Abstract

본 발명은 마이컴을 이용한 전자기기의 키입력 인식방법에 관한 것으로, 특히 다수의 저항과 스위치를 순차적으로 직·병렬로 연결한 키입력부(10)를 통해 키입력신호가 발생하면 이를 디지탈신호로 변환한 후, 이 변환된 신호를 통해 키입력을 인식함에 따라 부품수를 감소시키고 제품의 생산가를 절감하는 효과가 있다.The present invention relates to a key input recognition method of an electronic device using a microcomputer, and in particular, when a key input signal is generated through a key input unit 10 in which a plurality of resistors and switches are connected in series and in parallel, a digital signal is converted into a digital signal. Then, the key input is recognized through the converted signal, thereby reducing the number of parts and reducing the production cost of the product.
