Connecting the ENC28J60+PIC18F4620 boad to a router

Hi,

I am currently testing my board to connect to the router in my house to test whether it can be accessed by other computers. But i am facing problems on how to get the board connected? It is just connect it through cable or i need to configure the router? I have include HTTP,ARP, ICMP, and TCP in the board. The IP assigned was 192.168.0.x which is for the local network. Am i missing something??

A router isn't involved in local network communication, except for a possible DHCP function, which is apparently not used due to fixed IP configuration. The PIC host should answer ARP and PING requests without additional software running. To establish ingoing TCP connections, a server application must be present at the PIC.

Hi FvM,

I not really understand about it. Is it means that inside the PIC there should be a HTTP server to respond request from others?

You didn't tell about your intended kind of operation. For a HTTP connection, yes you need a HTTP server. CCS has provided examples for it.

Hi,
i have tested the board with different cable, cross and straight cable connecting to the router... but i cant detect the board from the router. Which i attend to have a local network communication with the board

Yes, I also understood local network. So the router is only working as a switch or hub, depending on the hardware. As a first step, you shouldn't replace cables but check the link status of both peers. An established ethernet link is the elementary prerequisite for any communication. Then I would start monitoring the communication with a network monitor as Wireshark. If you are connecting through a switch, most of the communications won't be propagated to other ports, so it's most simple to connect from a PC that is running also the monitor. If you perform a ping, you should see ARP and ICMP packets.

If you get no answer at all, check hard- and software at the PIC side and trace respective network actions with a debugger.

Hi,

I finally get my board connected to my house's router! I was provided with another cross cable by my lecturer, and i just tried it out! The board now response to ping and arp as well. Thank god. By the way, yesterday i was testing with a hub and not a router (now only i differentiate it). Anyway, thank you guys for giving me the info.
