Briefing- I2C
INTER INTEGRATED CONTROLLER Developed by Philips SC (low cost, simple interface, easy to use, used for simple interconnect). Used to send data between microcontrollers and peripherals like EEPROM, RTC, Sensors, SD Card, LCD, RFID card module, consumer electronics. It is a serial communication protocol. Maximum speed is 5Mbps. How I2C come into existence? It is a simple bus having 2 wires for data communication. SCL- Clock Signal Line (serial clock used for all data communication) SDA- Data Signal Line (serial data) (by default initially both should be high as it is pull-up connected to Vcc ) It is Half Duplex (either master or slave can send data at the same time through SDA Line). Either read or write operation possible via bus at a single time. Master- The one which initializes a transfer, greater clock signal, terminate the transfer. (Slave cannot do these things) (Master or slave can put the data on SDA line) It is normally used for short distance communication means commu...
