Wiring up the CFU Display

The CFU (Cat Feeder Unreminder) will notify the user that it is safe and timely to feed the cat through a use of a TN style LCD. These are typically a 7-segment style instead of graphical. The CFU also needs to notify the user that the device is still operating.

Part Number: VI-422-DP-RC-S

The common (COM) pin of the display will be directly connected to one leg of the oscillator circuit. Depending on where the other leg of the oscillator is routed, the display will either show “FEEd” or will light up the S1 segment.
