CHAPTER 6

The following variables

must be defined in all

projects using SPI Eth-

ernet Library:

Description:

Example :

var SPI_Ethernet_CS :
sbit; sfr; external;

ENC28J60 chip select pin.

var SPI_Ethernet_CS :
sbit at PORTB.B4;

var SPI_Ethernet_RST :
sbit; sfr; external;

ENC28J60 reset pin.

var SPI_Ethernet_RST
:

sbit at PORTB.B5;

var
SPI_Ethernet_CS_Direc
tion :

sbit; sfr;

external;

Direction of the ENC28J60
chip select pin.

var
SPI_Ethernet_CS_Direc
tion :

sbit at

DDRB.B4;

var
SPI_Ethernet_RST_Dire

ction :

sbit; sfr;

external;

Direction of the ENC28J60
reset pin.

var
SPI_Ethernet_RST_Dire

ction :

sbit at

DDRB.B5;

The following routines must

be defined in all project

using SPI Ethernet Library:

Description:

Examples :

function
Spi_Ethernet_UserTCP(remo

teHost : ^byte,

remotePort : word,

localPort : word,

reqLength : word): word;

TCP request handler.
