먼저 블럭다이어그램을 통해서 타이머 종류를 살펴봅니다.
16bit타이머인 TAU0 - 4채널, 와치독 타이머, 12bit interval timer가 보입니다.
기본타이머인 16bit 타이머 TAU0 0채널을 사용하여 millis()함수를 만들어 보겠습니다.
프로젝트를 생성 후 Code Generator란에서 Timer를 선택하면 다음과 같은 메뉴가 나옵니다.
타이머 모드가 몇가지 존재하는데 간단하게 채널 0번을 Interval timer로 설정 하였습니다.
1ms Interval value를 설정합니다.
타이머 인터럽트를 사용할 것이므로 하단의 Generates INTTM00을 체크합니다.
Reflect in PIN 및 Generates Code를 클릭하면 다음과 같이 파일이 생성됩니다.
저의 경우 Watchdog을 unused 했으므로 wdt 파일은 생성되지 않았습니다. (Default는 생성됨)
r_cg_timer_user 함수는 인터럽트가 발생하는 Vector가 있는 함수입니다.
