Good find. Yes there has apparently been boards available to beta testers.
Looks like we might see something "real soon now". If the book really is released in July it would be a bit silly if there was no hardware for some of the subject matter.
Perhaps there are some minor problems they want to know fixed before finally releasing it?
Would be really happy, if this could find a way to us within this year ...
I want to use Arduino for a bigger project, but there is the need of 32bit due to operating system support.
"You'll learn all about the changes in Arduino 1.0 and the new ARM-based Arduino Due. "
The way I read the information about the book, I think they are going to repeat things about the Due that we have read in the press releases. I don't think they are going to teach you how to use the Due.
There isn't much info on the Arduino Due or the Arduino Leonardo.
The arduino due was supposed to be released last year although I'm sure that they hit some issues and that was just a projection. The onboard usb support will be nice, no stupid FTDI chips I believe.
Yes I've all but given up on the Due, but why hasn't the Leonardo been released? After all there are so many clones out that the details are not secret (unless they change it).
Both of these boards should be easy to design for the hardware, maybe the delay is in getting a new IDE/tool chain working.
Yes the Optiboot and the new version of the IDE are certainly putting them back.
I don't think they'll be pursuing the Leonardo any more for the sole reason that there are so many out there that are exactly what the arduino people would make.
You should check out AERY32 http://www.aery32.com/ . It's easy to use, cheap and very very tiny. Been playing with one for a few days now and I love it :).
General consensus seems to be that it will be announced at the NY Maker Faire on the 29th (tomorrow or today depending on where you are). Masimo hinted to that on another thread.
If that turns out not to be the case then I think it's time to officially give up
Yay, I don't think there will be any surprises in the hardware but I am very interested to see the toolchain being used. Please have the option for a real IDE and debugger.
Given the obvious support from Atmel I'm betting on a version of AVR Studio6 with Arduino Due support.
