EDIT: Just created an SVG, it had two issues but I uploaded anyway. It looks like crap in a browser, can you guys try in a graphics program.

I fixed the issues (it uses SVG fonts, which browsers other than Opera don't support). Inkscape loads it and I re-saved from that, then used scour to get rid of needless bloat. Graynomand, if you pm me your mail address I will send you the fixed versions (work in Firefox, IE, Chrome, Opera).

Top left of the excellent diagram, explaining the color coding: "per A" / "Per B or X" - I am confused what the little black corner signifies. My guess is that the data sheet (AT91SAM) shows two variations a -A suffix and -X suffix. Is that it? And if it is, does it matter as the DUE probably comes with the same chip variation. The offical product page says SAM3X8E.

The IO Controller provides multiplexing of different Peripheral functions on a single pin, either A, B or extra (X).
This is a way to select one of them.
For more info, check the datasheet sections 11.3 and 32.5.3.

What Dancombine said.

Actually I've been wondering if it's worth differentiating the peripheral mux option used. After all it has no real bearing on the average user and more experienced SAM users will either know this or will soon find out.

@Nantonos
I'll PM.

New version just uploaded, just a few layout changes, I think we're almost ready to call this done.

I didn't upload a new SVG, it blew out to 2Mb for no obvious reason. I'll work with Nantonos to get a good SVG file.

I was under the impression that pin 50-52-53 also had something to do with spi?

Rob,

Actually yes, you're right. This might confuse the readers of the pinout. And when one is really in the weeds of selecting alternate peripheral pin functions, he would have to open the datasheet anyway to select the right register bits.

That's on the Mega, with the Due SPI is only available on the 2x3 SPI header.

New version uploaded.

I'm still happy to implement any good ideas and of course fix bugs, but I think we're just about done here,

Then I really don't understand why I cannot make work, those where the first ones I tested.

Then you'd better start a thread in the Due section of the forum. Post your code and people will check it out. It could still be the diagram but that's unlikely now I think.

This glorious diagram is a great example of why I chose Arduino for my microcontroller dev/proto platform.  The community here is top-notch.  Thank you for the work, sir and well done!

Hi,

Very nice job this diagram !

I just would like to give my opinion on one thing :
I think you have already discussed this, but I'd prefer to have both peripheral A and B indicated.
To be honest I will print this layout and add some manual (and dirty) writing about periph A/B, so in my opinion it would be better to have it directly on the diagram...

Anyway, thanks a lot for your work!

Thanks djjoshuad and dammien.

@djjoshuad dammien
We decided (well I think it was me and one other person but nobody disagreed smiley) not to add that level of detail, so I'm afraid you'll have to get out the magic marker as I've moved on, I'll fix errors but have other stuff to do these days.
