Has anyone had luck using Firmata + Pyduino, the Python library?
The Firmata sketch is located here: http://www.arduino.cc/playground/Interfacing/Firmata
but the download link is broken so I had to copy/paste from the CVS site. Only later did I find that Firmata is already located in a folder in the Arduino IDE (I'm on WinXP).
I've had no luck getting the Pyduino library and example to work. PySerial can connect to the Arduino's serial port without errors, but any attempt at one- or two-way communication (for example, getting the firmata version number stored in the sketch on the arduino) produces nothing. Other serial communication to my board using other sketches works fine.
