초록
최근 우리 사회에 커다란 영향을 미쳤던 COVID-19은 공학교육 분야에 있어서도 해결해야 할 많은 과제를남겨주었다. 특히 기존의 오프라인 대면 물리적 실험 실습 대신 언제 어디서나 비용 부담 없이 시뮬레이션을통해 학습할 수 있는 가상실험 소프트웨어의 개발이 중요하게 되었다. 본 연구에서는 마이크로컨트롤러 응용시스템 설계 교육용 가상 실험 소프트웨어 개발 연구의 일환으로 마이크로컨트롤러가 주변 장치들과 정보를주고받을 때 사용하는 SPI 직렬통신 인터페이스 시뮬레이션 모듈을 설계하고 구현하였다. 개발된 SPI 통신모듈은 2개의 마이크로컨트롤러를 서로 연결한 회로를 구성하고, 설계된 SPI 통신 방식으로 데이터를 송수신하는지 가상 실험을 통해 확인함으로써 기능을 검증하였다. 앞으로 본 연구에서 개발된 SPI 통신 모듈로 인해 마이크로컨트롤러와 다른 주변 장치간 보다 다양한 인터페이스 지원이 가능하게 되고, 따라서 가상 실험실습을 통해 보다 실질적인 교육의 효과를 증대시킬 수 있을 것으로 기대된다.
Abstract
COVID-19, which has recently had a great impact on our society, has left many challenges to be solved in the field of engineering education as well. In particular, instead of the existing offline, face-to-face physical experimental practice, the development of virtual experimental simulation software that has many advantages such as anytime, anywhere and less cost, has become important. In this study, as part of the development of virtual experimental software for microcontroller application system design education, an SPI serial communication interface simulation module used by microcontrollers to exchange information with peripheral devices has been designed and implemented. The developed SPI communication module was verified by constructing a circuit in which two microcontrollers were connected to each other and checking whether data was transmitted and received according to the designed SPI communication method through virtual experiments. It is expected that the developed SPI communication module will enable more diverse interface support between microcontrollers and other peripheral devices, and thus increase the effectiveness of education through more practical virtual experimental practice.
