Thanks for this hopeful reply!
I will be following up with some specific problems regarding the Pduino / Firmata I encountered.
To put it short it seems to me that things works much better with the older Firmata v2.1 than the newer ones.
Among some problems were problems to setup I/O digital pins from within Pd-patch. 
But as said, I will return with some specifics within a week or two.

The Pduino version you did Roman, with less dependencies, was that released the ordinary ways - and might it even be searchable through Deken?  If so... what to look for?

All the best,
Björn Eriksson

I once made a pduino version that uses less dependencies. I consider it
well tested with Firmata v2.2 and v2.3. I see that the current arduino
IDE (1.8.1) ships with Firmata protocol version 2.5.1.

I didn't track the changes since 2.3. However, I'm willing to fix
pduino if there is some indication that pduino is not compatible with
more recent Firmatas.

Please be as specific as possible in reporting what's not working for
you.

Roman
