'[EE] Interest levels in various uC's'

This is interesting:

www.google.com/trends?q=microchip+pic%2C+msp430%2C+h8%2C+ez80+%2C+atm
el+avr&ctab=0&geo=all&date=2007&sort=0

The Atmel AVR seems to be the only one that is gaining interest. If you
change it to look at all years, you can see this is a long term trend. All
search volume is dropping in this area.

Are there others that we should look at?

What is the current "hot" uC in terms of what the common man is interested
in learning about?

If by "common man" you mean anyone not doing a commercial design with
production run cost the overriding factor in uC choice, I'm not
surprised.  The hobbyist world, in particular, has more or less
abandoned microchip for AVRs, and for good reason.  Until very recently
there hasn't been a free C compiler for PICs (18F anyway), and microchip
has chosen to keep their debugging interface on the 18F series
undocumented.  This means no open-source, low-cost tools for doing
anything besides programming the chip.  I don't know if this will have a
material impact long-term, but anyone who asks me for advice about
microcontrollers (this would be the relatively inexperienced asking) I
tell them to go AVR and not PIC.

Am I looking at the same chart as you? When I open the link you posted, I
see the Atmel having the lowest level of the four, and while it seems to
have caught up with Microchip interest levels during 2006, I don't see it
gaining any more.

As Jesse says, I think the trend for the "common man" is towards open
source tools and documented interfaces.

I'm ordering a AVR ISP2 programmer right now actually... I've run into
too many problems with the limited number of PIC programmers that work
on Linux and the fact that there are 4 competing programs on Debian that
say they program AVR's, each of which supports about a dozen different
programmer models, is very encouraging for me. I also like that AVR's
JTAG debuggers are supported by open-source software, and people have
even figured out how to make other JTAG programmers program AVR's, even
non JTAG models. Choice is good.

Which is also why I'm ordering a PICkit2 to see if it'll avoid a
maddening bug I've found with my Olimex PICStart clone. Basically I have
a firmware that when burned into a 16lf819 *nothing* can reprogram it,
read it, erase it, ICSP or not. PGM is pulled low and code protection
is off.

Apparently the keywords selection puts Microchip PIC and Atmel AVR in
a disadvantaged position.

The more appropriate trend is like the following (to put the vendor
name in front
of the MCU family). Then you will see that Microchip PIC is on top, Atmel
AVR is the second and the other three disappear in the chart!

Of course. Arm7 and other ARM based MCU are hot.

ARM based MCU.

I think Google is losing volume. According to this link both windows and
linux are losing interest:

Just the end of the line... The current trend seems to be an increase in
interest in the AVR.

I was looking more at the change over time, and not to see which was on top.
Interest over time rather than absolute interest.

But you are looking at 2006 only. For 2007, in the last few months, the
trend is for the AVR to gain interest, and the others too loose.

This line looks way too noisy to me to make any conclusions from what I can
see in 2007. There seems to be somewhat an upwards trend in AVRs, but so
there seems to be one in PICs.

Also, the doubts about Google Trend I mentioned in another email apply here
also: Check out the top 10 regions; the USA is not even among them, nor are
most others of the main countries with electronic development. I'm not sure
a "trend" apparently carried mainly by Slovenia and the Czech Republic is
that relevant. (Nothing against these countries, but they are hardly
representative for trends in the electronics industry in the USA, NAFTA,
the Americas or the world.)

Either I don't understand the shown results, or they are really strange.

I suspect you can think of google trends as being in "beta", with
perhaps
some kinks to work out.  The strangeness reported is (IMO) more likely
to
be an issue with "google trends" than an actual indication of trends,
especially in obscure areas like microcontrollers.

I would generally expect particularly popular targets (especially in
obscure
areas) to spawn their own special sites; piclist.com, avrfreaks.net,
etc...

It is tough to interpret the results.

On explanation may be the effectiveness that some companies
communicate directly with their customers.

Another is how much do some companies depend on wide spread
general comments for marketing communication. Traditionally
part of Microchips approach compared to quiet communication to a few
high volume customers (Some of the better Taiwan companies)

Someone earlier pointed out the format of the question significantly
changed the results. I did another google exercise by asking the
same question and just looking for hits. Here the objective is to
see long term the body of literature that has accumulated

6502 applications
8051 applications
avr applications
pic applications

The above list is ordered by number of hits. Changing applications to
some other phrase is likely to yield other mixes.

What the google trends does show is the effect of a press announcement
on the number of hits but I don't think it extends to be a market predictor

It seems to me that we all interpret a lot into these Google Trend charts
without having a clue (at least I don't) what they really show. They almost
certainly don't show actual search numbers and their development.

Does anybody know what these charts show, how the numbers are calculated?

Totally ignoring the google trend, personally this list is virtually the
only involvement I have with PICs now - have almost completely gone over to
AVR having finally been forced to use one for a certain project, and found
it far easier to develop for.
