How to connect STM32F429I-DISC1 board to DS1307 using I2C
On the STM32F429 board, there is one I2c extension connector. This connector has eight pins. Which is used to connect to other I2C peripherals such as RTC, EEPROM and other microcontrollers etc. In the hardware schematics, it is labelled as ACP/RF E2P connector. The I2C3 SDA and SCL lines are pulled up via a 4.7…

How to use DS1307 RTC with ATmega328PB via I2C in Microchip Studio
The DS1307 Real Time Clock uses I2c communication lines to connect with the microcontroller. I2C uses two lines commonly known as Serial Data/Address or SDA and Serial Clock Line or SCL. The two lines SDA and SCL are standardised and they are implemented using either an open collector or open drain configuration. What this means…
