Timer / Counter Module – A Controller Independent Guide

timer

In this post I intend to provide a standalone, controller independent, Guide to Timer / Counter Module in Microcontrollers. The concepts explained are not associated with any one particular controller which might not be useful for all readers. To an extent this is an independent post but little exposure to Interrupts and how they work is a prerequisite, which may not be within the scope of this post. But otherwise this post should have everything you need to know about …

Interfacing RTC with Microcontroller

Have you ever wondered how your PC and phones keep track of time even when the device is turned OFF? Well there is a Real Time Clock (RTC) that is kept powered even is the device is turned OFF. Once the device is turned ON and connected to the internet the device connects to a NTP server (Network Time Protocol) and updates the time and date. This post is intended to give a little insight over these RTCs and their interface with mid-range 8-bit …

I2C Protocol (2-Wire Interface) in a nut shell

The I2C protocol also known as the two wire interface is a simple serial communication protocol that uses just two pins of a microcontroller namely SCL (serial clock) and SDA (serial data). This is a very popular protocol cat can be used to address a large number of slave devices that are connected to the same bus. This protocol comes in handy when there is scarcity on available pins in the microcontroller. Each slave device has a slave address or names for which they respond …

Getting started with Embedded Systems

embedded system

Hey everyone, I have planned to document all the small electronics projects that I do in my free time so that it would be of some use to all the beginners of the same interest as mine. I may not be regular in posting new stuffs, but I will try my level the best to post the most optimized content of what I have  done. When I was a beginner, I found many blogs really useful, which actually made my learning curve smooth. I am no …
