This application note aims to support the use of the I2C interface on Elara and Erinome GNSS modules. I2C interface is available in these modules as an alternative to UART. The GNSS module functions as Multi-Master.
The first part of the document describes the basics of I2C communication. This technical background information helps to understand the rest of the document. It includes understanding the different roles and phases in the communication, addressing of the bus subscriber and data structure.
The recommended I2C communication hardware setup is described in detail in Chapter 3. The same setup can be used for Elara-I, Elara-II, and Erinome-II modules, operating with 1.8 V power supply. A slightly different setup is required for Erinome-I, operating with 3.3 V power supply.
