38+ Rtc Ds1307 Pinout PNG. Data between the cpu and rtc ic is exchanged only though the i2c protocol. Every real time applications need one rtc chip.
Interfacing RTC with Microcontroller - EmbedJournal from embedjournal.com Ds1307 rtc module has all onboard components which are required for the correct functionality of a ds3107 chip. Address and data are transferred serially through an i2c, bidirectional bus. Address and data are transferred serially through an i2c, bidirectional bus.
A typical application circuit for the ds1307 from ds1307 this pin also requires a pull up resistor.
See the timertc example sketches privided with the time library download for usage. Using this module is simple, rtc part. Address and data are transferred serially through an i2c, bidirectional bus. See the timertc example sketches privided with the time library download for usage.
