Project Clock and calendar


 The solar project is planned to display the time and date.



The solar project is planned to display the time and date.
At the time of this project is the use of micro-mega16.
RTC is one of the advantages of microcontrollers AVR microcontroller on the other. In order to enhance the accuracy and separation of micro system clock RTC, external clock, this section must be provided by a single crystal (of 32768 Hz). He also reduce system size and precision performance of this program is that the program works is very important. Notably RTC system works 24 hours a day, and the operation of micro uses timer2.
Registration in the program from 1388 to 1400 AD and supports. The exact date of the order of 31 days during leap years and has been. Variables day, month, and year, and the eprom type switching power retain their value.

Algorithm is written in a way
The part of the user in the settings to leave after a specific time values ​​are stored in the application returns to the main core.
