It took a bit longer than expected (or I had less time available than hoped for), but a extended��version of Firmata is available at��https://github.com/robvanlopik/Firmata. The main changes are:

- added support for i2c, stepper and encoder

- limited thread safety

- announcements for change of digital input and end of stepper motion

- access to capability request��and��analog mapping

- supports configurable Firmata

- easier to add new devices (accelstepper and one-wire are on my list)

- added a description of the API

I tested with different Arduino boards from a Windows��system through��a USB connection.

I hope you will take a look at the code and see whether it is worthy to replace the present version.

cheers
