Hi Stuart,

You may wish to post this message to GNUPIC mailing list too. There are
probably a few people there interested in a DOS-based freeware simulator.

As you may or may not be aware, I'm also writing an open-sourced
simulator which you can find here:

http://www.interstice.com/~sdattalo/gnupic/gpsim.html

However, since I'm a luser (a self-denigrating, semi-pejorative
description of a linux user), you'll find that gpsim works only under
Linux. Bob Cousins has made a port to windows/dos with the help of CYGWIN
tools.

Also, gpsim is currently text-based - there is no gui. It's been designed
to be fast. In fact it out performs a 20Mhz pic (on my 450Mhz PII). The
downside is that it's somewhat difficult to use (even for me!). Over the
last couple of weeks I've been making steps to improve the user interface.

btw, the info for joining the gnupic mailing list can be found here:

Regards,
Scott

Send it to me... I'll give it a shot.  Although I've never used the 16C54, I've worked with the 16C74 extensively.  Depending on your confidence in its accuracy, I'd be willing to (time allowing) use it to program my next project (without ever touching a hardware programmer until completion).  This project is relatively simple, even by PIC standards... the most difficult thing it will have to do is capture asyncronous byte every now and then off a port pin.

Let me know,

Vincent Deno

I think I could benifit from this.I am haveing trouble learning the whos
whats and whys of pic programming.I have struggled to get help ,please send
me a copy of your program.
