I2C device setup

The next step is to check whether the time clock is synchronized with RTC time. Here we define the RTC local:

sudo nano /etc/rc.local

Add the following lines to the file as we declare the new device and the path we configure:

echo ds1307 0x68 > /sys/class/i2c-adapter/i2c-1/new_device

The following command will start up the RTC:

hwclock -s

After this command, reboot the Pi. You will see the following screen, which means that the RTC is configured and ready to work:
