  Re: some more questions about lnp.
 
The frequency of the RCX's IR does not change at all: " The RCX uses a 38kHz carrier, which is pretty typical for TV remotes. As for the sampling rate, the RCX runs at 2400 bps, which makes each bit approx 417us " (URL) think the only way you could (...) (22 years ago, 28-Sep-02, to lugnet.robotics.rcx.legos)
 
  Re: some more questions about lnp.
 
duh... guess i was kinda wrong here.. IR is in reality a frequency defined from A to B. any messages sent within this spectre is said to be IR messages. so in theory sending an IR message closer to A than B from one RCX. and at the same time sending (...)

  Watch Dog Timer on the H8
 
Has anyone been able to make use of the Watch Dog Timer on the RCX? The H8 documentation seems to spell out the workings quite well. BrickOS (LegOS) has minimal support (a vector is declared for both NMI and overflow) and pbForth files list the WDT (...)

  some more questions about lnp.
 
ok, im back again with even more questions. when i created my last program using lnp on an RCX i did a mistake by setting the same port as the one im listening on and the one im sending on. this made me think. what is the reason we use two different (...)

  Update for DJGPP version
 
Here is an update for my (slow) progress for creating a DJGPP compatible or port of brickOS. At this time I am solely focused on getting a cross compiler built and putting off other issues (such as tty comms, see (URL) I have tried three methods to (...)

  some measurements in lnp, please comment!
 
hi all, i have made some measurements with lnp in legOS 0.2.4 under ideal conditions (dark room with minimal load on PC and RCX) and found that sending a 10 byte message with lnp_addressing_write averages on about 0.06136 seconds (+/- 10 ms for time (...)

  Re: How to setup gcc and make in cygwin

  Re: How to setup gcc and make in cygwin
 
Actually there is a set of updated instructions for Windows with the most recent being for brickOS. brickOS is the continued development effort foe legOS. AT the request of The LEGO Group the name has changed. So the most recent information can be (...) (22 years ago, 16-Sep-02, to lugnet.robotics.rcx.legos)
 
  Re: Pass by reference
 
Ralph, The second parameter to the task is a pointer to an array of pointers. Those pointers (under DOS and other OSes) normally point to parameters on the command line (string data). However, there is no reason to not use them for other data types. (...) (22 years ago, 16-Sep-02, to lugnet.robotics.rcx.legos)
