Thank you for the warning on the header. I was starting to kick ideas around in my head regarding my design because I also signed up and am looking forward to developing something for the contest. I hope they ship the item to me in Hong Kong!
I briefly glanced at the datasheet. It looks like there are three different hardware ways to connect to the chip. I imagine most will probably use the SPI because it consumes the least amount of pins and SPI drivers are easy. Is any one considering the direct bus interface moderequiring 27 I/O lines or the indirect bus interface mode requiring 14 I/O lines?
One project possibility I had would require the highest throughput I could get, but consuming 27 I/O lines doesn't leave me any room for the hardware so I may go the indirect bus interface mode.

Delivery needed 7 days, but from US to Germany.
You get a confirmation mail, if the Module is shiped :
Hello,
This e-mail confirms that your request for the WIZnet iEthernet Design Contest sample has been approved. All shipments are being sent via USPS for both Domestic and International shipments. Please allow 2-3 weeks for delivery.
The WIZ810MJ is a network module that carries the W5100 (TCP/IP hardwired chip, includes PHY) and MAG-JACK (RJ-45 with X’FMR) with other glue logics. It can be used as a component and no effort is required to interface the W5100 and Transformer. The WIZ810MJ is an ideal option for users who want to develop their Internet-enabling systems rapidly.
For more detailed information about the WIZ810MJ and the eligible contest part (the W5100), please review the datasheets that can be found at www.wiznet.co.kr/. You will also find the W5100 porting guide at the WIZnet site.
You are welcome to physically use the WIZ810MJ as part of your project submission or you can make your own printed circuit board that includes the W5100. (The W5100 chip is the only required contest device. You may use any other MCU or peripheral device in addition to the W5100.) You may also use other WIZnet boards that include the W5100. These may be purchased through www.ewiznet.com/.

Contest Benefits
We know it takes a lot of hard work to put together a design contest entry, but the rewards are definitely worth the effort. The excitement of working with this evaluation kit is just one of the many benefits. Your design could win you a share of $15,000 in cash prizes. The top designer in this contest will walk away with $5,000.
We’ve received a lot of feedback over the years, and what we’ve learned from administering numerous design contests is that public recognition is probably the best reward for entering a contest. Winning a prize certainly has its financial perk, but having your project selected by us for posting is an honor that keeps on giving. Industry leaders pay attention to these contests. We’re proud to say that a considerable number of past contest entrants report that the publicity from their participation had a great deal of positive benefit for both their careers and their manufacturing ambitions.
And if you needed any more inspiration, remember that we’re always looking for fresh editorial content and our real job is publishing an engineering magazine focused on embedded applications. We know good work when we see it so you can expect that we will ask a number of entrants to convert their entries into articles. If you’d like to see your name in print, keep thinking that this isn’t just a contest—it’s an opportunity!
I think in most cases SPI will do the job.
If you need high throughoutput, the Bus interface is needed, eating up all your I/O pins :-(
But as you dont have to care about the network stack, it leaves you nearly all memory resources for your
application. This could be the perfect deal to get tcp/ip to the Propeller.

I'd love to have one, but I really don't have a contest entry.
I imagine that living in Asia, Mumbai, Singapore,Taiwan, Tokyo, or Hong Kong might actually give you a better chance of getting one. They really want to reach a pool of working engineers.
Since I'm just a hobbyist, I'll pass. The goodies are getting smaller and smaller, aren't they.

You dont need to have a contest entry to get a sample kit.
The contest ends in 4 months, so enought time to get an idea, or not.
This is a contest also for hobbyists, as many also do something similar at
their job, its the perfect target group to get involved.
Well the form sure works, I got the hardware in yesterday, I also got the acceptance e-mail. Now I just have to find a good way around this 2mm problem, how I love the smell of ferric chloride.
Oldbitcollector,
The file"WIZ810MJ " on the page provide by the link above shows the pin out. The Data sheet for just the W5100 chip(found at the WizNet Web site) shows the registers and methods for operation of the module.
Hope this helps.
If any finds out what to do with unused pins let me know! ie: using serial, the bus pins are tied to what?
Opps,
Sorry Oldbitcollector,
Just noticed you were referring to the 2mm spacing. Totally understand that!

I got my parts the other day here in Hong Kong. I am excited to see what others come up with using this chip. I have one idea cooking already and I started to lay down some code for a driver. I am torn between the indirect connection method and the SPI method.
Bambino - There was a link in the "device shiping e-mail" (I think) to a Circuit Cellar article by Fred Eady. He made his own board and placed a chip on it. He.....
Opps scratch that thought, he connected every pin to the PIC he was using. I will let you know if I find something related to unused pins as I read through the datasheet and get experimenting. For now I was planning on wire wrapping to the SPI pins to get the device working and leave the other pins blank (expect for ground/power/and those pins called out to be high or low)

That is exactly what I am up to(SPI), I am just going to leave them floating for now. I have a demo board from another micro... product modified for use with a Propeller and it has a proto area with 2mm spacing.(never thought I would use it for anything)

The Module looks very nice, but uses 2mm pinheaders.

What a mess.. I have no idea how I would hook to these pins to get started...

Hey oldbitcollector, would the small pin headers we saw at philcap be of any use. Only trying to add my two cents.
Post Edited (TheWizard65) : 10/22/2007 10:58:15 PM GMT
That does it! Contest just isn't worth it now! Gonna remove the MagJack and put it on a 2nd PropNIC.
