Programming the STM32 MC. Lesson 150. LL. I2C. Connecting an external EEPROM. Part 3
In this lesson, we will continue working with the LL library (low-layer drivers) and try to work with the I2C bus. We will connect the EEPROM AT24C32 chip, located in the clock module, to this bus.
We will use the same controller - STM32F103.
In this part of the lesson, we will write functions for writing and reading data on the I2C bus and test our knowledge in practice, and we will also try to increase the data exchange speed on I2C.
