When I start the standard Firmata program from the Firmata website (firmata_test) I get a blank box coming up, with text at the bottom saying "Please choose serial port".
But as the screen is just a blank box, where do I select the serial port ?
Arduino s/w work fine and I can download files, communicate over the serial port using the Arduino s/w.
What are you trying to do with Firmata. I just uploaded one of the Arduino included example sketches to my Arduino. That's all you do on the Arduino side.
Then I went and started programming in Processing to get my project off the ground.
same problem here trying to run firmata_test on Ubuntu 12.04. I have loaded examples-firmata-standardfirmata via IDE 1.0 and I just get a vertical window asking me to choose port, but window has no buttons ....
