I really appreciate all of the great feedback. I've figured out which way I'm going so I'll probably have more specific programming questions in the near future. Luckily for me, I've found an excellent forum for intellectual exchange. Thanks again, (...) (26 years ago, 27-Oct-99, to lugnet.robotics.rcx)

(...) That would be nice, actually. I have only one problem with stability - every once in a while, the "Run" key stops working, and all the other keys as well (don't remember exactly, but I think that's how it is).

Hi All. I'm trying to build an IR proximity sensor with LegOS, by using the on-board transmitter and light sensor. I'm having problems figuring out how to send data, however. I tried using lnp_logical_write(), but 'cu -l /dev/ttyS0' doesn't show any (...) (26 years ago, 27-Oct-99, to lugnet.robotics.rcx.legos)

(...) If ON/OFF is desired while programs run, just drop the if. If ON/OFF isn't to work while programs run, it has to be this: if(nb_tasks<=3) { killall(PRIO_HIGHEST); return 0; // killall doesn't kill self } break; What does standard firmware do? (...)
