(...) I'd say this is the way to leave it, since it seems to be how you meant it in the first place. It's just very annoying to take out the batteries if ON/OFF is pressed by mistake while something is running. (...) Don't know, I've never used (...)

Hey, this is a small but frustrating one. This is in legOS 1.7 but I beleive it will still be in 2.0 as it's caused by the 1 priority to a task requirement. If you write code like the following: while(1){ wait(for something); kill(t1); t1 = (...) (25 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? (...)

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 (...) (25 years ago, 27-Oct-99, to lugnet.robotics.rcx.legos)

(...) 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).

(...) Count me in. I'm ditching the Tcl interface - it's just too damn goofy! A standard firmware downloader would be great - especially if it ran on all platforms.

Hi, yes, currently, you'll have to make main() your first function. version 0.2.1 will support arbitrary starting offsets. could you report about the stability of repeated program runs? if this works fine, I'll change the ON/OFF behaviour to (...)
