heh SEO is also those jerkwads that spam your blog 150 times an hour telling you how great your post was but they could make you #1 on google if you only provide credit information

To date, Adafruit has not stated their items are Due compatible.  It's on their to-do list but not done.

You might post a code snippet of what you got working to help others trying to do the same).

Do you want to be able to define different serial devices as stdout?  Or hard code to say the main USB port?

You could define printf as just sending the char to the usb - open usb at the baud rate in Begin - Serial.begin(baudrate) then printf would send the char as a Serial.print(c); (the file handle would be ignored if you share a code base).
52  Products / Arduino Esplora / Re: Esplora not showing up in device manager; recommendation on solution? on: June 18, 2013, 11:39:15 am
Check the Windows Device Manager in Control Panel.  If it is listing an unknown device when Esplora is plugged in, click Update Driver.  Point it at your Arduino IDE 1.05 install directory which should have the Esplora driver.

If the lights are still blinking on the board, it sounds like more of a driver issue. 

If you have access to a different computer, you could try to talk to the Esplora via the 1.05 IDE on that to ensure it is not a board issue.

See for one implementation.  I have seen some of the LCD display drivers like gLCD and Adafruit do this also but they use the Arduino low level digital line manipulation routines to speed things up.

Would you please consider using web service (formerly cosm, formerly pachube) as it may be used in all countries?

This is a guess as I don't have one to test: it looks like the SPI is used for the SD card interface only.  Since it hooks into the right header, it should be getting the right signals.  It is using D4 as a select which should be compatible with the Due extended SPI.  But I am unsure if the Arduino team or someone else has completed a port of the SD library - you'll have to look around the forum - the new library would use different logical pins (at least it ises the SPI header rather than hardwired to Digital 11-13) .  I cannot tell from the picture if any of the SPI lines are routed to the bee socket but it is doubtful as that portion uses the serial line and not SPI.  You can follow the circuit board traces to see.

The Arduino team really should design and build a new shield that uses the IOREF pin on R3 Arduinos to see if the voltage regulating is really necessary.  The Bee devices and SD card are 3.3 volt devices.  Maybe they will at some point?

The shield documentation seems pretty clear - the TX/RX connect (crosswise) from the Arduino TX0/RX0 (D0/D1) to the bee socket pins used for TX/RX.  You need to have the switch set to "micro".  When you put the switch on "usb" it allows the USB port to program the Arduino by disconnecting the serial from the bee socket.
57  Products / Arduino Due / Re: Serial Port Question on: June 07, 2013, 11:38:11 am
Do your devices have more than the TX/RX serial pins?  Using other RS232 signals like clear to send, data set ready, etc. you could use a small external circuit to tell each device to wait and you'd poll each serial device in turn, using only one serial port and a control lines.

Of course someone completing a SoftwareSerial library would be the best solution.

Yes Xively (formerly Cosm, formerly Pachube) would be the English equivalent.  I have an Iboard collecting 4 temperature sensors data and reporting both to Xively and as a home web page (a bit tricky to combine). 

Note that unlike the description, the Iboard is not IEEE POE capable.  I do use the fake POE sending 9 volts up the line and splitting off again but I had bought an IEEE POE router for sensors before I knew the Iboard could not handle the 48 volt stepdown.

$17.50 is better than when I bought it, I have not seen that price lately on the iteadstudio website.

Actually the SAM is not programmed through ICSP like the AVR Arduinos.  So that is the only header they designed to access those pins.  They have also provided extended SPI functions at

There is a bit more consolidated info at
