Hi HN, I work at LeafLabs, we are responsible for a 72MHz, open/libre licensed, ARM microcontroller platform called Maple. The header spacing issue on Arduino was really a gaff! We actually provide a 1/10" compatible secondary header as a rough-fix on Maple. We get tons of use out of this! Maple line boards are based on the 32-bit ARM Cortex M3 processor core. These low power procs don't have MMUs, so unlike ARM9, th…

I would love to play with a Maple mini. How do I get one?

Wait just a little bit longer ;) You should hear some news about this on our blog within a week. leaflabs.com/blog

Agree. The arduino processor is also pretty weak given the price/performance ratio. I'm in favor of seeing them work with say an arm-5 or arm-7 device.

Yeah, I'd love to see someone make an open-source ARM9 board that runs Linux, but works with Arduino stuff, and has good libraries for controlling the hardware. The first version of the Chumby Hacker Board was a good candidate, but they removed the Arduino headers on more recent versions.

Like this? http://beagleboard.org/

EDIT: sorry I was under the impression the hardware spec was open source, I guess I'm wrong.

It's a seriously exciting time to be a developer. Or to be alive in general, really. Growing up in the shadow of our failure to colonize space, it was easy to imagine that history had basically stalled and there wasn't much left to hope for except an uneventful decline. Added to that, all our interesting problems were too big for an individual to hope to solve. Instead, the ability for individuals to meaningfully inn…

I have yet to meet a dead person that's excited to be dead.

I'm 100% delighted that Google chose to standardize on the Arduino platform, but I fear it means we'll now be stuck with the infuriating 0.160" header spacing between shield pins forever. Background: http://brettbeauregard.com/blog/2009/07/arduino-offset-heade... Here's the explanation of how the bad spacing happened from Massimo Banzi: http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1212632541 (scroll down 10-15 pos…

I'm not sure what you mean by weak in terms of price/performance ratio; the ATmega328 used in the Uno can be had for $3 (and way less in bulk).

I notice that the STM32 line is actually priced on-par (or cheaper) with the ATmega chipsets, yet offers considerably more functionality (and speed).

As compared to Atmel's 8-bit MCUs, what are the downsides to the STM32 for most applications, if any? Obviously there's the packaging ...

Thanks!

Heh, me too--how long did it take you to write up your post? It would've been useful, ah, 8 hours ago. :) I've tested a revision 1 SparkFun USB Host shield and UNO/Duo with pin define fixes and a Nexus One with Android 2.3.4 and the DemoKit app. It "works" but seems a bit flakey needing multiple resets to move from detecting to data transfer. I'm suspecting possible power related reset issues. Unfortunately my usual…

Hah, I got it working yesterday but I had other stuff to do and I wanted to patch their code to work on both 168/328p and 1280/2560 before doing a proper write up. Can you test my patch and get back to me whether it works for you? That way I can update my post.

Have checked your patch and commented here: http://romfont.com/2011/05/12/google%E2%80%99s-open-accessor...

Have also put up some photos of input/output example of Arduino Uno + Usb Host Shield + Nexus One here along with some code: http://rancidbacon.com/p/android-arduino-accessory/
