Introduction
In this post, you will learn how to test RTC (Real Time Clock) on M-Duino PLUS industrial controller Arduino version.
Software
Remember that the RTC uses the I2C protocol for its communication (Check switches for correct operation)
//RTC library example // by Industrial Shields #include <RTC.h> const int YEAR = 2018; const int MONTH = 3; const int DAY = 28; const int HOUR = 13; const int MINUTE = 24; const int SECOND = 25; //const int TIME = 1522242547; //UNIX timestamp (spent seconds since Jan 1 1970 00:00:00) //////////////////////////////////////////////////////////////////////////////////////////////////// void setup() { Serial.begin(9600L); Serial.println("Configuring RTC: "); Serial.println(); RTC.setYear(YEAR); //sets year RTC.setMonth(MONTH); //sets month RTC.setMonthDay(DAY); //sets day RTC.setHour(HOUR); //sets hour RTC.setMinute(MINUTE); //sets minute RTC.setSecond(SECOND); //sets second //RTC.setTime(TIME); //sets UNIX timestamp if(!RTC.write()){ //RTC.write writes in the RTC memory all that has been set Serial.println("Write date error: Are the switches well placed?"); } } //////////////////////////////////////////////////////////////////////////////////////////////////// void loop() { if (!RTC.read()) { Serial.println("Read date error: is time set?"); } else { Serial.print("Time: "); Serial.print(RTC.getYear()); Serial.print("-"); Serial.print(RTC.getMonth()); Serial.print("-"); Serial.print(RTC.getMonthDay()); Serial.print(" "); Serial.print(RTC.getHour()); Serial.print(":"); Serial.print(RTC.getMinute()); Serial.print(":"); Serial.print(RTC.getSecond()); Serial.print(" ("); Serial.print(RTC.getTime()); Serial.println(")"); } delay(1000); }

By following these steps carefully, you will be able to achieve the use of the RTC using Industrial Shields equipment (programmable logic controllers and Panel PCs).
