Eth_Init(char *addrP, char *dataP, char *ctrlP,

pinReset, char pinIOW, char pinIOR);

Performs initialization of Ethernet card and library. This includes:
- Setting of control and data ports;
- Initialization of the Ethernet card (also called the Network Interface Card, or NIC);
- Retrieval and local storage of the NIC’s hardware (MAC) address;
- Putting the NIC into the LISTEN mode.

Parameter 

addrP

is a pointer to address port, which handles the addressing lines.

Parameter 

dataP

is pointer to data port. Parameter 

ctrlP

is the control port. Parameter

pinReset

is the reset/enable pin for the ethernet card chip (on control port). Parameter

pinIOW

is the I/O Write request control pin. Parameter 

pinIOR

is the I/O read request

control pin.

As specified for the entire library (please see top of this page).

Eth_Init(&PORTB, &PORTD, &PORTE, 2, 1, 0);

Eth_Set_Ip_Address(char ip1, char ip2, char ip3, char ip4);

Sets the IP address of the connected and initialized Ethernet network card. The
arguments are the IP address numbers, in IPv4 format (e.g. 127.0.0.1). 

This function should be called immediately after the NIC initialization (see 

Eth_Init

).

You can change your IP address at any time, anywhere in the code.

// Set IP address 192.168.20.25

Eth_Set_Ip_Address(192u, 168u, 20u, 25u);
