1  Products / Arduino Due / Wifi Connected to the Due Board but I get Wifi Not Present. Damaged Shield? on: January 23, 2013, 10:57:17 pm
Hello,

I've connected the wifi shield to my due board and imported the wifi library that is mentioned in the due forum. When I run the scan networks sketch I get: "WiFi shield not present."
Is it possible that my wifi shield is damaged (although I've never used it, just got it on Monday)? All of the LEDs on the shield are off, and when I press the reset button of the shield I get the same error message as above.

Is it a fried shield or connection problem?

Thank you

I should add that it'll be more of a freelance type job than actually "helping" on steps.

Hi,

I'm new to Arduino too, and live in Millbrae. Have you found any group in the Bay Area?
I've looked through meetup, but it doesnt look like they have an Arduino focused meetings (more general electronics....).

Yes, it's compatible with the Due based on all of the messages I've read and the schematics (the Due has ioref pin). But I don't actually know how to connect the two together, any suggestion?

Hello,

I'm new to Arduino boards, and I'm trying to prototype a device.
The project includes:
Phase 1: connect the Due board to the Arduino wifi shield and sd, write some functions as save file to sd or send file to server or email.
Phase 2: interface a camera with it (8bit black and white but should be high res).
Ideally, the helper resides in the Bay Area, but it's not a must.

If you have experience with either phase 1 or phase 2 and interested please message me on the board or at simply_me1(at)outlook(dot)com.

Thank you,

So, I've compared the schematics of the uno and the due regarding the wifi shield, and it seems that pins 11,12,&13 of the uno correspond to the SPI pins 109,108,&110 of the due, respectively. Is this correct?
Also, which are the pins that are used on the due to select SD or wifi modes? It says that on the uno it's pins 4 and 10. Also, in case of data transfer?
Here is a link to the uno schematics:

Schematics of the due (taken from the top post in this forum):

I Appreciate any input that you can provide.

Lastly, here is the wifi shield wiring description:
"Arduino communicates with both the Wifi shield's processor and SD card using the SPI bus (through the ICSP header). This is on digital pins 11, 12, and 13 on the Uno and pins 50, 51, and 52 on the Mega. On both boards, pin 10 is used to select the HDG104 and pin 4 for the SD card. These pins cannot be used for general I/O. On the Mega, the hardware SS pin, 53, is not used to select either the HDG104 or the SD card, but it must be kept as an output or the SPI interface won't work.
 
Digital pin 7 is used as a handshake pin between the WiFi shield and the Arduino, and should not be used.
 
Note that because the HDG104 and SD card share the SPI bus, only one can be active at a time. If you are using both peripherals in your program, this should be taken care of by the corresponding libraries. If you're not using one of the peripherals in your program, however, you'll need to explicitly deselect it. To do this with the SD card, set pin 4 as an output and write a high to it. For the HDG104, set digital pin 10 as a high output." How come it doesnt mention data bus?

Hello,

I'm interested in capturing 2-3 snapshots for step 1. The image should be b/w, high resolution (I guess ~3MP), and about 1cm by 1cm area (taken from abt 1cm height).

That being said, I've scanned the forums for CMOS camera and Arduino boards and didn't find any "headache free" solution, but apparently it is possible to do with the Due board! :-)
There are many mentions of

http://www.arducam.com/

Honestly, I would have bought the arducam if it worked with the Due. The main goal in using Arduino in this project is to prototype fast (faster than it'll take to design a whole board from scratch) and show a proof of concept, and hence I'm not looking to reinvent the wheel; but looking for simple, straight forward solution.
Would you guys have any suggestions? Maybe other directions I should check?

Thanks in advance.
8  Products / Arduino Due / Simple Question About WiFi Shield Wiring to the Due Board on: January 22, 2013, 02:00:56 pm
Hello,

I've received my first Arduino board last weekend (together with a wifi shield). While I've found the wiring for other boards and the shield ("Arduino communicates with both the Wifi shield's processor and SD card using the SPI bus (through the ICSP header). This is on digital pins 11, 12, and 13 on the Uno and pins 50, 51, and 52 on the Mega...."), I can't find the wiring for the shield with the due board.
Can someone share a typical wiring? And briefly explain the logic behind it....

Also, I plan to have an analog switch that will let the user choose between the SD or wifi on the shield (so I'm guessing a switch will be connected to pin 4 and pin 10 of the due? reading which one is high)

Thank you for your help in advance.
