sub procedure Spi_Ethernet_putConstBytes(const ptr as ^byte, dim
n 

as byte)

Nothing.

This is MAC module routine. It stores requested number of const bytes into

ENC28J60

RAM starting from current 

ENC28J60

write pointer (

EWRPT

) location.

Parameters:

- 

ptr:

const buffer containing bytes to be written into 

ENC28J60

RAM. 

- 

n:

number of bytes to be written. 

Ethernet module has to be initialized. See Spi_Ethernet_Init.

buffer 

as byte[17]

...
buffer = "mikroElektronika"

...
Spi_Ethernet_putConstBytes(buffer, 16) ' put a const array into

ENC28J60 buffer

sub function Spi_Ethernet_putString(dim ptr as ^byte) as word

Number of bytes written into 

ENC28J60

RAM.

This is MAC module routine. It stores whole string (excluding null termination) into

ENC28J60

RAM starting from current 

ENC28J60

write pointer (

EWRPT

) location.

Parameters:

- 

ptr:

string to be written into ENC28J60 RAM. 

Ethernet module has to be initialized. See Spi_Ethernet_Init.

buffer 

as string[16]
