Leaf labs is something to check out for those interested:

Tried to use an STR910F, a 96Mhz ARM with 288k flash and 64k RAM 3 years ago but gave up on it.

STR910F

It could flash properly but it wouldn't run anything, probably because of clock jitter due to the protoboard. They were $10 & needed bulky protoboards. Now ARM's are cheaper than 8 bit microcontrollers & custom SMT soldering is easy, not that you should build your own instead of buying one from xduino.com.

Once the Arduino brand is standardized on ARM, 8 bit microcontrollers will probably die quickly.

Agreed. Can't wait to see these out in bulk as well. I beleive the Xduino guy is having out-of-stock issues as well. I'll try contacting him to see if I can get the board schematic.

Great find Jonathan, looks promising. I like the 12 bit ADCs and the crazy number of inputs. This thing has potential for sure.

I buy what seems to be the same board, and they seem to have in stock:

Great find Ernani! I do beleive its the same. On the Xduino website he mentions he sources the (complete) board from a local supplier. However his big 'innovation' is to port all the arduino syntax and similar compiler & ide so that we have access to all the features at a fairly high level. ARM cpus are notoriously expensive to dev on (the chips are cheap but the compilers and dev environments are very expensive for commercial use). So this progress by the Xduino guy (I should really find his name) will certainly be very welcome.

If I was in charge of product development at Atmel Corp. I'd stop wasting money on all of the stupid stuff corporations do and redirect it towards hiring a 5 man software engineer swat team, ASAP. They would be tasked to create a full Arduino port for XMEGA (open source of course), support all of them, not just one . . . , and get it done by end of Q2, 2010. Add Arduino XMEGA Extended commands that would take full advantage of the new architecture. Add AVR Studio and JTAG debugging support.

Atmel could stave off the inevitable barage of newcomers that's bound to happen (ie ARM, Microchip)

The new arduino specs could look like this:

CPU: ATxmega64A1 to ATxmega384A1 (64K to 384K)
CPU CLOCK: 0 – 32 MHz @ 2.7 – 3.6V


Non-Volatile Program and Data Memories
– 64K - 384K Bytes of In-System Self-Programmable Flash
– 4K - 8K Bytes Boot Section with Independent Lock Bits
– 2 KB - 4 KB EEPROM
– 4 KB - 32 KB Internal SRAM
External Bus Interface for up to 16M bytes SRAM
External Bus Interface for up to 128M bit SDRAM
• Peripheral Features
– 4-channel DMA Controller with support for external requests
– 8-channel Event System
– 8 16-bit Timer/Counters
4 Timer/Counters with 4 Output Compare or Input Capture channels
4 Timer/Counters with 2 Output Compare or Input Capture channels
High-Resolution Extension on all Timer/Counters
Advanced Waveform Extension on two Timer/Counters
– 8 USARTs
IrDA modulation/demodulation for one USART
– 4 Two-Wire Interfaces with dual address match (I2C and SMBus compatible)
– 4 SPI (Serial Peripheral Interface) peripherals
– 16-bit Real Time Counter with separate Oscillator
– 2 Eight-channel, 12-bit, 2 Msps Analog to Digital Converters
– 2 Two-channel, 12-bit, 1 Msps Digital to Analog Converters
– 4 Analog Comparators with Window compare function
– External Interrupts on all General Purpose I/O pins
– Programmable Watchdog Timer with Separate On-chip Ultra Low Power Oscillator
– JTAG (IEEE 1149.1 Compliant) Interface for programming, test and debugging
– PDI (Program and Debug Interface) for programming and debugging

Write your congressman today.

Just for example...wouldn't this be nice:
Megavore (XMEGA 128A1 Development Board)

I hope Atmel hears this they need some fresh technology to move ahead... Very few cars in the parking lot here in Colorado Springs, This could boost them greatly..

Comment by ernani reis on January 22, 2010 at 7:21pm

did anybody get to download the xduino? I put my email there, and nothing happened.

Comment by Tim Michals on January 22, 2010 at 9:36pm

I'm waiting on a board from http://code.google.com/u/opendous/
Here is a follow=up email...

Same with the LPC1768 design. I am in the
process of perfecting the LPC1758 design, which I am very proud of as
it crams everything into 3 square inches (3" x 1") - USB-miniB, USB-A,
USB switch, microSD, Ethernet, Cortex-M3 JTAG, watchdog crystal, and
exposes all non-ethernet/USB pins on its headers. It will go on sale
when I finish the design and figure out the financing for a sizable
lot.
