  RE: Logging sensor data
 
Hi nanobapt, Thanks for your help, I was sort of thinking along these lines. I know very little about LNP so apologies if I come across as a little ignorant. Is there an LNP server I can run on my machine to collect the data sent to the RCX tower? (...) (21 years ago, 9-Dec-03, to lugnet.robotics.rcx.legos)
 
  Re: Logging sensor data
 
(...) You can combine both solutions ... Storage in the RCX memory and then send it by lnp (after 10 data for example) You need to test :) nanobapt (21 years ago, 9-Dec-03, to lugnet.robotics.rcx.legos)
 
  RE: Logging sensor data
 
Hi nanobapt, What I tend to do is sample a sensor every say 20ms and log the data over a period of upto about 5 seconds. In your opinion what would be the best method, local storage or realtime streaming via LNP?, can LNP stream at this speed? (...) (21 years ago, 9-Dec-03, to lugnet.robotics.rcx.legos)

  Re: Logging sensor data
 
(...) How many time do you want to log it ? you can stock it to the RAM or send it by lnp .... nanobapt (21 years ago, 9-Dec-03, to lugnet.robotics.rcx.legos)

  Re: Strange RCX startup issues
 
(...) This was only a problem when using certain firmware downloaders. If you use firmdl3, then you should be fine. (...) As far as I can tell, I don't think there is any provision in BrickOS to call the constructors and destructors of globals & (...) (21 years ago, 9-Dec-03, to lugnet.robotics.rcx.legos)

(...) You can do make fontdesign in the util directory to create fontdesign.exe I have managed to get brickos-0.2.6.10 working using gcc 3.3.1 on win98 under cygwin, though I had a few problems along the way. At this stage I have only tried a few of (...) (21 years ago, 9-Dec-03, to lugnet.robotics.rcx.legos, FTX)
 
  Strange RCX startup issues
 
Hello, using brickOS v0.2.6.10... When I declare an object of type Motor and assign it a port outside of main() the RCX does not run the program at all, I have to remove batteries and reload firmware to get it back to normal. Is this related to the (...) (21 years ago, 9-Dec-03, to lugnet.robotics.rcx.legos)
 
  Re: Remote Message Buttons
 
That doesn't seem to help, doing things that way actually made the Stop and Beep buttons function as Stop and Beep. I was hoping to have all the buttons "raw" messages available to remap their functionality. I think I know how to modify the kernel (...) (21 years ago, 9-Dec-03, to lugnet.robotics.rcx.legos)
 
  Logging sensor data
 
Hi there, I'm quite new to the Mindstorms and LegOS/BrickOS scene but have recently begun using the kits for robotics purposes in University. They have been a revelation to me and speed up prototyping projects to no end. My question though concerns (...) (21 years ago, 9-Dec-03, to lugnet.robotics.rcx.legos)
 
  Re: Remote Message Buttons
 
(...) I just use the standard IR message stuff from BrickOS. They are normal messages, so this works just fine. Here are some lines of code: (I think it's in lnp.h) #include <sys/lnp.h> ... clear_msg(); ... if (msg_received != 0) my_message_value = (...) (21 years ago, 8-Dec-03, to lugnet.robotics.rcx.legos)
 
  Remote Message Buttons
 
Hello, Anyone had problems getting the message 1,2,3 buttons working with brickOS? All other remote buttons are working. I am using v0.2.6.10. I looked through the kernel and includes, it looks like in lr_process(), the lr_keys gets checked vs. (...) (21 years ago, 8-Dec-03, to lugnet.robotics.rcx.legos)
 
  Re: My problems with adding a Best Fit algorithm for memory management to kernel/mm.c

  Re: My problems with adding a Best Fit algorithm for memory management to kernel/mm.c
 
(...) Mark, Thanks again thanks for the reply. Yes, my main comcern is that the OS tasks move around only after the first power off & on, no time else. And also it was just a typo, the blocks are in order I was looking at the wrong copy of my layout (...) (21 years ago, 7-Dec-03, to lugnet.robotics.rcx.legos)
 
  Re: My problems with adding a Best Fit algorithm for memory management to kernel/mm.c
 
(...) So, if I understand you correctly, your concern is that the OS tasks move around the first time you power off & on, but not anytime thereafter? Assuming this to be the case, then: 1) When you first download BrickOS, there is a large chunk of (...) (21 years ago, 7-Dec-03, to lugnet.robotics.rcx.legos)

Mark, Thanks for the reply, and sorry I forgot to include some more details I have results from 2 memory scans (the values may be a bit off from each other (i.e. starting addresses, but that is becuase they are from 2 times I ran it, and I (...)

  Re: My problems with adding a Best Fit algorithm for memory management to kernel/mm.c
 
(...) Hi Mike, It would be helpful to see each of the memory block dumps and some notation as to what actions you took between each dump (i.e. RCX on/off, program downloaded, etc...) Mark (21 years ago, 7-Dec-03, to lugnet.robotics.rcx.legos)
 
  Re: My problems with adding a Best Fit algorithm for memory management to kernel/mm.c
 
Well, I have another problem - this time with Worst Fit. It may be becuase I have been looking at this code for so much time over the past few months, but I have encountered this problem with my implementation and my mind is boggled (as well as (...)
