The STM32 RTC module
In this section, we will explore the RTC module in the STM32F4 microcontroller family. Let’s start by looking at its features.
The main features of the STM32F4 RTC module
The STM32F4 RTC module is like the Swiss Army knife of timekeeping, offering a rich set of features designed to meet the needs of numerous applications. Here are some of the standout features:
- Calendar with sub-seconds: The RTC module doesn’t just keep track of hours, minutes, and seconds; it also maintains sub-second accuracy. This is particularly useful for applications that require precise time measurements.
- Alarm functionality: Imagine that you have two alarm clocks within your microcontroller. The STM32F4 RTC module provides two programmable alarms, Alarm A and Alarm B, which can trigger events at specific times. This is perfect for tasks that need to be performed at regular intervals or at a specific time of day.
- Low power consumption: One of the biggest...
