com port

My post on the Arduino forum http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1272485104 was answered very quickly and what I had established yesterday was backed up. It was a problem with the serial port which was not being identified as open.

"port = new Serial(parent,"/dev/cu.usbserial-A900705s",9600);"

What I hadn't realised this time was since I changed my board the port number also changed.
I had copied the port number from the arduino tool bar into my sketch before, but since double checking it after this post, I realised the number at the end of the port had now changed to "/dev/cu.usbserial-A70060ta". I am assuming this is what happened. Anyway, there is light at the end of the tunnel. The Led Matrix is now responding, although not as expected. Only four of the 64 leds are responding to movement, but it is a vital step; we now have communication between processing and the board.
My Matrix differs from the one used by Bryan Chung in several ways. Mine displays 7 different colors being a full R/G/B serial interface matrix with its own backpack. All the refreshing and communication control is taken care of by the backpack. Bryan Chung had developed his own custom PCB back back board.



An interesting thing here is that we were getting some colour change response as well as a simple on or off response to light conditions. The refresh rate or reaction time to changing light conditions was very slow for some reason. This is a great start, but from here the real challenge will begin.
