Abstract

This is a final year project report that describes about the project of Real-Time Clock Display (PART-2). This project is to implements a program for a digital clock model with LED dot matrix display which is using a PIC16F877 microcontroller and a DS1307 Real Time chip (RTC) as the main part ofthe circuitry. PART-2 involves more on PIC programming side as well as the configuration of microcontroller. The advantage of using real time chip instead of normal programming to create a digital clock is the RTC use crystal frequency count to set the time counter that will avoid count time problem. Furthermore, RTC also provides seconds, minutes, hours, day, date, month, and year information 'that initialized by writing the appropriate register bytes. The project program flow start from reading input from setting buttons, follow by data processing for i2c driving of RIC chip from a PIC microcontroller and character generation with an i2c EEPROM lastly display the output via LED dot matrix. C Language as chosen programming language to write the program.
