I can't build my own legOS kernel, but I can build .lx files and load them with dll without any problem! It's really liberating to have REAL functions and a REAL C implementation to work with. Right now I'm working on a bot which tries to stay on a (...) (25 years ago, 11-Jan-00, to lugnet.robotics.rcx.legos)

(...) I am seeing exactly the same thing when I built my own legOS.srec from scratch. The kernel seems to run fine (view, on/off, prgm, run buttons) until dll crashes it. (...) Auugh, I too am using gcc-2.95.2. If I use legOS.srec/.lds from the (...) (25 years ago, 11-Jan-00, to lugnet.robotics.rcx.legos)

(...) IMHO, spirit.ocx doesn't provide OO capability - it does serve as an enabler, though. What it provides is the ability to write a VB program that writes an RCX program. This VB program can be as OO as you want it, but the calls to spirit.ocx (...) (25 years ago, 11-Jan-00, to lugnet.robotics.rcx, lugnet.robotics)

What I mean is to think the RCX in OO. For example, I can add a sensor object in my programming code when I plug a sensor into my RCX. I can make the sensor object to interface with the RCX object in the OO manner. Is that possible? I learned some (...) (25 years ago, 11-Jan-00, to lugnet.robotics.rcx)

The standard RCX firmware with its serial protocol could not talk to a GPS, but LegOS could. With LegOS and a GPS we could make robots that could tell where they were. This would be way cool.

Hi Tobias, If you're a computer programmer, I'd definitly suggest using something other than the RCX Code method of writing programs for the RCX. NQC is a nice environment if you know C. If you know a language that supports ActiveX, you can program (...) (25 years ago, 10-Jan-00, to lugnet.robotics.rcx, lugnet.robotics)

Hi Mathew, There are no objects on the RCX, in the sense that there are no vtables on the RCX. I made no changes to spirit.ocx. But I definitely think of the RCX code in terms of objects now. There are "brain" objects, "map" objects, "identity" (...) (25 years ago, 10-Jan-00, to lugnet.robotics.rcx)
