406
mikoPascal PRO for PIC32
MikroElektronika
Parameters - mac: RAM buffer containing valid MAC address.
- ip: RAM buffer containing valid IP address.
- fullDuplex: ethernet duplex mode switch. Valid values: 0 (half duplex mode) and 1 (full duplex
mode).
Returns Nothing.
Requires Global variables:
- SPI_Ethernet_CS: Chip Select line
- SPI_Ethernet_CS_Direction: Direction of the Chip Select pin
- SPI_Ethernet_RST: Reset line
- SPI_Ethernet_RST_Direction: Direction of the Reset pin
must be dened before using this function.
The SPI module needs to be initialized. See the SPIx_Init and SPIx_Init_Advanced routines.
Example
// SPI Ethernet module connections
var SPI_Ethernet_RST : sbit at RF0_bit;
var SPI_Ethernet_CS : sbit at RF1_bit;
var SPI_Ethernet_RST_Direction : sbit at TRISF0_bit;
var SPI_Ethernet_CS_Direction : sbit at TRISF1_bit;
const SPI_Ethernet_HALFDUPLEX = 0;
const SPI_Ethernet_FULLDUPLEX = 1;
var
myMacAddr : array[6] of byte; // my MAC address
myIpAddr : array[4] of byte; // my IP addr
