I²C – Inter-Integrated Circuit

I²C or I2C is an abbreviation of Inter-Integrated Circuit, a serial communication protocol made by Philips Semiconductor (now it is NXP Semiconductor). It is created with an intention of communication between chips reside on the same Printed Circuit Board (PCB). It is usually used to interface slow speed ICs to processor or microcontroller. It is a master-slave protocol, usually a processor or microcontroller is the master and other chips like RTC, Temperature Sensor, EEPROM will be the slave. We [...]

I²C Communication with PIC Microcontroller – MPLAB XC8

I2C or IIC or I2C stands for Inter-Integrated Circuit. It is a very popular multi-master, multi-slave serial communication interface developed by Philips. I2C uses two bidirectional open drain data lines, Serial Data (SDA) and Serial Clock (SCL) with pull up resistors as shown below. Unlike UART, you can connect and communicate to multiple devices using the same I2C bus.I2C CommunicationI2C is a master slave protocol. It means that devices connected to I2C bus will be either master or slave. The master is [...]
