UART Communication

Using UART of PIC Microcontroller – MPLAB XC8

UART stands for Universal Asynchronous Receiver / Transmitter. It is a very popular serial communication interface which provides Full Duplex communication between two devices. UART uses two data lines for sending (TX) and receiving (RX) data. Ground/Reference of both devices should be made common. As the name indicates it is an asynchronous communication interface, which means that it doesn't need to send CLOCK along with data as in synchronous communications. UART is the communication interface used by our old computer's...

LED

Getting Started with PIC Microcontroller – CCS C Compiler

You are at the right place if you are a beginner to the field of microcontrollers. In this tutorial you will learn How to Blink an LED using PIC Microcontroller. PIC is a family of microcontrollers manufactured by Microchip Technology Inc. PIC stands for Peripheral Interface Controller. It is also referred to as Programmable Interface Controller or Programmable Intelligent Computer. As all other microcontrollers PIC Microcontroller can be programmed using Assembly Language. As it is little bit difficult we prefer High...

Servo Motor

Interfacing Servo Motor with PIC Microcontroller – MPLAB XC8

Servo Motor Servo Motor is an ordinary geared dc motor equipped with closed loop servo mechanism which uses position feedback to control exact angular position of the rotor. These are commonly used in robotic arms, legs etc. Servo Motors do not rotate continuously, their rotation is limited to fixed angles. Usually these motors have rotation limit from 90º to 180° and some special have limits 360° or more. Servo Motors usually have three wires. RED and BLACK wires are used to provide...

16x2 Character LCD

Interfacing LCD with PIC Microcontroller – MPLAB XC8

In this tutorial we will see How to Interface a 16x2 character LCD module with PIC 16F877A Microcontroller using MPLAB X IDE and MPLAB XC8 C Compiler. 16x2 Character LCD is a very basic and low cost LCD module which is commonly used in electronic products and projects. 16x2 means it contains 2 rows that can display 16 characters. Its other variants such as 16x1 and 16x4 are also available in the market. In these displays, each character is displayed...

Compensated Attenuator

Compensated Attenuator

An attenuator is an electronic device which reduces the power or amplitude of a signal without considerably affecting the wave shape. Thus it works in an opposite way that of an amplifier does. Attenuator provides loss (gain < 1) while an amplifier provides gain (gain > 1). A Compensated Attenuator is a simple two port network which provides a constant attenuation over a wide range of frequencies. Here I am explaining attenuators and compensation in the input of vertical deflection amplifiers used...

Push Button Switch

Using Push Button Switch – MPLAB XC8

Push Button Switch I hope that you already go through the first tutorial of MPLAB XC8, Getting Started with MPLAB XC8 - LED Blinking. In that tutorial we learn how to use an output pin by driving an LED. In this we will learn how to read an Input pin using a push button switch. We already seen that TRIS register is used to set direction of each IO pin, ie Input or Output and PORT register is used to read...

LED

Getting Started with MPLAB XC8 Compiler – LED Blinking

In this tutorial we will learn How to Blink an LED with PIC Microcontroller using MPAB XC8 Compiler. Recently Microchip released a series of development tools including MPLAB X IDE and MPAB XC Compilers. MPLAB X IDE is a software that runs on a computer intended to develop applications for Microchip's Microcontrollers and Digital Signal Controllers. It can be used with Windows, Mac and Linux Operating Systems. It is called an Integrated Development Environment as it provides comprehensive facilities to...
