Atmel AT91SAM7S and AT91SAM7A3

Hello,

I have several projects where I have the need for a microcontroller  and
I considered to use 8051 compatibles but not it  is  not  more  possible
because I need an USBHID-PDU device interface,  which  can  only  solved
using Linux.

I like to use the AT91SAM7S and the AT91SAM7A3 (it has 16 AD-Converters)
and want to know, whether there is support for accessing the  8  and  16
AD-Converters directly via the Kernel.

Also I like to know, which memory size for the AT91 you recommend.

The current projects are:

1)  Solar-Volatge regulator
    (Uin <=68V, Uout=30V) with USB interface to PC or Master controller)

2)  24V PbGel charger
    (Uin=30V and nearly the same hardware as above)

3)  24V DV modular ATX PSU
    (special for solarsystems and must support minimal features of an
    UPS to protect the computer)

Q:  I have downloaded nearly all stuff about  specifications  to  USBHID
    and like to know, whether someone can point me to sample  codes  HOW
    to code the device stuff...  which seems currently not availlable in
    the Kernel...  (It seems, I am the first one WHO  need  this  stuff,
    but I am not a genie in C programming)

Note: "eCosCentric" sell USB stacks,  but  for  an  inacceptable  price, 
      since I build only small quantities for my projects.

Thanks, Greetings and nice Day/Evening

I would recommend posting this to a forum at http://www.at91.com.  This
is a list more for discussion of embedded issues in the kernel than SoC
end-user support :-)

I was already on <http://www.at91.com/> but where  I  live,  I  can  not
access the Web-Forum.  I need a mailinglist.

Also I realy do not knoe whether accessing the AD-Converters in a Micro-
controller is a user space issue or a Kernel one, since  I  need  Kernel
modules or not?

I realy do not know, how to begin this stuff...
