배선 문제로 pan만 연결했는데
전원부가 미친듯이 열받아서 보드를 손으로 잡고 있기 부담스러울 정도라
나중에 esp32와 서보 전원을 분리해서 만들어야 안정적으로 작동이 가능할것 같다.
IO15가 pan
IO14가 tilt 로 구성해둔 듯.

눈으로 보면 미친듯이 밝은데 생각외로 밝진 않은 느낌 -_ㅠ
가장 아래 Flash 버튼을 추가했음
Flash on!
새로 스케치 만들어서 붙여넣고
스케치 - 라이브러리 포함하기 - ESP32 하고
툴 - 라이브러리 관리 - esp32servo 설치하면 된다.

stm32f103 72mhz (cortex-m3)
esp32 240mhz
아키텍쳐가 달라서 완벽한 비교도 아니니 참고 수준이지만
cortex m3 보단 낫고
cortex m4 와는 비근하지만 약간 쳐지는 수준안가?

4번 핀이라는데 한번 테스트는 해봐야겠네
| #define LED_BUILTIN 4 pinMode (LED_BUILTIN, OUTPUT); digitalWrite(LED_BUILTIN, HIGH); digitalWrite(LED_BUILTIN, LOW); |
회도로 상으로는 LED / 9번 핀, GPIO33이라는데?
좀더 보다보니 LED가 아니라 LED_FLASH1 발견 -_-
HS2_DATA1은 GPIO4 / 26번 핀에 연결되어 있고 그게 바로 4번의 정체..

(대충 인두기를 사고 싶다라는 이야기)
ESP32-CAM에는 AMS1117 이라는 놈이 달려있는데
연구소에 있는 부품중에 1117로 검색해보니 IL1117C-3.3 뿐이라고 해서
핀 호환되는지 보니 일단 okay

레귤레이터 찍어보니 3.3V가 나와야 하는데 2.6V가 나오네
5V to 3.3V 레귤레이터를 좀 사둬야 하나...
그나저나 5V에서 3.3V면 1.7V 강하인데 2.6V 면은 2.4V 강하인데
머가 이상이 생겨서 더 떨어진걸까?
처음살때 찍은건데, LDO 에 흠집이 없어 보이는데
AMS1117의 S아래에 점 같은 손상흔적
열때문에 터진건가..

코드를 분석해봐도 안나와서 검색해보니
별도의 esp32-idf(Espressif IoT Development Framework) 라고 개발되고 관리되는 듯.

매번 켤때 마다 카메라 뒤집어 지고, 해상도 설정하기 귀찮아서 찾아봄
귀찮아서 아래 부분만 수정함.
카메라를 뒤집에서 설치해야 글루건으로 붙이기 용이해서 필수로 뒤집어야 하고
해상도가 QVGA로 되서 너무 화질구지라 XGA(1024x768) 정도로 하면 프레임도 나쁘지 않아 일단 이렇게 설정
