I wonder if this technology exists.
Imagine the following situation:
During setup/calibration I can power the circuit and "tune" my potentiometer using some type of digital interface. (e.g. I2C)
However, during operation the device is fully passive and will not have a source of power. Thus, the potentiometer would need to "remember" the settings and operate passively.
Currently I use standard potentiometers, but tuning them manually is way too cumbersome and not practical.
Ideas?
