Detailed Description

Configuration options for uIP.

This file is used for tweaking various configuration options for uIP. You should make a copy of this file into one of your project's directories instead of editing this example "uipopt.h" file that comes with the uIP distribution.

Definition in file uipopt.h.

Static configuration options
These configuration options can be used for setting the IP address settings statically, but only if UIP_FIXEDADDR is set to 1. The configuration options for a specific node includes IP address, netmask and default router as well as the Ethernet address. The netmask, default router and Ethernet address are appliciable only if uIP should be run over Ethernet. All of these should be changed to suit your project.
#define	UIP_FIXEDADDR
	Determines if uIP should use a fixed IP address or not.
#define	UIP_PINGADDRCONF
	Ping IP address asignment.
#define	UIP_FIXEDETHADDR
	Specifies if the uIP ARP module should be compiled with a fixed Ethernet MAC address or not.
IP configuration options
#define	UIP_TTL   64
	The IP TTL (time to live) of IP packets sent by uIP.
#define	UIP_REASSEMBLY
	Turn on support for IP packet reassembly.
#define	UIP_REASS_MAXAGE   40
	The maximum time an IP fragment should wait in the reassembly buffer before it is dropped.
UDP configuration options
#define	UIP_UDP
	Toggles wether UDP support should be compiled in or not.
#define	UIP_UDP_CHECKSUMS
	Toggles if UDP checksums should be used or not.
#define	UIP_UDP_CONNS
	The maximum amount of concurrent UDP connections.
TCP configuration options
#define	UIP_ACTIVE_OPEN
	Determines if support for opening connections from uIP should be compiled in.
#define	UIP_CONNS
	The maximum number of simultaneously open TCP connections.
#define	UIP_LISTENPORTS
	The maximum number of simultaneously listening TCP ports.
#define	UIP_URGDATA
	Determines if support for TCP urgent data notification should be compiled in.
#define	UIP_RTO   3
	The initial retransmission timeout counted in timer pulses.
#define	UIP_MAXRTX   8
	The maximum number of times a segment should be retransmitted before the connection should be aborted.
#define	UIP_MAXSYNRTX   5
	The maximum number of times a SYN segment should be retransmitted before a connection request should be deemed to have been unsuccessful.
#define	UIP_TCP_MSS   (UIP_BUFSIZE - UIP_LLH_LEN - UIP_TCPIP_HLEN)
	The TCP maximum segment size.
#define	UIP_RECEIVE_WINDOW
	The size of the advertised receiver's window.
#define	UIP_TIME_WAIT_TIMEOUT   120
	How long a connection should stay in the TIME_WAIT state.
ARP configuration options
#define	UIP_ARPTAB_SIZE
	The size of the ARP table.
#define	UIP_ARP_MAXAGE   120
	The maxium age of ARP table entries measured in 10ths of seconds.
General configuration options
#define	UIP_BUFSIZE
	The size of the uIP packet buffer.
#define	UIP_STATISTICS
	Determines if statistics support should be compiled in.
#define	UIP_LOGGING
	Determines if logging of certain events should be compiled in.
#define	UIP_BROADCAST
	Broadcast support.
#define	UIP_LLH_LEN
	The link level header length.
void	uip_log (char *msg)
	Print out a uIP log message.
CPU architecture configuration
The CPU architecture configuration is where the endianess of the CPU on which uIP is to be run is specified. Most CPUs today are little endian, and the most notable exception are the Motorolas which are big endian. The BYTE_ORDER macro should be changed to reflect the CPU architecture on which uIP is to be run.
#define	UIP_BYTE_ORDER
	The byte order of the CPU architecture on which uIP is to be run.
Defines
#define	UIP_LITTLE_ENDIAN   3412
#define	UIP_BIG_ENDIAN   1234
