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

The\u00a0Wi-Fi module, MRF24WG0MA, 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)<\/p>\n

In HWP PIC18EX_MRF24W.h, the WF_INT configuration has been changed from the INT0 in high priority to INT1 in low priority.<\/p>\n

In TCPIPConfig.h, STACK_USE_ICMP_SERVER, STACK_USE_DHCP_CLIENT and STACK_USE_NBNS\u00a0have been\u00a0defined in this project.\u00a0 Consequently, the test board can practice the communications-protocol of ICMP, ARP, 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

In WF_Config.h, the following parameters must be adjusted to your Wi-Fi network.<\/p>\n

#define MY_DEFAULT_NETWORK_TYPE\u00a0\u00a0\u00a0 *****
\n#define MY_DEFAULT_WIFI_SECURITY_MODE\u00a0\u00a0\u00a0 *****
\n#define MY_DEFAULT_SSID_NAME\u00a0\u00a0 \u00a0“******”
\n#define MY_DEFAULT_PSK_PHRASE\u00a0\u00a0\u00a0 “*****”
\n#define MY_DEFAULT_PSK\u00a0\u00a0\u00a0 “*****”<\/p>\n

The connection to the Ethernet board can be checked by the ping on the Command Prompt of your Windows PC.<\/p>\n","protected":false},"excerpt":{"rendered":"
