Background        “Hello World” is a C program written by Dennis Ritchie(The Inventor of C programming Language) in his book The C Programming Language to showcase the capabilities of the C language to print a string “Hello World”. In this blog we will tweak this famous program a bit and display “Hello World” message on a 20x4 LCD display. The IO Problem with MCUs!!!        As explained in key...

“Unfortunately, no one can be told what The Matrix is. You’ll have to see it for yourself.” ― Morpheus        for this blog we could change it to something more meaningful like below :) “Unfortunately, no one can be told what The Matrix Keyboard is. You’ll have to Do it for yourself, and learn.” Sensing Inputs        MCU interacts with real world using sensors and actuators. In this blog...

USBasp - Open source AVR programmer Construction Programmer options        To tinker with any microcontroller, first step is to transfer/program the software to the microcontroller. There are different ways of doing this, listed as below options. Silicon manufacturer programmers/debuggers: High End - ATMEL-ICE Mid range - Pickit4 Low cost - Snap Bootloader...

HW Platform to be used Microchip(formerly ATMEL) 328P Controller       This post is yet another blinky program on popular Microchip ATMEGA 328p micro controller. We will be using Arduino nano board for our experiment. Since the HW is readily available we can concentrate on writing our first program for blinking the LED! Software development environment for blinky       We will be using Bare ...
