초록

A firmware/hardware apparatus for controlling with digital signals the smooth operation of a needle of an electronic analog gauge meter even when the measurand data is provided intermittently.

대표
청구항

A firmware/hardware electronic analog meter control system used with a multi-measurand data communication system for measuring a chosen measurand and then moving a needle of a gauge of the meter in a manner analogous to changes in magnitude of the measurand to positions indicated by a series of integer numbers arranged linearly over a display scale of the gauge, the scale representing a range of magnitudes of the measurand from a minimum to a maximum value, the meter containing digital to analog conversion circuits and coil drivers for controlling needle...
