Inter-Integrated Circuit (I²C) Developer Guide#

About This Guide#

This guide introduces the use of the Inter-Integrated Circuit (I²C) peripheral on the SiWx917 SoC, helping you quickly and reliably connect external devices such as sensors, EEPROMs, and power management ICs to your application.

It explains how to use the WiSeConnect SDK within Simplicity Studio IDE to configure and operate I²C on the SiWx917. Topics include initialization, configuration, low-power operation, error handling, debugging, and practical examples to accelerate your development process.

All content is based on the SiWx917 platform and validated on Silicon Labs evaluation kits and modules.

Audience#

This guide is intended for embedded developers and system designers who want to integrate I²C peripherals into their SiWx917-based applications. It assumes basic familiarity with the I²C protocol but does not require prior experience with the WiSeConnect SDK.

Purpose#

The purpose of this guide is to help you:

  • Reduce development time with clear instructions and ready-to-use examples.

  • Take advantage of SiWx917-specific features, including low-power operation.

  • Ensure robust communication with recommended practices for configuration, error handling, and debugging.

Scope#

This guide covers:

  • I²C architecture and software implementation on the SiWx917 SoC.

  • Initialization, configuration, API usage, low-power modes, error handling, and debugging of I²C peripherals.

  • Best practices for reliable and power-efficient I²C communication.
