This decoder interprets the digital output of cheap generic calipers
(usually made in China), and shows the measured value in millimeters
or inches.

Notice that these devices often communicate on voltage levels below
3.3V and may require additional circuitry to capture the signal.

This decoder does not work for calipers using the Digimatic protocol
(eg. Mitutoyo and similar brands).
