Abstract

본 발명은 피아이오(PIO)를 이용한 캔 콘트롤 장치에 관한 것으로서, 이는 캔 콘트롤러의 회로 동작에 필요한 멀티플렉서 회로등 복잡한 회로를 제거하고 간단한 피아이오를 이용하여 회로의 단순화를 추구하고 캔 콘트롤 칩이 구동하기 위한 콘트롤 신호(WR, RD, CS)의 연결 또한 소프트웨어를 통한 프로그램으로 피아이오를 통해 캔을 제어하도록 한 것이다.The present invention relates to a can control device using a PIO, which eliminates complex circuits such as multiplexer circuits required for the operation of the can controller and seeks simplicity of the circuit using a simple PIO and drives the can control chip. The control signals WR, RD, and CS are connected to control the can through PIO through a software program.

이와같은 본 발명 피아이오(PIO)를 이용한 캔 콘트롤 장치는 외부의 중앙처리장치로부터 입력되는 2비트의 어드레스와 칩선택신호, 기록신호, 판독신호에 따라 입력 8비트의 데이타를 기록함과 아울러 기록된 데이타 및 상기 제어신호들을 인터페이스하는 피아이오와; 상기 피아이오로부터의 캔 콘트롤러 동작에 필요한 제어신호를 인터페이스하는 콘트롤버스와; 상기 피아이오에서 제공되는 8비트의 데이타를 양방향으로 송수신하는 데이타버스와; 상기 콘트롤버스에서 제공되는 제어신호에 따라 동작하여 데이타버스를 통해 제공되는 데이타를 가지고 외부 ECU들과의 송수신을 하는 캔으로 이루어짐으로서 달성된다.The can control device using PIO according to the present invention records 8-bit input data according to a 2-bit address input from an external central processing unit, a chip select signal, a write signal, and a read signal. A piao for interfacing data and the control signals; A control bus for interfacing control signals required for operation of the can controller from the PIO; A data bus for bi-directionally transmitting and receiving 8-bit data provided by the PIO; It is achieved by operating in accordance with a control signal provided from the control bus and a can for transmitting and receiving to and from external ECUs with data provided through the data bus.
