Set Up RTC in STM32 & Display Time on LCD (HAL + CubeMX)

Learn how to configure and use the **internal RTC (Real-Time Clock)** in STM32 microcontrollers using STM32CubeMX and HAL library. This tutorial covers everything from enabling RTC in CubeMX, setting the clock source, writing HAL code for date and time, and even handling low-power modes. We’ll also explore RTC alarms, backup registers, and practical use cases in embedded systems. 🔽 **Download the complete project code** 👉 (https://controllerstech.com/internal-rtc-in-stm32/) 📺 **Related STM32 Tutorials** *Interface LCD16x2 with STM32 using I2C →(https://youtu.be/rfRJGfK2t-A) * STM32 External RTC with DS3231 →(https://youtu.be/LBD7noDBnlc) #STM32 #RTCTutorial #STM32CubeMX #EmbeddedSystems #Controllerstech #MicrocontrollerProgramming #STM32Projects
