Real Time Clock with alarm support and tamper protection.
Module Operation
The Real Time Clock (RTC_C) API provides a set of functions for using the SDK L RTC_C modules. Functions are provided to calibrate the clock, initialize the RTC_C modules in Calendar mode, and setup conditions for, and enable, interrupts for the RTC_C modules.
The RTC_C module provides the ability to keep track of the current time and date in calendar mode.
The RTC_C module generates multiple interrupts. There are 2 interrupts that can be defined in calendar mode, and 1 interrupt in counter mode for counter overflow, as well as an interrupt for each prescaler.
Programming Example
The DriverLib package contains a variety of different code examples that demonstrate the usage of the RTC_C module. These code examples are accessible under the examples/ folder of the SDK release as well as through TI Resource Explorer if using Code Composer Studio. These code examples provide a comprehensive list of use cases as well as practical applications involving each module.
Below is a very brief code example showing how to configure the RTC_C module and create a calendar event.
The following is the configuration structure that sets the date:
