Anything you that is added to peggyGroup in Main.mxml will be drawn to the Peggy. So, just add an s:Image to the group and you are good to go.

Hi,
I finally can work with Peggy with Flex. Thanks a lot!!
But i would like to ask one more question, how can i display images using that Flex project?

Thanks a lot!!

The latest version of AIR is 2.6 (it’s not the same as the Flex SDK). Try changing the SDK to Flex 4 and the namespace to

Are you sure it’s 3.5? I think it might be looking for 2.5, which means you’d need to updated the namespace in the Main-app.xml to “http://ns.adobe.com/air/application/2.6″ (or 2.5). Let me know if that works.

Awesome,
these sketches made me to visit the awesome design processes..
Thanks Sneh for great collection.

Unfortunately the TWI interface is managed via the Wire Arduino library, which utilizes two specific outs on the Arduino. I'm not sure if any of the other ports on the Arduino can be used for TWI, but if so, you'd probably have to look at the Wire library code and rewrite it to output to multiple wires (you may need a different type of Arduino, not sure). Otherwise, you can always use two Arduinos and synchronize them. Let me know if you figure it out!

Is it possible to use this code for 2 Peggys ? One Peggy is not enough for text scrolling
What about the wiring ?
Thanks

Hi there! Tilt was having the same problem, please view his thread regarding that error. You will need to edit the whiterabbit.properties file. Let me know if you still have some problems.

Hello again, still can't get it to work, I need some help..I'm getting this error:

at gnu.io.CommPortIdentifier.getPortIdentifier(CommPortIdentifier.java:218)
at com.whiterabbit.arduino.SerialProxy.connect(SerialProxy.java:62)
at com.whiterabbit.arduino.SerialProxy.main(SerialProxy.java:215)

What to do ?

Thanks in adv.

Ya, I didn't entirely test the app under the new SDK. I think if you try the webcam twice it will work fine, otherwise you may have to go into the code yourself and figure out where the null is coming from.

YES!!! Finally got it to work now!!!
The only thing that didn't work for me was the webcam option.
i get:

Ah yes, I built that project against an older version of the Flex 4 SDK (contained a reference to VideoElement, which has changed to VideoDisplay). I updated the project inside fierce_files.zip to work with the new SDK, please download it and let me know if it works for you. Here is a link directly to the FXP: http://bit.ly/aQyEnl (right-click and click save link as - make sure it's named *.fxp).

Alright, managed to overlay the Air 2.0 with Flex 4 SDK, so that error disappeared.
But now i get a NEW error:

1046: Type was not found or was not a compile-time constant: VideoElement. Main.mxml /fierce_led_matrix/src line 43 Flex Problem

1180: Call to a possibly undefined method VideoElement. Main.mxml /fierce_led_matrix/src line 67 Flex Problem

When i run it, the application opens, but its not showing on my Peggy, only because i think these two errors are probably why.
Any more hints? I have a feeling i'm really close to getting this work
Thanks again, and sorry if this is such a hassle for you!

You have done nothing wrong, you just don't have the Air 2.0 Beta SDK installed. Please refer to the following link for how to overlay the beta SDK into the Flex 4 SDK: http://labs.adobe.com/wiki/index.php/AIR_2:Rele...

The "Flex 4 / Air 2.0" SDK my project was referring to was created by following the steps in the above link. The Datagram class isn't available anywhere but the Air 2.0 SDK. Let me know if that works.

Okay, i changed the whiterabbit.properties file such that port.name=COM3, because my Arduino is on COM3.
Also, you forgot to mention how i needed the rxtxSerial.dll file in my jre directory.
Everything seems to work fine for the java part of the process.
However, i am now facing the problem with flash builder when i import the project whereby i get,

Unknown Flex SDK: "Flex 4.0 / Air 2.0" error

Therefore, i assumed the project Flex compiler and build path was incorrect again, so i chose the defualt Flex 4.0.

This prompted me with a new error:

1046: Type was not found or was not a compile-time constant: DatagramSocketDataEvent. PeggyProxy.as /fierce_led_matrix/src/com/whiterabbit/arduino/peggy line 134

Any hints on what i should be doing or have done wrong?
Thanks for all the help!

You did a great job and just outlined the steps above needed to make it work! As for that error, you need to go into the Arduino IDE and find your arduino device ID (Tools -> Serial Port -> find the ID). and edit the config file inside the project (filename: whiterabbit.properties). Replace the existing device ID with yours. That should remove that error! Let me know if you need anymore help.
