System Real-Time Clock (SYSRTC) API Reference#

This section provides reference information for the System Real-Time Clock (SYSRTC) application programming interfaces (APIs) available on the SiWx917 platform.

SYSRTC enables developers to manage real-time counters for precise timekeeping, event scheduling, and timestamp handling in embedded applications.

The following topics describe the public APIs, callback mechanisms, and notification interfaces, with direct links to detailed documentation and practical examples.

API Reference#

The SYSRTC API reference includes detailed descriptions of functions, parameters, return values, and usage guidelines. Developers can use these APIs to integrate SYSRTC features into their applications effectively.

For complete technical details, see the SiWx917 SYSRTC API Reference.

Public APIs#

Public APIs provide direct access to SYSRTC functionality. Use these APIs to configure, control, and read values from the System Real-Time Counter.

For implementation guidance, see the SYSRTC Example.

Callback and Notification APIs#

SYSRTC supports callbacks and notifications to simplify event handling. Callbacks enable your application to respond automatically to timer events, alarms, or counter thresholds without continuous polling.

For implementation details, see Registering Event Callbacks.
