 | | Light sensor initialization?

This should be an FAQ at this point, but I'm having trouble tracking down an answer in the LUGNET archives. I'd like my 'bot to measure ambient light levels, and make light/gray/dark decisions based on those levels. For instance, Dave Baum's line (...) (25 years ago, 13-Jul-99, to lugnet.robotics.rcx)

Dave's reply is right on the mark, but I also want to point out that if you have downloaded a non-MindStorms O.S. to the RCX (i.e. any firmware other than the standard LEGO MindStorms firmware) the remote might not work either. I haven't tried any (...) (25 years ago, 12-Jul-99, to lugnet.robotics.rcx)

Well, neither the latest release of egcs nor the latest binutils 2.9.1 seems to do it. Apparently, though, the beta binutils (2.9.4, use at your own risk, blah, blah, blah) works.
