Detailed Configuration of an Intelligent Lock System Based on STM32: A Case Study of AT24C04 (Part 1)
1. The Relationship Between I²C Timing and AT24Cxx Driver AT24Cxx (24C02/04/08/16…) is an EEPROM storage chip that communicates with the MCU via the I²C bus.The essence of I²C is: Using two wires (SCL, SDA) to read and write data according to a fixed timing. Signal Line Meaning SCL Clock line, controlled by the master (MCU) … Read more
