mikoC PRO for PIC32

MikroElektronika

Library Example

This code shows how to use the Ethernet mini library:

- the board will reply to ARP & ICMP echo requests

- the board will reply to UDP requests on any port:

- returns the request in upper char with a header made of remote host IP & port number

- the board will reply to HTTP requests on port 80, GET method with pathnames:

- / will return the HTML main page

- /s will return board status as text string

- /t0 ... /t7 will toggle RD0 to RD7 bit and return HTML main page

- all other requests return also HTML main page.
