Handling the Digital Input Output in AVR Micro Controllers 1

Handling the Digital Input Output in AVR Micro Controllers

I have already discussed about a few chapters necessary to get into AVR programming. Now this is the first article that deals with programming.  Let us start with the basics. Digital input output (I/O) is the basic feature supported by  AVR micro controller. To facilitate digital input output, three registers are associated with each port

Standard Library String Formatting for AVR

Standard Library & String Formatting for AVR

Here in this article, I am planning to brief you through the Standard library of AVR-GCC. By the term “Standard Library” we mean the “Standard header” files like “stdio.h”, we commonly see in C programming language. Have you ever used String Formatting in ANSI C? Did you use Standard library functions? If you are familiar
