Hi,
In the Pduino test patch ("arduino-test.pd") there is a subpatch called "old analog/digital controls".
This includes a series of toggles which send the message "analogIns X Y" (where X is the analog pin to enable/disable and Y is either 0 or 1).
With the version I'm testing (which is Firmata 2.1 on an Arduino Duemilanove) those messages are actually needed in order to get the analog inputs to work.
Maybe those messages aren't needed with Firmata 2.2? That would explain the "old" in the subpatch name.
Thanks m.
