How to connect Arduino Ethernet to USB Adapter?

I just got the new Arduino Ethernet, and Mini USB adapter. There isn't a cable or any documentation on how to connect the two to program the Arduino, and they don't seem to plug together.

Can anyone point me in the right direction?

After that I'll be looking to build a web interface to display message on a 4x20 LCD display so any info on that (and sample code) would be great too!

Thanks in advance.

Thanks for your reply, I hope this post clarifies what I’m trying to do.

  1. Arduino Ethernet is this one:

  2. USB/Serial Converter is this one:
    http://store.arduino.cc/eu/index.php?main_page=product_info&cPath=11_15&products_id=86

I would like to program item 1 from my Windows laptop using item 2 as the interface between the laptop and item 1.
I can connect item 2 to the laptop using a USB cable, but don’t know how to connect item 2 to item 1.

Indeed. The description for the Arduino Ethernet says: "A six pin header can be connected to an FTDI cable or USB Serial board to provide USB power and communication to the board. "

So when ordering I expected this to be plug and play (I've previously used other AVR based Ethernet boards that were more straightforward to get started with). As it's not, it would be nice to at least have some simple instructions on how to connect them. There was nothing supplied with them and doesn't appear to be any official or unofficial info online.

Can anyone provide such instructions? I'm a programmer with only very basic electronics skills. :~

Would this AVR programmer work? http://shop.tuxgraphics.org/electronic/detail_avrusb500smd2.html

I got the wrong end of the stick too. So Ignore the post I just removed.....

Item 2 is entirely un-related to Item 1. What you need to program Item 1 is an ISP which is available in numerous forms or can be made from a standard Arduino (Uno/Duemilanove/Mega) with a ISP sketch loaded.

This should do the trick : http://cgi.ebay.com/USBtinyISP-AVR-ISP-Programmer-Arduino-bootloader-/320718303954?pt=LH_DefaultDomain_0&hash=item4aac4cf2d2

You'll need to tweak the Arduino software to directly program with it.

Ouch! That's a bit expensive for an AVR programmer (an "ISP"). You can buy a second board and follow the ArduinoISP instructions to turn it into an ISP.

Would this AVR programmer work?

Yes but in a dramatically different way. There are pros and cons to each method.

Pluggy, this is taken from the link to item 1 above: "The Arduino Ethernet is a microcontroller board based on the Arduino Uno, and incorporating a WizNet W5100 TCP/IP Embedded Ethernet Controller. It can be programmed like an Uno via a six-pin FTDI -style serial connector. The Arduino USB-to-Serial adapter or any FTDI-style USB-to-serial connector can be used to program it. "

This is what I bought based on what the website says, I don't wish to bin it and buy something else! Is the web-site misleading?

Perhaps this is the correct item for programming? http://store.arduino.cc/eu/index.php?main_page=product_info&products_id=143 Confusingly it's listed under boards rather than accessories.

The USB/Serial Converter I purchased is under accessories.

It's not made clear :(

I thought I was avoiding all of the clone issue buy buying "original" products from the official Arduino store. The descriptions on the store should be much clearer, and should link to related products as there are similarly named products. All in all a very poor first experience with Arduino.

The description specifically refers to "Arduino USB-to-Serial adapter" which sounds like an accessory not another board, how was I to know it wasn't the "USB/Serial Converter" accessory but the "USB 2 Serial Converter" board. :(

KE7GKP: Yes, that "USB 2 Serial Converter" looks like what was intended for that board.

I completely agree that the marketing (organization, illustration, examples, documentation, even the names) of Arduino products, clones and accessories is generally a mess. Part of that is just what we can expect from an open-source marketplace where people are free to do whatever they wish.

But particularly galling are the relatively sophisticated and inexpensive items (boards, etc.) for which there is NO technical documentation whatsoever. They seem to be sold by people who don't know an Arduino from an artichoke. Several of the Asian vendors are the worst offenders in this respect.

Update:

The guys at Arduino Store reacted very quickly to fix this issue. They have linked the correct product in Arduino Ethernet product page and sent me the correct item by UPS at no charge.

I've now been able to successfully upload the blink program to my Arduino Ethernet (changing the output pin from 13 to 9).

Thanks for all of the replies.

Hi guys.

I bought this cable instead : http://www.sparkfun.com/products/9718

I can't upload any sketches to my Arduino Ethernet board. Is the cable the problem? Should I get the USB 2 Serial Converter?

Thank you.

What exactly happens when you try to upload the sketch?

Do you see the power light on the Arduino Ethernet when the cable is connected? Does the COM port appear in Device Manager? Does the Arduino software give you any error messages when you try to upload? What sketch are you trying to upload? I suggest trying blink with the PIN change I mentioned above as it's a very simple one.

Yes.
Yes.
Yes, these are the errors I get:
avrdude: stk500_getsync(): not in sync: resp=0x00
avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x51

I tried any sketch and all the time I get the error above.
