'[EE] Speaking of MSP430'

With all the recent discussion of the MSP430, I was wondering if someone
who has started using it could give me an idea of how they got into it,
and how difficult they found it to program versus your typical 8-bit AVR
or PIC? I assume you would have used C to program the MSP430, but
perhaps you used assembly? Did you learn assembly before C, as we tell
everyone who starts with the 8 bit MCUs? What development board did you
use? What would you do differently/ what problems did you encounter?

If someone answers those questions I'll put them on a webpage for other
people to see ;-)

Thank you,
Martin K

Since you're talking about /switching/... IMO the rule of "learn asm first"
applies mainly to the first MCU you're learning to understand. Once you
have understood one, for me it's more efficient to use a compiler (assuming
that you want to program in a higher level language than asm -- if not, the
question is obviously moot :) and learn the necessary asm by looking at the
compiler output. There is not really a big advantage in learning to
fluently write the target assembler if you don't want to program in it.
That time is probably better spent finding out how exactly the peripherials
diverge from the datasheet :) -- which can be done in any suitable
language.

techref.massmind.org/techref/ti/msp430/index.htm Pretty good start,
nice description of the special features of the instruction set / core.

Please consider adding what you find to that page?

I also have some macro code that simplifies the set up of the serial ports
which I am negotiating to get out from under an NDA.

Any interest in a [MSP] tag?

I've pretty much decided to take up the 430 for myself. The ultra low power
/ high speed capability makes it ideal for the sort of projects I'm most
interested in. e.g. environmental logging, wearable computing, garden
automation.

You might want to look at my "trip report" from 2000:
  http://www.geocities.com/westfw/trip-report-msp430.txt

Some of the data in there may be obsolete, now.

I general, the 430 seems to be a general 16bit von-Neuman architecture
part, somewhat more pleasant to program than most 8 bit chips (including
PIC and AVR.)  However, in my case, the hardware-friendliness and
pricing
of the PIC and AVR (drive current, packages, group buys on PICList, etc)
have caused me to neglect the 430 after my initial interest.  (and not
having a need for extremely low power consumption.)

I would welcome an MSP tag.
The yahoo group has some toolchain vendor representation
but overall IMO strike me as somewhat elitist and intolerant.
I'm not likely to ask a second question there.

Do we really need another tag? Just look at the [AVR] tag...
ARM is nice, do we need [ARM] tag? The problem is that
it is not so easy to attract people to a new mailing list.

As for the Yahoo MSP430 group, I always use Gmane to read it
using a newgroup client like OE or Thunderbird. I do not use it
so I have no questions to post yet. I agree that there are some
people there kind of intolerant...

And there is the Yahoo LPC2000 group. I think it is better than
the Yahoo MSP430 group but stil there are vendors inside. I
actually think it is a good thing to have vendors inside. PIClist
is apparently very different that there are no obvious
Microchip/HiTech people posting here.

I do find it kind of funny. I have learnt SO much here
but did not see any Hitech or Microchip engineers
posting here. Why is that?

My guess would be that they can't figure out how to sort messages by
tag. Trying to read this group without tags and threads would be
intolerable for me. I also subscribe to a few other lists and get a few
hundred emails a day.

Fear of exposure through the high quality of the list? :)

There are quite a few vendors here, though: Olin and Walter Banks are two
that come to mind, but there are a few others.

I think they all discuss on their own forums. But my question is why the top
posters of Microchip forums' join PIClist community? Some of them has much
experience and knowledge than Microchip stuff :)

Not yet, anyway.  I believe the AVR tag originated when it
started to look like a lot of EE messages were about the AVR.
For now, MSP users should feel to use [EE], and if the volume
warrants it, we can consider a separate tag.  (IIRC, at the time
the AVR tag was created, there were few other forums for AVR
discussion.  Now there are, and there are also some active 430
mailing lists (like the one at yahoo.))

We're listening - but it just comes down to lack of time to participate
much.
Our own forums are quite popular and it takes time to manage that,
especially with
several hundred new people subscribing per month. Additionally, we make
15+ compilers for other architectures which also need attention.
