Ethernet Confusion Pic Web Server Question

[HenrikOlsson]

Hi Shawn,
Yes, I'm still working on it but not so frequent. The AMICUS18/Ethernet shield served well as an initial development platform but I've since designed my own board so I have the intention of continuing the project. The basic idea was, like the title says, some kind of collaboration but the interest seemed pretty low, it would be cool if you jumped in!

As you know the Ethernet shield contains a SD-card holder but on my own board I opted for a serial FLASH memory (SPI) instead. The problem/issue/hurdle is to handle the "filesystem", I mean it's probabaly not going to take much to get the current example going with external memory but you want to be able to download more advanced pages with multiple files etc, from the PC to the memory. I haven't given it enough thought yet.

Like I said, if you're interested please do jump in!

I have no experience in such designs but I jump in to help if I can and learn too...

Can you squeze the graphics more and have less memory requirements, so that a Tibbo or other similar device be used?

Ok, I'm just about onboard with the PIC/W5100 setup. I'm still kicking around the thought of using the ENC28J60 chip. To me right now I'm thinking the only main difference is that the ENC28J60 doesn't do stack and the pic will have to handle it. That is a disadvantage because I don't really want to deal with the stack. And the W5100 will handle all stack and handshaking. I'm wondering what the disadvantage of using the W5100 is? Maybe the through put is not as good when using the ENC28J60. Both are spi devices so they should both work as fast as you can dump data to them.

Yes I am going to order some W5100 Monday.

I am going to jump on the band wagon. However I may trip and fall off.

Hi Shawn,
Yes, the W5100 handles the TCP/IP stack while on the ENC28J60 you'd have to code the stack (too) in PBP. For me, being an ethernet rookie, it was a given especially conciddering the small difference in price. One drawback is its bloody tiny.... 0.2mm legs on 0.4mm pitch.....

There's now a W5200 which is also an SPI device (unlike the W5300) but with 32k buffer and 8 simultaneous sockets. I've only looked at the datasheet brifely but it looks very simmilar to the W5100 commandwise.

Looking forward to hear about your adventures!
