Abstract

PURPOSE: To make it possible to count different pulses without using an external counter, by counting pulses in time-division by means of a single microcomputer in an automobile meter panel.
CONSTITUTION: The signals from car-speed sensor 1 and distributor contact 2 are subjected to waveform shaping respectively by 4 and 5 and are input to microcomputer 6; and its output is latched and is fed to liquid crystal display element 9 via drive circuit 8: and thus the car speed and the number of revolutions of the engine are displayed. Counting of pulses at this time is performed in time division by computer 6.
