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..
implementing ethernet server on FPGA or other choices

But still you should realize the "TCP/IP" stack in the FPGA.

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.

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 ! -jg
