  simple beep
 
Is there a clear way to just create a brief beep or tone in legOS-0.1.7? I've never really looked through the direct-sound code, and one of my fellow students wants an answer NOW- so I thought I'd ask here before digging into the code. Anyone? (...)

  Want rover.lx compiled on linux
 
Hi, i'm trying to track down the problems i have to download rover.lx to my rcx on Win95 (i get 'unable to load legOS executable from rover.lx'). So i have a little request: i would like a copy of rover.lx compiled on linux with egcs-1.1.2 (with the (...) (25 years ago, 6-Dec-99, to lugnet.robotics.rcx.legos)
 
  LNP not multitasking proof ?
 
Hi there, during my study of LNP i just stumbled across a point where i doubt it's not multitasking proof. it's related to transmissions of lnp-messages. lnp_logical_write() is ok, it waits for semaphore tx_sem at the beginning and posts the (...)

  Re: LegOS 0.2.2 on Win95 (almost)
 
I have helloworld.lx running on my rcx, compiled and downloaded with legOS 0.2.2 on cygwin and Win95! Rover.lx doesn't work right now, don't know why yet (i get 'unable to load legOS executable from rover.lx'). I had to use a little workaround. (...)

  IR proximity
 
I've managed to get a proximity detection working in legOS, using egcs 1.1.1 as the cross compiler. It has a very short range, and I haven't yet tested if the NQC variants have better range. If that is the case, I believe somebody will have to fix (...) (25 years ago, 1-Dec-99, to lugnet.robotics.rcx.legos)
 
  Re: LegOS 0.2.2 on Win95 (almost) - NOT
 
I finally succeeded in compiling an egcs-1.1.2 compiler for cygwin with the patch for enhanced RCX interrupt support applied. The bad news is: this doesn't change a thing. I still get "error deleting program". I can see the send light on the tower (...) (25 years ago, 1-Dec-99, to lugnet.robotics.rcx.legos)
 
  Re: LegOS 2.2 on solaris
 
G'day, (...) Do you know if/how they were able to fix the problem? Btw. I used binutils 2.9.1 and gcc 2.95.2 (with the patches for the interrupts applied) to create the legOS and gcc 2.8.1 to build the cross compiler. Carsten (25 years ago, 1-Dec-99, to lugnet.robotics.rcx.legos)
 
  Re: LegOS 2.2 on solaris
 
(...) You're right, that's the echo of what you're sending. This looks suspiciously like the problems many people had with gcc-2.9.5 compiled legOS on regular Linux boxes, you know. Maybe you should try downloading a kernel known to work? Markus. (25 years ago, 30-Nov-99, to lugnet.robotics.rcx.legos)
 
  Re: LegOS 2.2 on solaris
 
Hi Luis, thanks for your help. I tried both versions, the one using aioread and the one using the ioctl. Both run better than before, but still don't work (both give similar results). I now get signaled when I can read from the serial port, but what (...) (25 years ago, 30-Nov-99, to lugnet.robotics.rcx.legos)

Dave ... although at this point I'm not using non-standard firmware, I'd like to cast my vote for option (2). The command line may be a bit "unwieldy", but (2) gives the best solution. Thanks, - Nick - Dave Baum wrote: [snip] (...) (25 years ago, 30-Nov-99, to lugnet.robotics.rcx.legos)
 
  Re: problem downloading srec file to RCX
 
(...) In the process of adding support for quad-speed download to nqc I noticed a bug in the firmware download code that caused problems with short downloads. This may (or may not) account for your problem. Either way, the bug will be fixed next (...) (25 years ago, 30-Nov-99, to lugnet.robotics.rcx.legos)

Carsten- I asked a local solaris guru, and he wrote me what could be a helpful note on solaris aio. I've filed it (apparently) in the wrong folder, but I'll try to post it tomorrow.
