Interfacing LCD with CloudX Board

To have a good relationship between human world and machine world, display units plays a vital part. Displays allows us to know what’s happening in a device like the voltage, temperature, present status of the device and even device fault detection etc. LCD's have a very wide application in embedded systems and it is more preferred than seven segment displays. Alphanumeric LCDs are most commonly used in embedded projects since it is commonly available and easy to use. 16x2 LCD...

Getting Started with CloudX Development Board

CloudX M633 is one of the popular PIC based microcontroller development board designed by ByteHub Embedded, it comes with over 500 library functions which makes it very easy for beginners to start with embedded systems. In this tutorial we will see how to write our first "Hello World" program to blink an LED using the popular CloudX M633 (PIC16F877A chip) development board. CloudX - PIC Microcontroller Development Board and SoftCard Components Required CloudX Microcontroller Board and SoftCard Light Emitting Diode (LED) ...

Home Automation using Bluetooth and Mobile App

Technology is a never ending process. To be able to design a product using the current technology that will be beneficial to the lives of others is a huge contribution to the community. Generally in today’s modern world human beings are addicted to using modern equipment. So here we can perform home automation by using an Android App and Bluetooth as a wireless communication medium. Home automation not only refers to reduce human efforts but also energy efficiency and time...

Using ADC of PIC Microcontroller – MPLAB XC8

In this tutorial we will learn, how to use the ADC module of a PIC Microcontroller using MPLAB XC8 compiler. For demonstration we will use the commonly available PIC 16F877A microcontroller. Every physical quantity found in nature like temperature, humidity, pressure, force is analog. We need to convert these analog quantities to digital to process it using a digital computer or a microcontroller. This is done by using Analog to Digital Converters. An Analog to Digital Converter or ADC is a...

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...

Custom Characters on LCD using PIC – MikroC

I hope that you already go through our tutorial, Interfacing Character LCD with PIC Microcontroller - MicroC Pro. These character based LCDs are commonly made using HD44780 compatible controllers. It allows us to define 8 custom characters in addition to the standard pre-programmed characters. In this tutorial we will learn to define our own custom characters using MikroC compiler. DDRAM, CGROM and CGRAM CGROM - Character Generator ROM This is the memory which holds 5x8 or 5x10 dot patterns of predefined characters...

Interfacing LCD with PIC Microcontroller – CCS C

In this tutorial we will see How to interface a 16x2 character LCD Module with PIC 16F877A Microcontroller using CCS C Compiler. 16x2 character LCD is a very commonly used LCD module in electronic projects and products. 16x2 means it can display 2 rows of 16 characters. It is a very basic and low cost module. Its other variants such as 16x1, 20x4 are available in the market. In these displays each character is displayed using 5x8 or 5x10...
