Abstract

Con un circuito di ingresso su un ingresso digitale (2) di un microcalcolatore (1) deve poter venir rilevata in modo semplice come tecnica circuitale una pluralità di valori di ingresso.Ad uno sfasatore (10) per la tensione alternata, che è applicata al circuito di ingresso e con cui il microcalcolatore (1) è sincronizzato, può essere ogni volta applicato uno dei valori di ingresso. Lo sfasatore (10) regola lo sfasamento corrispondentemente al valore di ingresso effettivo. Lo sfasamento porta ogni volta ad un segnale di comando (UA) sull'ingresso digitale (2), corrispondentemente sfasato nel tempo. Il microcalcolatore (1) interroga l'ingresso digitale (2) e assume il valore di uscita associato al valore di ingresso o allo sfasamento, se al corrispondente istante d'interrogazione è presente il segnale di comando.With an input circuit on a digital input (2) of a microcomputer (1) it must be possible to simply detect a plurality of input values as a circuit technique. To a phase shifter (10) for the alternating voltage, which is applied to the input circuit and with which the microcomputer (1) is synchronized, one of the input values can be applied each time. The phase shifter (10) adjusts the phase shift corresponding to the actual input value. The phase shift leads each time to a command signal (UA) on the digital input (2), correspondingly out of phase over time. The microcomputer (1) interrogates the digital input (2) and assumes the output value associated with the input value or the phase shift, if the command signal is present at the corresponding instant of interrogation.
