Otherwise you can get AT91SAM7X samples for free by talking
to your local friendly FAE...
www.freertos.org will provide you with RTOS + TCP/IP stack

Get each person in the group to start on each of the 3 choices, and
then after ~1 week, compare notes and tool flows. If it's looking
smooth, you can even implement this more than one way (as much of the
code will be common) then you have a great write-up, having solved it
more than once !

Using an FPGA to implement the TCP/IP stack seems a touch overkill for a
weather station.
Actually I would have though running ethernet to a weather station was a
touch iffy, although I supose you might use a wireless link. Even then
I would have though a simpler interface to a more powerful base station
made more sense. But it is a course assignment so the goals probably
don't match normal peoduct requirements.

You can use the "Gigabit" ethernet core in the Virtex IV FPGA chip
from the xilinx company.
But still you should realize the "TCP/IP" stack in the FPGA.

It's all been done before and readily available, so it could be done in 2
hours - not 2 months - aside of course from your weather station
interface... it all depends on what parts you are going to want to do
yourself...

i have to build a weather station. the data from the sensors is to be
transmitted via ethernet and IP protocols..
i couldnt really reach a decision on which of these develpoment tools
should i use.. or which one is better..?
1. FPGA
2. PIC18F + EN28J60+eeprom ( all from microchip)
3. microntroller with built in ethernet controller
OPTION1:
its a college project, so FPGA's are readily available and FREE.
but can we build a web server with TCP/IP stack and a ethernet
controller in FPGA within 2 months?
i would be glad if any1 told me that they have iimplemented a web
server in FPGA within2 months..
OPTION2: AND OPTION 3:
the PIC choice seems good but why spend time wiring PIC +EN28J60 when
u can find a microcontroller that already has a built in ethernet
controller..?there already is a TCP/IP stack written for PIC's though.
i need advice on time, money , and the possibilty of achieving the
goal in FPGA within 2 months .there are 3 ppl in my group including
me..
