The Real-Time Clock (RTC)
In this chapter, we will explore the Real-Time Clock (RTC) peripheral, an essential component for timekeeping in embedded systems. This peripheral is crucial for applications that require accurate time and date maintenance, making it fundamental for a wide range of embedded applications.
We will start by introducing RTCs and understanding how they function. Following this, we will delve into the STM32 RTC module, examining its features and capabilities. Next, we will analyze the relevant registers from the STM32 reference manual, providing a detailed understanding of the configuration and operation of the RTC. Finally, we will apply this knowledge to develop an RTC driver, enabling precise timekeeping in your embedded projects.
In this chapter, we will cover the following main topics:
- Understanding RTCs
- The STM32 RTC module
- Some key RTC registers
- Developing the RTC driver
By the end of this chapter, you will have a solid understanding...
