Quick start guide for RTC32 driver

This is the quick start guide for the RTC32 driver, with step-by-step instructions on how to configure and use the drivers in a selection of use cases.

The use cases contain several code fragments. The code fragments in the steps for setup can be copied into a custom initialization function, while the steps for usage can be copied into, e.g., the main application function.

Basic use case

Setup steps

Example code

Add to the initialization code:

sysclk_init();
rtc_init();

Workflow

1. Ensure that conf_rtc.h is present for the driver.

   • Note

     This configuration file is used by the driver and should not be included by the user.

2. Initialize system clock:

   • sysclk_init(); 

3. Call RTC32 driver's own init function to initialize the 32kHz oscillator and RTC32:

   • rtc_init(); 

Usage steps

Example code

Add to, e.g., main loop in application C-file:

rtc_get_time();

Workflow

1. Get current time of the RTC32:

   • rtc_get_time();
