Because *all* of my free time has been consumed by a project. I expected 
this project to end September of last year! But, I *think* it's really 
starting to come to close. gpsim and SDCC are both high on my list. gpsim 
is at least stable and usable. SDCC is only partially usable. 

So I'm not sure on the exact order but these are my goals:

  -- update to a modern Linux distro (I'm running RH7.1)
  -- update my motherboard (400 Mhz is okay, but takes a helluva long
     time to compile gpsim).
  -- fix the (really long list of) bugs in SDCC
  -- expand SDCC's linker support.
  -- expand & fix gpsim stimuli
     o remove deprecated stimuli like the square wave 
     o add the usart module 
     o create a really usable waveform viewer
  -- Buy a Zaurus
     o Port gpsim to the Zaurus :)
  

Stay tuned, I'm coming back soon in full force!

Hello,
   I'm trying to run gpsim on a simple cod file output from
SDCC on a pic18f252. I'm seeing inconsistent effects:

  From the command line the .cod file sometimes loads, sometimes
does not. From the gpsim prompt, attempting to load the .cod file
results in an immediate segfault.

On the few occasions the code succeeds in loading, the effect
of breakpoints seems entirely arbitrary: the PC stops at points
where no breakpoint is set, other breakpoints are ignored, stepping
after a breakpoint works or doesn't, depending. There's a console message
about 'HLL not supported yet' ?? Should I be able to step through a simple
C app built on SDCC ?

The RAM view of eg T0CON registers seems unaffected by instructions setting
and clearing bits in the registers. Are internal regs in 18F252 simulated ?

I cannot get rid of console messages assuring me that symbols are not  
supported
in the font style chosen, I think I've tried every font setting offered.
Is this affecting whether or not the code module is loaded ? Where can
I find hints about Locale problems ?

   I have been running the CVS version of gpsim but I'm not able to get an
SVN update;  "SSL not supported" .. browsing on the web suggests I have to
build not only SVN but some app called Neon ?  Where can I find  
instructions
for getting SVN running ?

Can anyone offer clues for building the pty code needed in order for the  
USART
funtions to be available on systems other than BSD .. like core 4 ? I  
promise
to share ......

Thanks in advance,
polly

I am new to gpsim. Got the zip packags from SourceForge. Built gpsim & graphicled without
problem. lcd-0.2.9 complains about not finding install.sh.

I have a small project that will be using a 128x160 graphic lcd and the 18f252. When I execute the example I get a seqmentation fault when expanding the breadboard window.
