It communicates with a microprocessor via a simple serial interface. The real-time clock/calendar provides seconds, minutes, hours, day, date, month, and year information. The end of the month date is automatically adjusted for months with fewer than 31 days, including corrections for leap year. The clock operates in either the 24-hour or 12-hour format with an AM/PM indicator.Interfacing the DS1302 with a microprocessor is simplified by using synchronous serial communication. Only three wires are required to communicate with the clock/RAM: CE, I/O (data line), and SCLK (serial clock). Data can be transferred to and from the clock/RAM 1 byte at a time or in a burst of up to 31 bytes. The DS1302 is designed to operate on very low power and retain data and clock information on less than 1μW.\n\nLibDriver DS1302 is a full function driver of ds1302 launched by LibDriver.It provides time reading, ram reading or writing and other functions. LibDriver is MISRA compliant.\n\n### Table of Contents\n\n  - [Instruction](#Instruction)\n  - [Install](#Install)\n  - [Usage](#Usage)\n    - [example basic](#example-basic)\n    - [example advance](#example-advance)\n  - [Document](#Document)\n  - [Contributing](#Contributing)\n  - [License](#License)\n  - [Contact Us](#Contact-Us)\n\n### Instruction\n\n/src includes LibDriver DS1302 source files.\n\n/interface includes LibDriver DS1302 GPIO platform independent template.\n\n/test includes LibDriver DS1302 driver test code and this code can test the chip necessary function simply.\n\n/example includes LibDriver DS1302 sample code.\n\n/doc includes LibDriver DS1302 offline document.\n\n/datasheet includes DS1302 datasheet.\n\n/project includes the common Linux and MCU development board sample code.
