procedure Spi_Ethernet_putConstBytes(const ptr : ^byte; n : 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 : 

array[17] of byte;

...
buffer := 'mikroElektronika';
...

Spi_Ethernet_putConstBytes(buffer, 16); // put a const array

into ENC28J60 buffer

function Spi_Ethernet_putString(^ptr : byte) : 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 : 

string[16];

...
buffer := 'mikroElektronika';
...

Spi_Ethernet_putString(buffer); // put a RAM string into

ENC28J60 buffer
