Conference 10/4-6 at Santa Clara Convention Center
NU Horizons Corp. has a free seminar on 11/01/2005 in SJ and an
inexpensive OKI AME-51 ARM evaluation board - $199.

The latest Atmel monstrosity-on-a-chip:
Atmel's latest multiple-kitchen-sink ARM chips: AT91SAM7X128 and
AT91SAM7X256 (respectively 128k and 256k of onboard flash).
They have (all on-chip): Ethernet, USB, CAN, IIC, 3 UARTs, 8 interrupt
Multiple UARTs are extremely important for doing central system control
with serial peripherals like motion controllers and smart touchscreens while
keeping a tethered link to an "operator" task. MPE Ltd. and Forth
Inc. both have tethered development systems for the ARM. With multiple priority
levels, interrupt-driven programming is still a hassle, but less than without
The "7" after SAM means that these chips have the ARM7 core
(not ARM9 -- pay no attention to the "9" after AT). Atmel claims that
by avoiding the need for code shadowing, they have "uniquely"
realized the ARM7's potential for true deterministic execution times.
The parts are astoundingly cheap: "The AT91SAM7X128 is available
now in a 100- lead LQFP green package for $7.20 in quantities of 10,000. The
AT91SAM7X256 comes in a 100-lead LQFP green package for $8.65."
This looks like a universal solution for realtime complex machine
control and instrumentation.
The low-cost ARM board I recalled from comp.arch.embedded uses the Atmel
AT91SAM7S64, a less-stuffed sibling of the above chip, and sells for the
attractive price of $60.
