Abstract:
1. An addressing type coin-dropping detector circuit that assigns a hardware address to perform an addressing operation, by which the circuit receives an impulse inputted by an external photo detector and outputs an impulse-length value to an external circuit, comprising: a bus; a data acquisition controller electrically connected to the bus, for receiving address and data from the bus; a plurality of control pins, used to control data transmission of the addressing type coin-dropping detector circuit; an addressing type input register, used to save the address and data inputted by the external circuit; a frequency divider circuit for receiving local clocks to perform dividing frequency; a plurality of counters for receiving the impulse from the external photo detector, so as to perform an impulse counting to generate an impulse-length value; a signal detector circuit, used to receive the impulse-length value outputted from the counters and output an enable signal to the external circuit; and an addressing type output register, used to receive the impulse-length value inputted by the counters and output to the external circuit.
