This is a platform agnostic Rust driver for the DS1307 real-time clock,
based on the
This driver allows you to:
- Read and set date and time in 12-hour and 24-hour format. See:
- Enable and disable the real-time clock. See:
- Read and write user RAM. See:
- Control square-wave output. See:
The DS1307 serial real-time clock (RTC) is a low-power, full binary-coded decimal (BCD) clock/calendar plus 56 bytes of NV SRAM. Address and data are transferred serially through an I2C, bidirectional bus.
The 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 AM/PM indicator.
The DS1307 has a built-in power-sense circuit that detects power failures and automatically switches to the backup supply. Timekeeping operation continues while the part operates from the backup supply.
