I would like to control a digital pot using Arduino as shown here: http://arduino.cc/en/Tutorial/SPIDigitalPot.
Of course I want to use MaxMSP instead of Processing. I've been able to flash LEDs, and get digital and analog input into Max through Maxuino/Firmata. However I think I've found a limitation with the serial object. The AD5206 uses SPI. Conceivably I could add the necessary functionality to Firmata, but how would the serial object communicate? Am I better off going with udpsend? Should I invest in an ethernet shield? Any advice is helpful.
