(TCP\/IP protocols are included in the application code for the PIC24FJ256GB106.)<\/p>\n\n\n\n

<< Architecture of the Ethernet board >>
The Ethernet controller, ENC28J60, is connected with the microcontroller, PIC24FJ256GB106, using the Serial Peripheral Interface (SPI).<\/p>\n\n\n\n

Clock and pin connection of PIC24FJ256GB106 : The system clock of 48MHz is derived from the internal oscillator of 8MHz using the PLL module.<\/p>\n\n\n\n

LED : pin 2 (RE6), pin 3 (RE7).
Switch (pull down) : pin 7 (MCLR), pin 8 (RG9).<\/p>\n\n\n\n

Pin 6 SO  \u2013-  PIC pin 31 (RP10\/RF4 assigned to SDI1),
Pin 7 SI  \u2013-  PIC pin 32 (RP17\/RF5 assigned to SDO1),
Pin 8 SCK  \u2013-  PIC pin 33 (RP16\/RE3 assigned to SCK1),
Pin 9 CS  \u2013-  PIC pin 58 (RF0),
Pin 10 RESET  \u2013-  Open (Internally pulled-up to VDD).<\/p>\n\n\n\n

(Compiled by the XC16 on the MPLAB X IDE)<\/p>\n\n\n\n

In TCPIP ENC28.h, STACK_USE_ICMP_SERVER, STACK_USE_DHCP_CLIENT and STACK_USE_NBNS have been defined in this project. Consequently, the test board can practice the communications-protocol of ICMP, ARP, DHCP Client and NBNS.<\/p>\n\n\n\n

The default network configuration in TCPIP ENC28.h must be adjusted to your local network (MAC address, IP address and so on).<\/p>\n\n\n\n

Example above :
NetBIOS Name = PIC24FJ256GB106
Default MAC address = {0x00, 0x04, 0xA3, 0x00, 0x00, 0x00}
Default IP address = 192.168.1.10
Default subnet mast = 255.255.255.0
Default gateway = 192.168.1.1
Default primary DNS = 192.168.1.1
Default secondary DNS = 0.0.0.0<\/p>\n\n\n\n

The connection to the Ethernet board can be checked by the ping on the Command Prompt of your Windows PC. And if the connection has been established, the test page can be viewed by a web-browser on your computer.<\/p>\n\n\n\n
