Anybody messing with teh new Arduino Yun?

[wb4jfi at knology.net]

Hey Mike.  That looks like another winner.  I am waiting for my Parallella 
board, which should ship the end of this month.  If I can find some more 
funds, I will [probably pick up a UDOO as well.  I like the integrated wifi. 
That's why I'm interested in the Arduino Yun... it may have a better wifi 
than the after-market Arduino shields.

One issue that I'm having with most of these boards that include wifi, is 
which wifi they are actually using.  I want to know the actual throughput, 
etc.  Most of the Arduino stuff is SPI, which is very slow.  The rPi wifi 
must be USB, and should be faster, except all the USB connectors share a 
single hub, IIRC.

Let me know how you like the UDOO.
73, Terry, WB4JFI

i have a UDOO coming. it's essentially a quad-core r.pi
with an integrated 'duino that takes the standard boards
plus has other connectors in the same spirit that pin-out
a bunch of other stuff too. there is also an integrated
connecton between the 'duino and the UDOO environment.
is has what looks like a serial link for existing code
that knows how to do that but it also has a much more
sophisticated facility that 'duino apps can use to
get services from the UDOO environment.

the UDOO comes in two major flavors - a dual-core and
a quad-core with minor flavors based on how much of
the aux peripherals are stuffed on the board. the cores
are 32-bit A9s (an ARM A9 an A8 with the multicore
stuff like cache coherency and interprocessor interrupts.
NOTE: Apple's "A" chip nomenclature is unrelated to the
official ARM designations.)

the dual-core UDOO has more memory than the r.pi,
a faster cpu with network interface, hdmi, and audio,
and it costs about the same. that's what starting a
year later will buy your!

I fully expect the quad UDOO to be able to run SDR software
pretty well even without tense code tuning to use, eg, the
NEON vector instructions in the A9.

fun for all what wants cheap springheadz!
