The Analog Thing is a pure analog device, there is no microcontroller or other advanced digital logic involved. Nevertheless, there are interesting cases when to combine the Analog Thing with software. One of the most urgent needs may be the neccessity of a software emulated Oscilloscope in order to display data.
Other things related software are about Hybrid Computing.
