  RE: Displaying info while debugging
 
(...) Mario, I did some checking and I think the real issue is with the USB driver from LEGO. The serial tower does not exhibit this behaviour. It has its own problems, which include falling asleep after 2 seconds of inactivity. So, as far as I can (...) (22 years ago, 2-Jul-02, to lugnet.robotics.rcx.pbforth)
 
  Re: pbForth vs RCX 1.0
 
(...) Yes, please :-) I actually knew the EMIT and KEY words, but had never thought of using them to make two RCXs communicate. For some stupid reason in my head I was expecting some special API words was necessary to manage this communcation, while (...) (22 years ago, 2-Jul-02, to lugnet.robotics.rcx.pbforth)
 
  RE: Linux driver for USB tower
 
(...) Richard, That's great, but I just realized there is no URL....how can we test it if we can't find it? :-) Cheers, Ralph (22 years ago, 2-Jul-02, to lugnet.robotics.rcx.nqc, lugnet.robotics.rcx.pbforth)
 
  RE: CPR for RCX?
 
(...) ld is a linker. It takes the object code generated by the assebles and "links" it together to form an image that can be loaded. The file: ld/h8300_rcx.ld specifies how the objects are stiched together. (...) No, the firmware uploader splits (...) (22 years ago, 1-Jul-02, to lugnet.robotics.rcx.pbforth)
 
  Re: CPR for RCX?
 
(...) I knew Assembler would come into play sooner or later. I have downloaded a copy of the H8/300 Assembly language spec. What I still don't understand is how you turn the object code into 'S'-type records with 'ld'? (...) Can I assume the RCX has (...) (22 years ago, 1-Jul-02, to lugnet.robotics.rcx.pbforth)
 
  RE: pbForth vs RCX 1.0
 
(...) What you describe would work exactly. Normally, the "outer interpreter" of pbForth waits for input using "KEY" - which of course is just a char from the IR. You can make a special word that waits for anything you like... Cheers, Ralph (22 years ago, 30-Jun-02, to lugnet.robotics.rcx.pbforth)
 
  RE: CPR for RCX?
 
(...) You're pretty much OK until point 4. TCL is used to compile the pseudo code for pbFOrth into assembler source code. From there the GNU as program assembled the object code and ld links it and eventually produces the S records. S records are (...) (22 years ago, 30-Jun-02, to lugnet.robotics.rcx.pbforth)
 
  RE: Linux driver for USB tower
 
(...) Richard, this is great! What device name does the new tower driver use. I hope to be able to use my Tcl/Tk GUI for this purpose. It would be really great to get USB support for pbForth into the Linux world. The serial port has always been (...)

  Linux driver for USB tower
 
Hi, I have a working linux driver for the lego USB tower; so far it has only been tested on kernel 2.4.14 on a uhci system, where it has worked without any problems. Anyone feel like testing it out on their own system (to use it, you will need to be (...) (22 years ago, 28-Jun-02, to lugnet.robotics.rcx.nqc, lugnet.robotics.rcx.pbforth)
 
  Re: pbForth vs RCX 1.0
 
Thanks, Just to make sure, let's take an example. Let's say that I have two RCX, named A and B. What if the program in RCX B is waiting for a character on the instruction KEY and RCX A sends a character, let's say '5' (ASCII 52) with 52 EMIT ? That (...)

  pbForth vs RCX 1.0
 
Hi, Is pbForth fully compatible with RCX 1.0? Can RCX 2.0 communicate with RCX 1.0 in pbForth (using IR ports)? Thanks Mario (22 years ago, 26-Jun-02, to lugnet.robotics.rcx.pbforth)
 
  pbForth questions
 
The output of my compiler typically looks like: \ Begin code sample FORTH CODE ... ... : ENTRYPOINT ... ; 0 ENTRYPOINT \ End code sample Or, in other words, I'm currently (and this isn't permanent) not allowing programs to be compiled that do not (...)

  RE: Displaying info while debugging
 
Mario (and all other pbForth users - both of you :-) I'm very happy to include ANY contributions that you may have in the source archive. Even if I don't update the actual core, I still add useful scripts to the distribution all the time. Any (...) (22 years ago, 17-Jun-02, to lugnet.robotics.rcx.pbforth)

  Re: Terminal Emulator

  Re: Displaying info while debugging
 
Hi David, If I can come up with anything usefull, I could post the source code here or send it to you by e-mail. Again, I think it's best that M. Hempel keeps the core small and that we add extensions to that core. Excuse my ignorance, but what is (...) (22 years ago, 16-Jun-02, to lugnet.robotics.rcx.pbforth)
 
  Re: Displaying info while debugging
 
I agree that pbForth is GREAT! Hopefully you're forwarding all your debugging words to Mr. Hempel. I noticed on the c.l.f. newsgroup in a message called 'Small terminal emulator' that Lionel Rogers is writing an introduction to programming book (...)
