DS1307 Real-time clock (RTC)

Device driver for DS1307 Real-time clock (RTC) based on STM32 HAL Library, What do You need?

• Any STM32 Nucleo-Board or any STM32 Microcontrollers
• STM32Cube IDE (HAL Libraries)
• Any dev-board DS1307 or your custom hardware

How to use:

• Created new project in your STM32Cube IDE
• Select your STM32 Microcontroller in my case I used a STM32F103CBTx (Blue Pill board)
• Select your preferred I2C peripheral in my case I used I2C1
• If you need to use another I2C peripheral just modify this macro DS1307_HANDLER in the file ds1307.h
• Include the source files in your project
