Webb17 mars 2016 · In this tutorial, I will explain about I2C protocol and how to use it on STM32F103 microcontroller. I2C (Inter-Integrated Circuit) or sometimes called TWI (Two Wire Interface) is a synchronous serial protocol that only need 2 wire for communication. These wire are SCL for clock line and SDA for data line. Using I2C bus, you… WebbYou said that you send the slave address and the address in the eeprom using DMA so the ADDR flag will not be reset -> that is why the line remains low (stretched because ADDR is set) and consequently you will not be able to generate a START. The DMA requests (when enabled) are generated only for data transfer.
