  Re: Electrical Data Link between 2 RCXs
 
Hi Bernd, When you need it really fast, you sholud use legOS instead of NQC. A program written with NQC uses the LEGO firmware, which is a ByteCode Interpreter. This pogram is interpreted Byte after Byte from firmaware. The firmware executes the (...) (24 years ago, 26-Mar-01, to lugnet.robotics.rcx.nqc)

  IR communications related questions
 
I've been working with LegOS for a while but am quite frustrated. I have been unable to get lnp working and am thus unable to to communicate with the host. It is all overkill for me since I merely want to capture some simple data. I am switching (...) (24 years ago, 1-May-00, to lugnet.robotics.rcx.pbforth)

I am coming into the middle of this (or at the end considering the posting dates), and am hoping I don't sound like a fool putting out these ideas (since I don't yet know how legOS works). Is the RCX# used as a sort of ethernet MAC address? If you (...) (25 years ago, 28-Jul-99, to lugnet.robotics.rcx.legos)

  Re: Interactive communication with the RCX
