Configurer I2C sur votre Pi
You'll also need to set up i2c on your Pi, to do so, run sudo raspi-config and under Advanced select I2C and turn it on.
Reboot once you've done that with sudo reboot
Vérifier le câblage
Verify your wiring by running
sudo apt-get install python-smbus i2c-tools
to install the helper software and then sudo i2cdetect -y 1 at the command line, you should see ID #68 show up - that's the address of the DS1307, PCF8523 or DS3231!
If you have a much older Pi 1, you will have to run sudo i2cdetect -y 0 as the I2C bus address changed from 0 to 1
