pic16f84a simulator help

Hi, one of my students is off to Cancoon for his christmas holidays,
the lucky beggar. He's going to miss some school but he's taking a
laptop, if i was 17 and heading to mexico from scotland, I would only
boot it up to gloat to friends left in the cold. Anyway, I downloaded
microdev the other night, it will do what I need it to do, only I
havent cracked it yet. Rather than expend heaps of braincells I
thought it would be better to check here to see what the
recommendations are for PIC simulators. The course I'm teaching is an
introductory one using assembly language and 16f84a, I'd like a
simulator that takes switch inputs, and simulates led outputs and
stepper motor output. Free is a good quality too. Microdev would fit
the bill if I can work it out.

thanks

Roy,

If the program you downloaded is the same one I saw here when I Googled
(http://sourceforge.net/projects/microdev/ ) , it looks like support ebbed
in 2006 (see "Project discontinued!!!!!" and two later posts), though it
looks like there may have been some downloads and development effort
recently. Let us know what you think of it.

Have you looked at the MPASM IDE from Microchip? It may not provide a pretty
graphical representation of switches and LEDs, but the students can set
(fire) input bits and observe output bits. It is a combination
editor/simulator and it is free.

Not a bad learning experience if students are willing to put a little time
into it.

Good luck with teaching the youngsters. Get'em interested!

sorted, after much fiddling about, i got microsim to work. My method:
1. draw the circuit in th simulator program, with great care, checking
each wire is connected after I draw it by loading a program and
running the simulation, it tells you there is a faulty connection, but
not which connection.
2. the program we use in school is "Picaxe Programming Editor" its
free, I enter and compile the program using PPE.
3. Back to the simulator, right click on the pic and load the hex,
then simulate.

my files are here, uDev is good for the level I am working at, my
students can now do programming at home, without hardware.
thanks for the help

p.s. which pic should I be using to teach 17 year olds?
