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 Communication I2C is a master slave protocol. It means that devices connected to I2C bus will be either master or slave. The...

PWM - Pulse Width Modulation

Generating PWM with PIC Microcontroller – MPLAB XC8

Pulse Width Modulation (PWM) is the one of the simple and most commonly used technique to produce analog voltages from digital signals. It has a wide variety of applications such as Digital to Analog Converter (DAC), DC Motor Speed Control, Sine Wave Inverters, Brightness control etc. PWM signals are ON - OFF signals (HIGH or LOW) (hence the name Pulse) whose HIGH or ON duration is changed (hence Width Modulation) in accordance with our requirements. The fraction of time period for...
