Eth_Set_Inport
Prototype
unsigned short Eth_Inport(unsigned short address);
Returns One byte from the specified address.
Description Retrieves a byte from the specified address of the Ethernet card chip.
Requires The card (NIC) must be properly initialized. See
Example
udp_length |= Eth_Inport(NIC_DATA);
Eth_Scan_For_Event
Prototype
unsigned Eth_Scan_For_Event(unsigned short *next_ptr);
Returns Type of the ethernet packet received. Two types are distinguished:
address data request) and
Description Retrieves sender's MAC (hardware) address and type of the packet received. The
function argument is an (internal) pointer to the next data packet in RTL8019's buffer,
and is of no particular importance to the end user.
Requires The card (NIC) must be properly initialized. See
called in a proper sequence, i.e. right after the card init, and IP address/UDP port init.
Example
Eth_Init(&PORTB, &PORTD, &PORTE, 2, 1, 0);
Eth_Set_Ip_Address(192u, 168u, 20u, 25u);
Eth_Set_Udp_Port(10001);
