simple mode to send UDP packet ?
PostPosted: Wed Sep 16, 2009 10:19 am     Reply with quote
hi,
i need to send UDP packets to a single TCP/IP address in a local network.
ONLY SEND, ONLY UDP, ONLY single address, ONLY local network.

do you know a SIMPLE code to obtain this, using the PIC with controller ethernet inside ? (PIC18 "J" series ?)

i cant use the "serial-ethernet" modules, like tibbo or lantronics ....

thanks in advance

have you looked at the CCS code yet? You'll need to set up the ethernet module one way or another...

Once you learn the TCP/IP code, doing UDP is pretty easy....

If you use a light weight PIC18F family member then RFC1149 outlines the simplest method. http://www.faqs.org/rfcs/rfc1149.html
