윈도우 에서 삽질하다 포기하고 리눅스로 넘어왔다.
첨부터 리눅스로 할껄...;;
필요한 프로그램 설치
apt install gcc-avr avr-libc avrdude |
다른 곳에서는 binutils 와 uisp 까지 설치 하라고 되있는 곳도 있던데...
일단 테스트 결과 네모 안에 있는 3개만 설치해도 빌드 및 프로그램이 가능함을 확인 하였다.
avr-gcc, avrdude 만 있음 되는 거 같다... 일단은 -_-
음영으로 표시된 부분이 명령창에서 입력하는 부분이다.
1. 소스 작성 (cpp)
2. Makefile 작성
3. 컴파일 -> hex 파일 생성
4. 프로그램 -> hex 파일 을 ATMega328p 에 전송 (USBASP 2.0 사용)
5. 퓨즈비트 세팅 -> 내장클릭 1Mhz 를 사용하지 않고 외부의 16 MHz 크리스탈을 사용하여 동작하도록 설정
잊어먹기 전에 정리.... -_-;;
안되서 맨날 시방시방 하다가 되니까... 이 기분을 어찌 표현해야 할지... ㅎㅎㅎ
펌웨어 버젼 어쩌고 경고 뜨는데, 현재로서는 모르겠다능 -_-;;
펍업 하다 USBASP 해먹으면... 진행을 못하니까... 열댓개 사서 시도를 해보던가 해야겠다.
