities for alternative power supplies. 1. Take 2 sets of 6 NiMH accus or 2 * 6 NiCd accus to have one set inside the rcx an one set in the charger. This would be a very simple way to solve your problem. 2. The (...) (24 years ago, 27-Apr-00, to lugnet.robotics.rcx)

My thinking is that if you send junk and trample something, so be it; the tower would have gone dead anyways, forcing you to lose whatever it (...)
