표시 장치와 RTC

TM1637 4자리 FND

IsegBegin()으로 CLK·DIO 핀을 설정한 뒤 IsegBrightness(), IsegDecimal(), IsegHex(), IsegWrite(), IsegClear()를 사용합니다. device 번호로 최대 7대를 구분합니다.

PCF8574 문자 LCD

IclcdBegin(address, columns, rows)으로 시작한 뒤 IclcdSetCursor(), IclcdPrint(), IclcdClear(), IclcdBacklight() 등을 사용합니다. device 번호로 최대 4대를 구분합니다.

DS3231 RTC

명령어	설명
`IrtcBegin()`	RTC 연결을 확인하고 사용을 시작합니다.
`IrtcSet(…)`, `IrtcRead(dateTime)`	날짜·시간을 설정하거나 읽습니다.
`IrtcUnixTime(unixTime)`	Unix 시간을 읽습니다.
`IrtcGetTemperature(temperature)`	RTC 내부 온도를 읽습니다.
`IrtcSetAlarm1(…)`, `IrtcSetAlarm2(…)`	알람을 설정합니다.
`IrtcAlarmEnable(…)`, `IrtcAlarmTriggered(…)`	알람 사용 여부와 발생 상태를 관리합니다.
`IrtcSquareWave(…)`, `Irtc32kHz(…)`	주파수 출력을 설정합니다.

void setup() {
  IsegBegin(22, 23);
  IsegDecimal(1234);
  IclcdBegin(0x27, 16, 2);
  IclcdPrint("ILOGICS");
  IrtcBegin();
}

각 장치는 해당 Begin 명령어를 먼저 실행하십시오. I²C 주소와 핀 공유 여부를 확인하고, bool 반환값이 false이면 배선과 전원을 점검하십시오.
