Started by deepak August 27, 2003
Softbaugh have an evaluation board for the 169. It is currently sampling 
in limited numbers. It has not been fully released yet.

Beginning Microcontrollers with the MSP430

Yes, I actually received one of those boards (D169, I think) a
couple of weeks ago through a TI 'class' on the product line.
Had to send out for the little JFPC adapter.  Unluckily,
Softbaugh was charging some US$10 for it.  Luckily, TI had just
(the week before) arranged to provide it for free.  And it
arrived in short order.

Hi Jon, you're really lucky, us antipodean dwellers get largely ignored, 
not even a sniff of a possible course. I don't really want the course, 
just the tools, and the chips at cut price, perhaps I should ditch the 
MSP430 altogether and switch to something more ANZAC friendly. When the 
courses finally do get to us they'll be regular price anyway going by 
past performance.

That's sad because I've met and talked with some most excellent
people over there and plenty of quality activity going on there.
There's certainly no business cause I can think of.  Makes me
mad.

>I don't really want the course,

Hehe.  Completely agree.  You'd learn ZIP from the course.

>just the tools, and the chips at cut price,

Yes.  They also gave me a secret code for a discount price on
the FET140 tool ($49) which I'm sure anyone could use, but
nothing for ordering one of those D169 boards.  (Should I post
the code here?)  I haven't checked Softbaugh, but do they sell
them to your area yet?

I feel the frustration you're expressing.  I'd be upset, too.
Just seemed like TI is international enough to have gotten all
this right.  Maybe the problem is that the MSP430 group is
depending too much on 3rd parties to leverage their growth, or
upon 3rd parties who aren't as international as TI is and thus
it brings the whole thing down to that lowest common
denominator.

What *is* ANZAC friendly, by the way?

I'd have imagined that TI would have been easily able to work
out the logistics of working with disty partners or others in
Australia.  Heck, their partners would do the real work for
them, I'd guess.  Should be mostly just a matter of passing on
their plans for the US, to give a leg up.

ANZAC was the term given to the Australia New Zealand Army Corps, in 
WW1, most treateis aetc between the two nations are now referred to as 
ANZAC. As well as the ANZACs being a sourc of extreme National pride 
here, the term is now commonly used when referring to the two nations 
together. Very few manufacturers of anything are actually ANZAC 
friendly, we tend to be viewed as an insignificant market, so cop the 
left overs at premium prices

Courses are usually run by the Disties, but the last one on the MSP430 
(the first one, when it was nearly new) I effectively conducted. At that 
time I'd been playing with the parts from their preproduction days. Here 
the disties used to be first rate for service. Some still are OK by 
current standards, but the locAl companies that used to handle the 
bigger accounts, like Ti, Moto etc have all been eaten by Arrow, Avnet, 
and other offshore monsters. This has gemnerally been for the worst. 
They've stripped them down to bare minimum staff, instituted huge MOQ's, 
and rarely if ever hold stock of anything. They used to have quite cluey 
FAEs, but, for the most part these were lost in the name of the god 
excess profit. There are good guys out there, and it's very much staff 
dependant. For years Avnet were great, responsive and supportive, even 
though they'd been stripped to just one guy and his receptionist/ jack 
of all trades. At the same time Arrow were just the opposite, didn't 
show for meetings, had to be constantly chased for data, etc, then Avnet 
employed two guys from Arrow, Arrow moved their old FAE guy to sales. 
The new people at Avnet were blind deaf and dumb, while the new guy at 
Arrow has been really great. Future Electronics is a nightmare since it 
arrived here, but I think they're Asia based. Anyway I and several 
others have placed orders for Lumiled LUX V modules, the first nearly a 
year ago. Still haven't seen any.
