A rotary encoder replaces a rotary potentiometer, while providing a long live due to no wiper degrading the substrate.
How can I replace a linear potentiometer (a "fader") with something following the same fashion ?
I have a certain appliance that has DSP equalization internally. I can change the coefficients via i2c. I want to keep the usual "equalizer" visual and feeling, by using pots, but, in order to get something more modern, i wanted to replace the usual linear slider analog pots for linear encoders, read them using a microcontroller and send the values via i2c.
Everything is on a box and from outside you cannot tell that everything is being done inside a dsp digitally. It looks and feels like a old school equalizer...
