WiFi shield not present

I use Arduino Wifi Shield and upload example("ScanNetworks"), but Serial Monitor display ?WiFi shield not present?.

ScanNetworks code: http://arduino.cc/en/Tutorial/ScanNetworks

I use Arduino Uno Rev3(ATMEGA328P-PU) and Arduino Wifi Shield(ATMEL 32UC3A1512-U).

Picture:

  1. Arduino Uno Rev3: Dropbox - Error - Simplify your life
  2. Arduino Wifi Shield: Dropbox - Error

computer system: Windows 7

I upload all of the Wifi example and I always get ?WiFi shield not present?.

I have found this web page(openhomeautomation.net) and his youtube.

He only use USB connect to Arduino, and it's can work?

Is it possible the power not enough to make Wifi Shield work?

If I update Arduino Wifi Shield (ATMEL 32UC3A1512-U) firmware, this problem can be resolve?

I have found web page about update Arduino Wifi Shield. (binarytaskforce.com : 404 Not Found)

It say use FTDI, but I have no FTDI.(This is not cheap to me)

I'm not sure use FTDI to update Arduino WiFi Shield firmware is useful.

If update Arduino WiFi Shield firmware can resolve my problem, I can buy a FTDI.

By the way

I have a question about this web page. (http://arduino.cc/en/Hacking/WiFiShieldFirmwareUpgrading)

He say ?Download updated firmware for the 32UC3A1256?, but my Arduino Wifi Shield use ?32UC3A1512?.

So I have to search firmware?32UC3A1512? or use ?32UC3A1256? ?

That's all.

Insure the jumper is removed from the two pins next to the SD card slot. That will cause that fail. That jumper should be installed only when installing new firmware, which I recommend doing once you find the shield works.

Thanks for your proposal , SurferTim.

Arduino Wifi Shield works.
