Setting up the DS3231 RTC
DS3231 RTC Datasheet: https://datasheets.maximintegrated.com/en/ds/DS3231.pdf Insert a coin cell battery into DS3231. Either a CR2032 or LI2032 coin cell battery will work. Insert DS3231 module into the Power Logger PCB at J5.
Download the Drivers
The ds3231.h library can be downloaded from https://github.com/rodan/ds3231. Create a folder in Documents called Power-Fail-logger. Download and Save ds3231-master.zip to that folder. Install the Zip file by clicking on the Sketch Tab in the Arduino IDE. Select Include library. Select Add .ZIP Library... Ensure sure you have added these two libraries to the Arduino environment. Wire.h ds3231.h
Validate the libraries are installed
Click the Sketch Tab Select Include library. The libraries will be listed Arduino libraries (Wire) Contributed Libraries. (ds3231-master)
To Set the date and time use the follow program and paste in the Arduino IDE.
// DS3231-Set-Time-Date.ino //This code can be found here:https://github.com/rodan/ds3231 #include <Wire.h> //Make sure you have added this library to the Arduino environment #include <ds3231.h> //Make sure you have added this library to the Arduino environment struct ts t; void setup() { Serial.begin(9600); Wire.begin(); DS3231_init(DS3231_CONTROL_INTCN); /*---------------------------------------------------------------------------- In order to synchronize your clock module, insert timetable values below ! ----------------------------------------------------------------------------*/ t.hour=20; //Set the hour in military time to your current time. t.min=40; //Set the minutes. t.sec=0; //No need to change t.mday=11; //Set the Day t.mon=4; //Set the Month t.year=2021; //Set the Year DS3231_set(t); //Comment this line out after setting RTC with time & date to validate } void loop() { DS3231_get(&t); Serial.print("Date : "); Serial.print(t.mon); Serial.print("/"); Serial.print(t.mday); Serial.print("/"); Serial.print(t.year); Serial.print("\t Hour : "); Serial.print(t.hour); Serial.print(":"); Serial.println(t.min); Serial.print(":"); Serial.println(t.sec); delay(60000); } void print2digits(int number){ if (number >= 0 && number < 10) { Serial.write ('0'); } Serial.print(number); }
Set up Programmer
Connect the USBTinyISP to the AVR-ISP-6 pin header J7 on the Power Fail Logger PCB. In the Arduino IDE click on Tools Tab - Select Programmer then select USBTinyISP.
Select correct target board
In the Arduino IDE click on Tools Tab - Select Board then select the Arduino Uno.
Connect Serial Port to the RS232 Port
Plug into your laptop USB port the Prolific USB-to-Serial Comm Port Connect the Prolific USB-to-Serial Comm Port to the RS232 Port on the Power Fail Board Connect the TX, RX, and Ground Pins to J4. Prolific J4 Power Logger TX - RX RX - TX GND - GND Use Windows Device Manager to validate which Comm Port is used. You will need this later. In the Arduino IDE click on Tools Tab - Select Port then select the Prolific Port (Example Comm6).
Flash the Microcontroller with DS3231-Set-Time-Date Program
Paste the above program DS3231-Set-Time-Date.ino into the Arduino IDE. After changing the time stamp in the program to match your current time do the following: In the Arduino IDE click on Sketch Tab - Select Upload Using Programmer
Validate the clock is set
After program has uploaded go back and comment out the DS3231_set(t); statement. Validate by reprograming the board with that line commented out. Use the same programming steps as stated above.
In the Arduino IDE click on Tools Tab - Select Serial Monitor
Once the program has finished loading hit the Reset button on the Power Fail Logger Board. You should see the correct time and date display in the Serial Monitor. It will update and display the time once a minute
