  Re: HOWTO going down
 
I'll put them up on Maktos.com's server! Just e-mail them to me. I'll send you the link when they're uploaded. Matt Luis Villa wrote in message ... (...) (24 years ago, 18-May-00, to lugnet.robotics.rcx.legos, lugnet.robotics)
 
  Can't get Windows compiler!
 
The main LegOS site has some MAJOR dead links! Does anyone have a mirror I could use? I need the Windows version of the cross compiler, etc. A LOT of links were dead...probly because it was a university server, and they all go down for the summer. (...)

  Re: local variables
 
(...) This is completely true and is basically a feature of the C language. Globals aren't technically "initialized" at all. They are just loaded as part of the image. You could consider that they are initialized at compile time. On a workstation OS (...) (24 years ago, 17-May-00, to lugnet.robotics.rcx.legos)
 
  Re: lnp communication question
 
Remember the medium... cheap IR basically stinks for transmission. You get transients from the lights in your room, the outdoors, yadda, yadda.

  Re: lnp communication question
 
(...) This suprises me. I have never heard of such high packet losses. How does dll do this? With some kind of ack and retry mechanism? dll seems reliable. Of course dll is going in the other direction. (24 years ago, 17-May-00, to lugnet.robotics.rcx.legos)
 
  Re: lnp communication question
 
You just pass an array and give the length, to send it. In theory you can send packets with a size up to 255 bytes (look in this group, the info is in here somewhere), but sending 1 byte has a packet loss of aprox. 1% and 4 bytes aprox. 10%, over (...)

  Re: local variables
 
(...) I think you're confusing the issue a little bit. LegOS only initializes GLOBAL variables when the program is loaded. So, for example, a global variable declared like: int foo = 4; Will only be initialized to 4 when the program is loaded. If (...) (24 years ago, 17-May-00, to lugnet.robotics.rcx.legos)
 
  local variables
 
Hi! I read that legOS only declared varibles the first time the program is run. Does this mean I cannot use local variables. I have loops in different functions using 'i' as looping variable, which is locally declared. Should I avoid this? Tobias (24 years ago, 16-May-00, to lugnet.robotics.rcx.legos)
 
  Re: lnp communication question
 
(...) So the length-argument tells lnp_integrity_write how many bytes to send? Doesn't that mean that it would be possible to send an array consisting of many integers, for example? How would this be done? (...) We plan to build a six-legged lego (...) (24 years ago, 16-May-00, to lugnet.robotics.rcx.legos)
 
  winlegos compiler problem
 
I am trying out the lnp functionality with addressing and such, and of course I had to recompile the legos kernel. That, in itself, seemed to go without a hitch, but when I later tried to compile one of the demo programs, this is what I got. djecho (...) (24 years ago, 16-May-00, to lugnet.robotics.rcx.legos)
