Electronic control device

摘要

An electronic control device comprises a micro-computer M, an input matrix Clav and an output matrix A and is managed by an interrupt program. By means of a low-pass filter, R, C, and a comparator Cp the interrupt program carries out the functions of a digital- to-analog converter controlled by modulation of the pulse width. By means of comparator Cp, one thus simply forms an analog-to- digital converter allowing the acquisition of analog data by the micro-computer M.
