Prototype void Eth_Init(char *addrP, char *dataP, char *ctrlP,
char pinReset, char pinIOW, char pinIOR);
Description 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.
Requires As specified for the entire library (please see top of this page).
Example Eth_Init(&PORTB, &PORTD, &PORTE, 2, 1, 0);
Eth_Init
Prototype void Eth_Set_Ip_Address(char ip1, char ip2, char ip3, char ip4);
Description 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).
Requires 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.
Example // Set IP address 192.168.20.25
Eth_Set_Ip_Address(192u, 168u, 20u, 25u);
