접지, hot, 중성으로 해서
릴레이로 끊을시 hot(220V)를 끊어주는게 그나마 낫다는데
테스터가 없으면 어떻게 판별을 하지?

J1핀을 제거하면 USB OTG 포트를 전원 입력으로 사용할 수 없게 된다.
이 것은 전원 소비와 발열을 크게 감소시킬 것이다.
odroid-c2는 비디오 재생이나 몇몇 주변장치를 사용하는데 0.8Amp 이상을 소비하는데
USB port에 장치가 연결되면 1.5 A 이상을 연결하길 권장한다.
그런데 OTG가 도대체 (?) 머길래 전원 소비와 발열을 줄인다는거지?
| Remove the Jumper on J1 if you don't use the USB OTG port as a power input It will reduce the power consumption and heat significantly. Since ODROID-C2 can consume current more than 0.8Amp by itself while playing a video file or with some peripherals - keyboard/mouse/WiFi dongle - are attached to USB port, we strongly recommend to use 5V USB charger with minimal 1.5Amp+ can be supplied. Please note that still DC jack works with the same specification of ODROID-C2 apart from USB OTG for power supplying. |

일단은 다행히(!) odroid u3에 쓰던 어댑터가 맞는것 같으니 바로 테스트 해봐야겠다..

OTG를 통해 쓰는거다 보니 바로 써지진 않고 sync나 umount 이후에 갱신되는게 확인된다.

| ADC's maximum sample rate is 50kSPS. ODROID-C2 has 10bit resolution (0~1023). ODROID-C4/N2 has 12bit resolution (0~4095). But the actual sample rate is 8kSPS if you access it via sysfs due to the limited file IO speed. |

젊어서(?) 그런가 어떻게 된게 예전 복실이 보다 유지비가 많이 드냐 ㅠㅠ
동물등록 2만
진료비 1.1만
피부약 2만?
검사비 2만?
약 값 얼마
머 대충 이렇게 합산되서 8.2만 정도 나왔던 듯
아무튼 세균성 피부병이라 언넝 낫길
그 와중에 냄새 이상해서 버리려고 놔둔 햄을 (1kg) 한 200g 남기고 다 먹으심 -_-

irrecord가 ubuntu 20.04 에서 안되서 일단 18.04로 시도해서 성공.
ubuntu-18.04.3-3.16-minimal-odroid-c2-20190814.img
다시 한번 irrecord -f 옵션으로 20.04에서 시도해봐야 할 듯.
+
20.04 에서 해봤는데 -f 옵션으로 raw 처리하니 입력은 받을 수 있는 듯.
값이 미묘하게 다르긴 하지만 되는 것 같기도 하고?
GPIO IR 회로.
[링크 : https://wiki.odroid.com/odroid-c2/application_note/gpio/lirc_gpio_blaster]
간단하게 IR LED를 9번과(IR LED -극) 11번(IR LED +극)에 연결하면 된다.
거리가 60cm 정도만 떨어져도 인식이 안되기 시작해서 문제지 -_-
그래서 TR을 이용해서 전원을 공급받고 GPIO로 On/Off만 해주는 건가..

irrecord -r 옵션을 주니 세세하게 내용이 다르게 생성된다.
그래도.. raw 옵션주고 만드는데 나중에 추가하기 편하려나? mode2로 생성할때도 raw로 나오니까?
이제 odroid c2에 IR LED 달고 출력도 되면 개꿀~!

라즈베리 파이 zero에서 USB 메모리 스틱처럼 인식을 시킬수 있다는데
2B나 3B 등에서는 아무래도 회로적으로 USB OTG 구성이 되어 있지 않으니 안될 것 같고
rpi CM4만 해도 OTG가 굽는 용도로 있으니 어떻게 든 가능할 것 같은데.. 확신은 없음
반대로 OTG가 존재하는 odroid 등에서는 가능하려나?

머가 문제일까..

stretch가 문제가 아니라
decoded에 문제가 있는지 raw로 하니 잘 된다.
