Michu, thanks for your help. Mac OS X Lion is playing it difficult I think. :-/ I did what you suggested (and I know that the Serial port IS accessible because then the DTR/Reset is connected the Rainbowduino Flashes a couple times while Processing is trying to access the ports...) however, I still get this: (This is when running the seeedstudio example, or your i2cScanner example... it's all the same. Any hints please??? =----- Result: ------= Oct 15, 2011 8:14:09 PM com.neophob.lib.rainbowduino.Rainbowduino INFO: Initialize neorainbowduino lib v1.7 Stable Library ========================================= Native lib Version = RXTX-2.1-7 Java lib Version = RXTX-2.1-7 Oct 15, 2011 8:14:09 PM com.neophob.lib.rainbowduino.Rainbowduino INFO: open port: /dev/tty.usbserial-A5005C6D Oct 15, 2011 8:14:11 PM com.neophob.lib.rainbowduino.Rainbowduino waitForAck INFO: No serial reply, duration: 32ms Oct 15, 2011 8:14:11 PM com.neophob.lib.rainbowduino.Rainbowduino openPort WARNING: No response from port /dev/tty.usbserial-A5005C6D Oct 15, 2011 8:14:11 PM com.neophob.lib.rainbowduino.Rainbowduino openPort WARNING: Failed to open port /dev/tty.usbserial-A5005C6D: com.neophob.lib.rainbowduino.NoSerialPortFoundException: No response from port /dev/tty.usbserial-A5005C6D Oct 15, 2011 8:14:11 PM com.neophob.lib.rainbowduino.Rainbowduino INFO: open port: /dev/cu.usbserial-A5005C6D Oct 15, 2011 8:14:13 PM com.neophob.lib.rainbowduino.Rainbowduino waitForAck INFO: No serial reply, duration: 31ms Oct 15, 2011 8:14:13 PM com.neophob.lib.rainbowduino.Rainbowduino openPort WARNING: No response from port /dev/cu.usbserial-A5005C6D Oct 15, 2011 8:14:13 PM com.neophob.lib.rainbowduino.Rainbowduino openPort WARNING: Failed to open port /dev/cu.usbserial-A5005C6D: com.neophob.lib.rainbowduino.NoSerialPortFoundException: No response from port /dev/cu.usbserial-A5005C6D

Hello... I've struggled to make this work on Mac OSX Lion. I don't know if it's the operating system's fault... but any of the examples (e.g. the Scanner or Simple) all give me exactly the same output. I've patched the libraries and everything...

Device address is set to 0x06 (changed and compiled in rainbow.h) and when I run i2cScanner it finds device 6 INFO: open port: COM1 Feb 6, 2011 12:39:32 PM com.neophob.lib.rainbowduino.Rainbowduino INFO: found serial port: COM1 Feb 6, 2011 12:39:32 PM com.neophob.lib.rainbowduino.Rainbowduino waitForI2cResultAndAck INFO: Reply from I2C device: #6 Found i2c devices: [6] Then it starts scrolling data but still have the default image...verified cabling with wiki, SCL - Analog5 and SDA - Analog4 Everything seems to be correct, but still no dice. Sorry for the trouble, but I do appreciate your help.

Thanks...I missed changing the buffer size on one of the files...now when I run one of the examples I don't see any error codes and according to the Processing window everything looks good (SpaceInv) show the following code Feb 6, 2011 10:53:17 AM com.neophob.lib.rainbowduino.Rainbowduino INFO: Initialize neorainbowduino lib v1.7 Stable Library ========================================= Native lib Version = RXTX-2.1-7 Java lib Version = RXTX-2.1-7 Feb 6, 2011 10:53:17 AM com.neophob.lib.rainbowduino.Rainbowduino INFO: open port: COM1 Feb 6, 2011 10:53:19 AM com.neophob.lib.rainbowduino.Rainbowduino INFO: found serial port: COM1 ping: true intro part doneRGB: 16, 244,239 RGB: 54, 129,201 RGB: 113, 255,142 RGB: 72, 209,183 etc. However the matrix stays on the default image. I currently have I2C connected to Arduino Analog pins 4&5...not sure what I'm doing wrong. Thanks in advance!

Hey there...thanks for all your hard work with this firmware! I have some of the same issue as the other guys above...I have the default image on my 8x8 matrix, I have flashed the firmware on both the rainbowduino and the arduino uno and installed the processing libraries. When I run the "simple" example my tx/rx lights are flashing like crazy but the default image stays on the matrix and this appears in my processing window...

hey there! great effort you are doing here! i tried the stuff, uploaded the fw to arduino, and rainbowduino. i get the static startup image on the display, when i use the i2cscanner, my device responds positively. now when i use a sample processing sketch what i get is this: neorainbowduino version: 1.4INFO: found serial port: COM4 ping arduino, result: true Last Timestamp at 12 Nov 2010 00:54:13 GMT Arduino Serial Buffer Size: 0 last arduino error: 2 12.11.2010 00:54:14 com.neophob.lib.rainbowduino.Rainbowduino waitForAck INFO: Invalid serial data [0, 0, 0, 0, 0, 0] Last Timestamp at 12 Nov 2010 00:54:16 GMT Arduino Serial Buffer Size: 0 last arduino error: 2 Last Timestamp at 12 Nov 2010 00:54:18 GMT Arduino Serial Buffer Size: 0 last arduino error: 2 Last Timestamp at 12 Nov 2010 00:54:21 GMT Arduino Serial Buffer Size: 0 last arduino error: 2 Last Timestamp at 12 Nov 2010 00:54:23 GMT Arduino Serial Buffer Size: 0 last arduino error: 2 the rx/tx leds on the arduino keep blinking, but the rainbow is not showing anything but the static image thanks saw0

I found what I think might have been the problem. In Rainbowduino.java I changed part of initPort to this: for(int i = 0; port == null && i < ports.length; i++) { if (PApplet.match(ports[i], port_name) != null) { log.log(Level.INFO, "open port: {0} " , new Object[] { ports[i] }); openPort(ports[i], check); return; } } log.log(Level.WARNING, "Couldn't initialize serial port"); as the "tty" lines were causing problems for me on my PC. After that modification, it works great!
