The STM32F4 I2C peripherals

Depending on the specific model of STM32F4 you are working with, you can typically find up to three I2C peripherals labeled I2C1, I2C2, and I2C3. These peripherals enable the microcontroller to communicate with I2C-compatible devices using the standard two-wire interface.

The I2C peripherals in STM32F4 microcontrollers come packed with features that enhance their versatility and performance:

Multi-master and multi-slave capabilities: Each I2C peripheral can operate as both master and slave, supporting multiple master configurations where more than one master device can control the bus
Standard, fast, and fast mode plus: The peripherals support multiple speed modes, including standard mode (100 kHz), fast mode (400 kHz), and fast mode plus (1 MHz), allowing for flexibility in communication speed
10-bit addressing: In addition to standard 7-bit addressing, the I2C peripherals also support 10-bit addressing, enabling communication with a...
