We did this for some telco equipment we upgraded. We replaced 5 sets of 8
dip switches (yes, 40 in total) with a small 8x1 LCD and three pushbuttons.
We then used an 18-pin microcontroller (not PIC that time) with some EEPROM
on it, and the dip switches became virtual. The user selected the settings
off the screen. We also used the LCD's user-programmable characters to
graphically simulate the old dip switches. The whole thing ended up taking
less space than the original dip switches. More expensive, of course (but
on the equipment it went into that didn't matter), but much more versatile
and more fun!
