Abstract
본 발명은 헤드폰 스테레오(Head Phone Stereo)장치에서 기기 전체를 총괄 제어하는 시스템 마이컴과, 원격 제어를 담당하는 리모콘 마이컴, 그리고 라디오 수신기를 제어하는 튜닝 마이컴 사이의 직렬 데이타 통신을 수행함에 있어서, 1라인의 데이타 전송 선로를 이용하여 각 마이컴간의 데이타 입력과 출력 등의 통신을 수행할 수 있도록한 헤드폰 스테레오장치의 마이컴간의 직렬 데이타 통신 제어방법에 관한 것이다.The present invention provides a single line in performing serial data communication between a system micom for overall control of a device in a headphone stereo device, a remote control micom for remote control, and a tuning micom for controlling a radio receiver. The present invention relates to a control method of serial data communication between microcomputers of a headphone stereo device which enables communication of data input and output between microcomputers using a data transmission line.
종래의 헤드폰 스테레오 장치에서는 시스템 마이컴(1)과 리모콘 마이컴(2), 그리고 튜닝 마이컴(3) 사이에서 직렬로 데이타를 전송하기 위하여 다수의 전송라인을 확보해야 되고, 이는 곧 회로 구성상의 제약으로 나타나게 되며, 마이컴에 다수의 데이타 전송 관련 포트를 할당하는데 따른 운용상의 어려움이 초래되고,회로 구성이 복잡해지게 되는 문제점이 있다.In the conventional headphone stereo device, a plurality of transmission lines must be secured in order to transmit data serially between the system microcomputer (1), the remote control microcomputer (2), and the tuning microcomputer (3). In addition, there is a problem in that an operation difficulty in allocating a plurality of data transmission related ports to the microcomputer is caused, and the circuit configuration becomes complicated.
본 발명은 1개의 전송라인을 이용하여 시스템 마이컴과 튜닝 마이컴, 리모콘 마이컴 사이의 데이타 전송이 이루어지도록 하므로써 상기한 종래의 문제점을 해소하고, 회로 구성의 간소화를 기함은 물론, 마이컴 운용의 편리함을 기하며, 이에 따른 마이컴 포트수의 감소를 기할 수 있도록 한 것으로, 헤드폰 스테레오 장치에 적용한다.The present invention solves the above-mentioned problems by simplifying the circuit configuration as well as the convenience of the microcomputer operation by allowing data transmission between the system microcomputer, the tuning microcomputer, and the remote controller microcomputer using one transmission line. As a result, the number of microcomputer ports can be reduced and applied to a headphone stereo device.
