<examples/I2C/Wire/RTC-RV3032>

Supported Platforms: SOMRT1061 with DEV-SOMRT1061

External Real-Time Clock example using the Micro Crystal RV3032 RTC connected to the I2C bus, such as with the SOMRT1061-200IR on the DEV-SOMRT1061 development board containing the RV3032.

The example uses the Wire interface class for I2C operation, and requires an Internet connection to obtain the current time with NTP.

Creates a NtpClientServlet instance to run as a background task in the configuration server.
Reads the time stored in the RTC
Compares the two values and sets the RTC to the NTP time if there is a difference of 2 minutes or more.

There are multiple I2C peripherals on each NetBurner platform as indicated in the tables below. The first

line is the default.
