AVR-Chat

Excellent!  Thanks Larry :)

Welp, here we go folks.  I have 20 Atmel ATmeg64-16AI chips sitting here
with more on the way.  Our board is the tightest I've ever worked on.
Some chips are as small as 3mm x 3mm and yup, I get to solder them all
(joy?).  The board gerbers will be sent out within 10 days and another 7
to 9 day turnaround including shipping (using www.4pcb.com unless
someone has a better company (cheaper) although I'm getting 24 boards
for about $170 including shipping).

I won't have a lot of time for other activities over the next couple two
or three months and now I'm starting the software design cycle so I'll
have lots of questions including this one:

So like um...  using the SPI interface connected to a port will allow me
to upload the program to flash.  This is an automatic thing right?  I
mean, there is no boot loader program needed?  And this always works,
meaning, there isn't any chance of wiping some memory or register where
this upload process will stop working?

So, really SPI is it right? :)

Please understand that I'm old :P  Actually my point is I come from the
days of the 6800, 8085, and 8088.  These new fangled chips rock the
earth when it comes to peripherals.  Even though I have lots of current
experience I still find some of the newer technology almost
unbelievable.  And I have a lot of silly questions sometimes.

Perhaps the government does have some kind of deal with the aliens.

All mega chips have the brownout circuitry integrated into the chips.

When you say "You can dispense with the reset chip" do you mean just for
the purposes of learning or is brownout detection already integrated on
the CPU?

Are there any external supervisory circuits needed?
