It's easy to use that 1.8" TFT with the right pin numbers and the Adafruit libraries for the display. I just got it going yesterday. Look at my post on Google+

And the comments.

Here's the key. Look in the first lines of the graphicstest sketch from Adafruit. You should change them to look like this:

// You can use any (4 or) 5 pins
#define sclk 15
#define mosi 16
#define cs   7
#define dc   0
#define rst  1  // you can also connect this to the Arduino reset

You'll also have to rotate the display to landscape. Comments on my post show how, or you can read the tutorial pdf from Adafruit.

Good luck.

I know I am too late to help, but this may help others with this problem. c. kazah writes "I get a perferct reading on the serial monitor window." And that seems to be the problem. With the graph processing sketch, at least, you cannot have the serial monitor on in the arduino window - it seems to make the serial output of Arduino erratic. Processing starts getting spurious strings that are empty or corrupted concatenations of the right reading. And those spurious strings are reflected in the Arduino serial monitor.

First thing, try disabling the serial monitor, then hold down reset button until Processing is running again. That is the only way I could get it running properly again after I had also turned on the serial monitor.

Mellis, is there a fix for this?

Thanks

Yes, I've seen a page that verifies that.

Just got my Funnel IO's - Nice work, but could you give us a hint which way the Xbee goes in the socket? I suppose I could puzzle it out, but a photo here (or on the funnel site) would help a lot of folks.

Thanks, when you can. I'll check the playground.

Any more info available on the Vtech toy control with 4051's? Just saw those at good prices at Lot Less, near Chambers and Church if you are in Manhattan, and wondered what you could do with the.

A drawing of the circuit maybe?

I do not have the Xbee shield but I think you are confusing the situation. First read the Xbee shield pages carefully again:

http://www.arduino.cc/en/Main/ArduinoXbeeShield

and I also highly recommend the Tom Igoe book, Making Things Talk.

My understanding is that the jumpers on the shield control communications with the computer that is hooked up to the USB connector on the Arduino. The microcontroller is removed only to configure the Xbee itself from the computer. Once the Xbee is configured, and the Arduino has a sketch uploaded to firmware (and this is done on both Arduinos and shields) there should be no reason to remove the microcontroller. The Xbee transmission in its simplest form can act as a wireless serial link between the Arduinos.

But I am also new to this - as I suggested, get the book.

On sale now at Sparkfun but they are currently out of stock.

Yes, that last suggestion was exactly right. I had the same problem, and had just been trying to get Exemplar to run on my Mac. It required putting RXTX in the Java extensions. Once it was moved out, problem disappeared (Although I haven't gotten Exemplar to run - anyone else have any luck on OS X?)

The above URL was truncated. Should end in .html

Look at this page also to see how to configure two Xbees to talk to each other:

And by all means buy the Tom Igoe book, Making Things Talk. Very clear instructions on configuring Xbees.
