<< Architecture of\u00a0the Ethernet board >><\/p>\n

The\u00a0Ethernet module, WIZ820io, is connected with the microcontroller, PIC18F27J53,\u00a0using the Serial Peripheral Interface (SPI).<\/p>\n

Clock and pin connection of PIC18F27J53 :<\/p>\n

The system clock of 48MHz\u00a0is derived from the external ceramic resonator of 4MHz using the PLL module.<\/p>\n

(Compiled by\u00a0the C18 under\u00a0the large code model\u00a0on the\u00a0MPLAB X IDE)<\/p>\n

In TCPIPConfig.h, STACK_USE_DHCP_CLIENT, STACK_USE_NBNS and STACK_USE_TCP\u00a0have been\u00a0defined in this project.\u00a0 Consequently, the test board can practice the communications-protocol of DHCP Client and NBNS.<\/p>\n

The default network configuration in TCPIPConfig.h\u00a0must be adjusted to your local network (MAC address, IP\u00a0address and so on).<\/p>\n

Example above:
\nNetBIOS Name = PIC18F27J53
\nDefault MAC address = {0x00, 0x04, 0xA3, 0x00, 0x00, 0x00}
\nDefault IP address\u00a0 = 192.168.1.10
\nDefault subnet mast = 255.255.255.0
\nDefault primary DNS = 192.168.1.1
\nDefault secondary DNS = 0.0.0.0<\/p>\n

The connection to the Ethernet board can be checked by the ping on the Command Prompt of your Windows PC.<\/p>\n
