Open source AVR simulator.

[Ian Field]

Is there such a thing as open source AVR simulator anywhere?

Some kind of development environment that I can experiment writing & running
code without going near a soldering iron.

Thanks.

[Daniel Pitts]

Well, you can skip the iron if you just use an Arduino.

I think AVR studio comes with a debugger, I don't know about a simulator
though.

Do you think I'd have better luck finding one that runs on a Linux box?

I have an extra PC gathering dust that only needs the very basic hardware
putting in it.

The AVR seems to have the longest heritage with its 8051 ancestry, but the
PIC seems to have a wider scope of support these days.

Do you know where to find a reasonably concise overview of the 2
architectures?

Maybe I should take a closer look at the relative merits before deciding
which way to go.

TBH; the old "conventional" architecture seems to make more sense to me!

Thanks.

There's a program called simulavr which seems fairly complete,
although I have not yet got around to compiling it. To compile under
Windows you need the MingW environment, which presumably includes the
GNU compiler chain. Someone probably has a pre-compiled executable
for download somewhere if that's what you need.

There should be a special word in the English language to identify
people who create problems and then turn around and offer up their own
tailor-made bogus non-solutions designed to completely avoid the root
causes of the situation under consideration. 'Traitor' might be a
good choice, but lacks the requisite specificity. One of the problems
with contemporary English is it lacks many such words that would
otherwise categorically identify certain kinds of person, place, or
thing -- making it difficult or impossible to think analytically about
such objects. These shortcomings of the English lexicon are
representative of Orwellian linguistics at work in the real world.

If its a natively Linux app - I could probably live with building up a Linux
box for it (eventually).

[Uncle Steve]

It appears to be a fairly standard autoconf configured program, most
likely later ported to run under Windows.

Yeah, EG: simulavr, iirc it can plug into ngspice.

yeah, install debian, the package is called simulavr.

(info from debian)
--\ Depends (4)
--- dpkg (>= 1.15.4) | install-info
--- libc6 (>= 2.7)
--- libncurses5 (>= 5.5-5~)
--- libtinfo5
--\ Recommends (3)
--- binutils-avr (UNSATISFIED)
--- gcc-avr (UNSATISFIED)
--- xterm


ncurses, tinfo, xterm.

looks like a CUI program, so should compile fairly easily under mingw.
modulo gratuitous use of fork() or other non-windows features.

I don't see much 8051 in the AVR.

When I have my software-writing hat on, I loooove the AVR.

When I have my parts-procurement hat on, the PIC looks better (although
that's based on old information -- Atmel used to be bad at delivery but
has reputedly gotten better).

When I have my hardware-designing hat on, I loooove the PIC.

Get an Arduino and a debugging environment. Nothing says "embedded" like
a blinking light.

Better yet, particularly if you like Linux, chuck the 8-bit stuff and
find a nice Cortex M0 development board.

Thanks - a fair bit to digest there.
