Word search still shows a bunch of references to "Atmel":

12.4 EEPROM Data Memory
     The Atmel AVR ATmega8A contains 512 bytes of data EEPROM memory. It is organized as a separate
     data space, in which single bytes can be read and written. The EEPROM has an endurance of at least

and to "www.atmel.com/avr" which is redirected to microchip.

Ha ha, someone has been a bit too quick here :-) I will report this. Thanks for pointing this out.

I think there are far more important things that you should be reporting first; eg, 

 

http://www.avrfreaks.net/forum/stk600-documentation-has-been-cleaned

 

http://www.avrfreaks.net/forum/lots-brokenmissing-links-after-atmelcom-closed-redirect-microchipcom

 

http://www.avrfreaks.net/forum/where-flip-or-something-better

 

and that's before we even start on the forum bugs!

Just my luck. As soon as I find something worth considering or cherishing, there is some financial lune there and ripping it to pieces. How long will the megas survive before dermise ?

They will survive, only re-branded as a PIC.....Just Watch

Very likely no such lune in the Microchip front office.

The Great Recession ('07 brew, '08 flush) was a significant impact on most semiconductor manufacturers.

Am wondering why the axe hasn't yet again fell upon us; we're about two years overdue.

From Old Norse lugna (“to calm”)

That seems closer to home.

Confirmed.

 

1 verb "to calm down"

 

2. adjective, plur. "to be calm"

 

3. imperative "clam [e.g. yourself] down"

Well yes, two might though be an understatement. I should have refrained from sneering at MBA, and gone into ripping business instead for trying to create and build :)

(so ent1 was my intension)

 

Changing name of a boat or ship, is normally not a good idea, as superstition goes at least. In this case, unecessary intrusion to documentation is normally never a success since there is little motivation and low momentum for the task, leaving text in a more or less deteriorating and sad state. Its a bit like Rome; fun to build less fun to maintain, goes for a number of things actually.

 

with a tendency for unresonablility ;)

As to lugn/lugna yes that is quite correct; curiously it also evolves in Norwegian to rolig, meaning in Swedish funny.

 

Thx for Haglund! looks like I would possilby buy me a one-way to Seatle. But I guess I wouldnt afford a house, all bought by Chineese, eh?

lugna -- plural of lug nut.  In a sentence:  "After changing your wheel, ensure the lugna are tight."

 

Now I suppose I need to say something on topic.  But what can I say?  The new overlords have now made the venerable Mega8 into a PIC18.

You can put lipstick on a pig, but it is still a pig.

I've never met a pig I didn't like, as long as you have some salt and pepper.

Relative to MBA, a well experienced accountant said to me that it's USA business schools that have ruined us (via Wall Street?)

Wall Street may have been "sawed off" (its own sandbox) such that the rest of the world doesn't have to feel the pain; am a sceptic on that because it's all tied through BIS.

Maintenance can be a worthwhile effort IF there's management and director and executive support.

Have thought that AVR16 would be good but it would compete against PIC24.

Likely better to setup a third table and bring the best from the current two tables to create a new 16b MCU architecture.

Would compete well against MSP430 and go into slips that the arm juggernaut cannot (work strengths, shore weaknesses)

Very risky; less risk to share between the two tables.

16b MCU is a sweet spot in a greatly expanding embedded computer arena.

Unfortunate I havnt leveld to the 16bits, Im still glad for the stenght and simplicity and "enough but just enough" & straight forward mentality of the (Norwegian built as I have it) Atmegas.

But I guess that the paradigm of ever growing code will be very much in line with what I percieve  you say. But is it possible to make a simple-stupid just enough architecture anymore ?

 

But wasnt Stevie blind ?

Yes as in the 8051 follow-ons that compete against AVR (mega, XMEGA)

I just bought a hundred each MC9RS08KA8 and MC9S08QD4 (less than $0.10 each from Newark's "Overstock" list.  Perhaps because NXP is going to axe the old Motorola 8bit chips?)
They're pretty trivial.  One AC, one Index register, one SP, one 64k address space with everything in it.  Now I have enough "simple stupid" chips to last the rest of my life...

Again? They seems to have obliterated the fact that they used to make HC11 and HC05 chips......

"I Will Survive"  [as a 'Freak without Atmel AVR]
 

At first I was afraid, I was petrified,
Kept thinking I could never live without you by my side
But then I spent so many nights thinking how you did me wrong,
And I grew strong, and I learned how to get along.

And so you're back from outer space.
I just walked in to find you here with that sad look upon your face
I should have changed that stupid lock
I should have made you leave your key
If I had known for just one second you'd be back to bother me

Go on now, go. Walk out the door
Just turn around now 'cause you're not welcome anymore
Weren't you the one who tried to hurt me with goodbye?
Did you think I'd crumble?
Did you think I'd lay down and die?

Oh, no, not I!
I will survive.
Oh, as long as I know how to love I know I'll stay alive.
I've got all my life to live.
I've got all my love to give.
And I'll survive,
I will survive, hey, hey.

It took all the strength I had not to fall apart.
Kept trying hard to mend the pieces of my broken heart.
And I spent, oh, so many nights just feeling sorry for myself.
I used to cry but now I hold my head up high.

And you see me somebody new. [rebranded with new datasheets]
I'm not that chained-up little person still in love with you.
And so you felt like dropping in,
And just expect me to be free.
And now I'm saving all my loving for someone who's loving me.

[2x]
Go on now, go. Walk out the door.
Just turn around now 'cause you're not welcome anymore.
Weren't you the one who tried to break me with goodbye?
Did you think I'd crumble?
Did you think I'd lay down and die?
Oh, no, not I!
I will survive.

Oh, as long as I know how to love I know I'll stay alive.
I've got all my life to live.
I've got all my love to give.
And I'll survive,
I will survive.

As the lines lie now, it seems that only BIG industry is to survive. Entrepreourship, innovators, think-and-doers are doomed. It is HR, it is mega-projects, mega investments, dont bother with products that dont sell over 100M items, .... a guppy code that gets VC attention builds a brand and an equity of billions of bucks.

Don't be so negative, anyone can still create and market a product.

The whole "mega-funding" thing will one day go belly up, like it did in the dot.com era and 2007/2008. It's just the nature of economic cycles.
