DS1307

Real-time clock with an I²C bus.

Tutorial / documentation

Modules & interfaces

First tests with DS1307

  1. Identify the exact DS1307 variant, package and manufacturer documentation.
  2. Identify power, ground and signal pins in the documentation. Assemble the circuit with power disconnected.
  3. Follow the manufacturer’s evaluation circuit. Use a current-limited low-voltage supply and the recommended logic levels.
  4. Mesurez les signaux d’entrée et de sortie. Comparez leur comportement à la fonction : horloge temps réel avec bus i²c.
