I am unlikely to write software for that chip unless I have a use for
it. But a firmware supporting it sounds useful. Firmata is an
Arduino library, so the easiest route would probably make a dedicated
firmware for that chip then use the Firmata to handle the
communications.

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.From: Hans-Christoph Steiner [mailto:hans@eds.org] Sent: 04 March 2008 14:39 To: nick burge Cc: 'Pd List' Subject: Re: [PD] Pduino and the AD5206 digital potentiometer
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.hc

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. _______________________________________________ PD-list@iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/ listinfo/pd-list
