Please help with my erhernet board project

[tonyyy]

Hi.
I need to create a small board with ethernet capabilities. The goal of the board
is to forwading data to a remote server using PIC18XX via http. Here my doubts:

- What ethernet controller? ENC28j60,TL8019AS,CS8900A-CQ,w5100...
- the board is acutally an http client pushing data using rest with both get and post (json format). Is not necessary to send values in real time.
- Assuming the inputs are just three analog signals (i.e. t1,t2,t3) I am thinking to
generate an interrupt when data is ready and save it in a memory locations.
- Another "process" will then regularly read the memory assemble the http request and
actually send it.

Should I use embedded multitasking on a a single PIC? Shoud I use two pics one for gathering data and the second for sending it?


Thanks in advance

Firstly have you downloaded the Microchip TCP/IP Stack? This should get you up and running and I suggest you use a PHY that is already supported, or is electrically identical. You should only use one PIC for this.

If you use mikroC Compiler it is very easy. mikroE also has ethernet add on boards. Check their ethernet examples at libstock.com

Hello, my project name is Serial Ethernet Board- communication between PC and MCU trough Ethernet and ENC28J60 but I don't know how to start it. I have to write code in MikroC so if anyone can help me or send mi some code it would be great
