  WINLNP QUESTIONS
 
Dear all, I have some troubles setting up WinLNP. I am new to RCX (2 months) and legOS (1 month) and have not much experience with VC6. I want to set up a line of communication between PC and RCX. I downloaded everything from (URL) and I managed to (...) (23 years ago, 13-Aug-01, to lugnet.robotics.rcx.legos)

(...) One other thing, did you erase the firmware from the RCX before trying to load legOS? regards Frank Caggiano "The best education for the best caggiano@crystal-objects.com is the best education for all."

(...) Did you try using the slow mode option ("-s" for firmdl3) as was suggested? (23 years ago, 13-Aug-01, to lugnet.robotics.rcx.legos)
 
  Re: transfer data failed
 
Hi, thanks for the tips, but nothing helps. I tried 0.2.5, I tried the far and near mode, I changed the lighting conditions -> nothing helped. But I don't think that I fired up my Brick/Tower because the original Lego Software under Windows works, (...) (23 years ago, 13-Aug-01, to lugnet.robotics.rcx.legos)
 
  Re: transfer data failed
 
I use 0.2.5 in windows (djgpp), and can't get by without using the slow download option (-s). If you have lighting problems, perhaps flipping the little switch on the IR tower will help. When I download stuff at school, it helps to have it set to (...) (23 years ago, 8-Aug-01, to lugnet.robotics.rcx.legos)
 
  Re: transfer data failed
 
(...) I am using 0.2.4 under windoz and have had similar problems. I found that I must use the slow download option (-s) for the firmware to load properly. regards (23 years ago, 7-Aug-01, to lugnet.robotics.rcx.legos)
 
  Re: transfer data failed
 
(...) Hi, i use 0.2.5 under Cygwin and sometimes i experience the same problem. I dont think its a problem with the legOS 0.2.4 distribution. The problem often occurs if its too dark or too bright in your room. It also happens if sender and receiver (...) (23 years ago, 7-Aug-01, to lugnet.robotics.rcx.legos)
 
  transfer data failed
 
Hi there, I use legOS 0.2.4 under Linux and tried (after a few weeks) to download the firmware and get always the follwing error: firmdl3/firmdl: transfer data failed Batteries are brand new, tower was set to short and long dist. nothing helped ...

Maybe have a light near the tower that starts flashing when it (...) (23 years ago, 4-Aug-01, to lugnet.robotics.rcx.legos)
 
  Re: about lnp_integrety_write
 
(...) Hi, the function does exactly what the name says...it sends a LNP integrity layer packet of given length. Anyway the function seems to be unused. lnp_addressing_write() is e.g. used to send the acknowledges in program.c, which makes perfect (...) (23 years ago, 3-Aug-01, to lugnet.robotics.rcx.legos)
 
  about lnp_integrety_write
 
anyone know what this function does? i could get no reference to it under the legOS howto written by luis villa. ive tried sending messages both with it and without it and it seems to work anyways. regards kenneth johansen kennethj@stud.cs.uit.no (23 years ago, 3-Aug-01, to lugnet.robotics.rcx.legos)
 
  Re: Is this an error in legOS 0.2.5?
 
(...) Hmmm, yes, you are right. In fact it woudn't make sense. My actual robot uses a little neural net and if battery goes low, the actual data will be sent to the PC to be saved. For this, it would be nice if the RCX makes some noise, I grab it, (...) (23 years ago, 31-Jul-01, to lugnet.robotics.rcx.legos)

In effect, changing the batteries is equivalent to the (...) (23 years ago, 30-Jul-01, to lugnet.robotics.rcx.legos)
 
  Re: Is this an error in legOS 0.2.5?
 
So in the original firmware, the system is shut down if ultra-low battery is detected. If we don't want tot do that, we could change the ">" in the 2nd compare to a "<" to get some hysteresis. Or would it be usefull to stop legOS and do a shut-down (...) (23 years ago, 29-Jul-01, to lugnet.robotics.rcx.legos)

  lnp logical layer and collison detection

  Makefile Design - Observation, and Query to Paolo Masetti
 
The latest CVS version of legOS adds explicit detection of CygWin 1.1 (and by extension 1.3) This did, however work anyway, with Cygwin 1.1 being detected alongside the older cygwins, due to a quirk in make's findstring - specifically, that: (...)
