Arduino Goes ARM

The whole world seems to be going in ARM’s direction. ARM has practically taken the mobile phone and tablet markets. The latest version of Windows 8 will also run on ARM processors, Raspberry Pi is a $25 ARM based machine etc..

Slashdot tells that now the open source Arduino platform has a new member — the ARM-based Arduino Due announced at the Maker Faire in New York.

Due-300x300

The Due makes use of Atmel’s SAM3U ARM-based processor, which supports 32-bit Cortex-M3 ARM instructions. The SAM3U processor from ATMEL is running at 96MHz with 256Kb of Flash, 50Kb of Sram, 5 SPI buses, 2 I2C interfaces, 5 UARTS, 16 Analog Inputs at 12Bit resolution and much more. This is much more powerful than the current Uno or Mega.

Unfortunately the 3.3V operating voltage and the different I/O ports are going to create some compatibility problems. Arduino boards have been traditionally with 5V I/O, although 3.3V seems to become more and more popular. Adafruit has a tutorial on converting Arduino Unos over to 3.3v, from 5v. It’s becoming popular. The usefulness of 5V is diminishing.

I don’t see this new Due board as a direct replacement for the 8-bit ATmega based Arduinos, but more as a step up up for those looking for more processing power. A port to ARM for the user friendly Arduino toolkit had been long talked, but this is an official ARM-Arduino board with official support in the arduino toolchain.

To connect this board to Internet you will need to have some additional hardware, because Due does not have any built-in network interface. For Arduino use there has been long time Ethernet Shields (different models) and now also official Arduino Wifi Shield.

    I think this Arduino ARM version will face quite much competition from this ARM based cheap computer board:

    Finally, an ARM-powered Arduino
    http://hackaday.com/2012/10/03/finally-an-arm-powered-arduino/

    The ARM-powered Arduino DUE is going to be released later this month.

    Instead of the 8-bit AVR microcontrollers usually found in Arduinos, the DUE is powered by an ATSAM3X8E microcontroller, itself based on the ARM Cortex-M3 platform. There are a few very neat features in the DUE, namely a USB On The Go port to allow makers and tinkerers to connect keyboards, mice, smartphones (hey, someone should port IOIO firmware to this thing), and maybe even standard desktop inkjet or laser printers.

    The board looks strikingly similar to the already common Arduino Mega. That’s no mistake; the DUE is compatible with existing shields

    The Arduino Due is finally here
    http://hackaday.com/2012/10/20/the-arduino-due-is-finally-here/

    After a years-long wait, an ARM powered Arduino is finally due. The Arduino Due will finally be released this coming Monday.

    On board the Arduino Due is an Atmel-sourced ARM Cortex M3 microcontroller running at 84 MHz. The Due has an impressive list of features including a USB 2.0 host, compatibility with the Android ADK (lest you still need an IOIO), 12 analog inputs with 12-bit resolution, 2 analog outputs running at 12 bits, a CAN interface, and more input pins than you can shake a stick at.

    Although it’s not available right now, you will be able to buy an Arduino Due for $49 USD this coming Monday at your favorite electronics retailers.

    Microcontroller Maniacs Rejoice: Arduino Finally Releases the 32-Bit Due
    http://www.wired.com/design/2012/10/arduino-due/

    The long-awaited Arduino Due just hit the market, replacing the 8-bit, 16MHz brain of the popular Uno microcontroller prototyping platform with a 32-bit, 84MHz processor, while augmenting inputs and capabilities all around.

    For robotics and electronics hobbyists, its a moment of much excitement. But for the rest of us, what does this new controller offer over the older models?

    New Arduino Due Brings More Power To the Table
    http://hardware.slashdot.org/story/12/10/21/182216/new-arduino-due-brings-more-power-to-the-table

    “After six years in the making, the Arduino Due is finally becoming available and, with a price tag of $49, is bound to give a boost to the platform.The Due, which means 2 in Italian and is pronounced ‘doo-eh’, replaces the 8-bit, 16MHz Uno by a 32-bit, 84MHz processor board that also has a range of new features — more memory, a USB port that allows it to pretend to be a mouse or a keyboard say, 54 I/O pins and so on — but what lets you do more with it is its speed and power. The heart of the new Arduino Due is the Atmel SAM3X8E, an ARM Cortex-M3-based processor”

    Woah! I’m really enjoying the template/theme of this website. It’s simple, yet effective.
    A lot of times it’s tough to get that “perfect balance” between superb usability and visual appeal. I must say that you’ve done a fantastic
    job with this. Additionally, the blog loads very fast for me on Firefox.

    Outstanding Blog!

    If that vision comes to pass—and GE, along with other firms, manages to convince enough industries to sprinkle their products with data-gathering sensors—it could make troubleshooting a somewhat more streamlined process.
