[PD] Pduino and the AD5206 digital potentiometer

[nick burge]

I got my AD206 chip as a free sample from analog devices 
http://www.analog.com/commerce/index.html
It would be great to have support within Firmata for SPI - (serial
peripheral interface) allowing control over this digital potentiometer or
other devices and sensors that work with that protocol when connected to an
arduino. 
Could it possibly work to simply copy sections of the code from the arduino
tutorial into the firmata firmware , first the definitions, then the void
setup section and then the write_pot(0,0) command to control the device into
the loop section.? As you can tell I have little idea how to do this.
Nick.

It would be possible to add support to Firmata for this, but it's not
currently there. I don't have any of these chips, any volunteers? Patches
welcome :D

Dear PD list. I would like to be able to control the AD5206 chip (a 6
channel digital potentiometer) from within the Pduino object written by
Hans-Christoph Steiner. The idea comes from one of the tutorial exercises in
the C++ arduino program.
http://www.arduino.cc/en/Tutorial/SPIDigitalPot
Is this relatively simple to do, or simply impossible? The aim in the long
run is to be able to be able to calibrate 6 force sensors remotely using the
digital potentiometers for an art installation project.
I have got the above mentioned tutorial project up and running succesfully
using the arduino program, and I am also able to get Pduino communicating
with the arduino quite happily on my Windows Vista system, but I would
imagine to have control over the the digital potentiometer device from
within PD would require a revision to the Firmata firmware would it not? I
would be most grateful for a clue.

thank you for your attention, sincerely, Nick Burge.
