<div>손이 빠른데다가 막내라서 여기저기 끌려 다니는 서러운 개발자라서</div> <div>저번주 목/금 바빠서 글을 적지 못했네요 ㅠㅠ</div> <div><br></div> <div>아무튼 오늘의 주제는 <b>임베디드 개발자가 알아야 할 기본 상식 </b>입니다.</div> <div><br></div> <div><br></div> <div>임베디드는 범용이 아닌 특정 하드웨어에 특화되어 만들어지는 시스템입니다.</div> <div>즉, 범용이 아니기에 제품별로 하드웨어가 모두 다르고 <span style="font-size:9pt;line-height:1.5;">연결되는 방식이 다릅니다.</span></div> <div><span style="font-size:9pt;line-height:1.5;">그렇기에 이런 내용들을 파악하기 위해서는</span></div> <div><span style="font-size:9pt;line-height:1.5;">"<b>회도로</b>"를 볼줄 알아야 합니다</span></div> <div><span style="font-size:9pt;line-height:1.5;"><br></span></div> <div><span style="font-size:9pt;line-height:1.5;">회로도는 대개 <b>artwork</b>이 된 pcb 패턴과 </span><span style="font-size:9pt;line-height:1.5;"><b>schematic </b>회로 두가지를 의미합니다.</span></div> <div><span style="font-size:9pt;line-height:1.5;">schematic은 orcad 등으로 설계한 기능 레벨의 칩과 칩의 연결도를 의미하고</span></div> <div><span style="font-size:9pt;line-height:1.5;">GPIO 나 어떤 핀에 어떤 장치가 연결되었는지 확인하는데 쓰인다면(<b>프로그래밍용</b>)</span></div> <div><span style="font-size:9pt;line-height:1.5;">artwork된 회로는 pcb 보드 상에 어떤 선을 따라서 어떤 장비가 연결되었고</span></div> <div><span style="font-size:9pt;line-height:1.5;">프로그램으로 디버깅이 안될때 오실로스코프를 가져와 직접 값을 전기적으로 읽어볼때 쓰입니다(<b>디버깅용</b>)</span></div> <div><span style="font-size:9pt;line-height:1.5;"><br></span></div> <div><span style="font-size:9pt;line-height:1.5;">그렇기에 어느정도 회로를 볼 줄아아야 하는데</span></div> <div><span style="font-size:9pt;line-height:1.5;">회로의 기본은 부품입니다.</span></div> <div><span style="font-size:9pt;line-height:1.5;">LRC 라고도 하는데 Inductor(코일) / Resistance(저항) / Capacitor(콘덴서/캐패시터)가 있으며</span></div> <div><span style="font-size:9pt;line-height:1.5;"><b>코일은 L</b>000<b> </b></span><span style="font-size:9pt;line-height:1.5;"><b>저항은 R</b>000 <b>캐패시터는 C</b>000 으로 번호가 붙으며<b> </b></span><span style="font-size:9pt;line-height:1.5;"><b>IC들은 U</b>000로 붙습니다.</span></div> <div>이런 규칙은 업체별로 다르지만 이러한 룰이 있다는 정도만 알아두시면 편할 겁니다.</div> <div><br></div> <div>schematic 회로</div> <div> <div
