Interfacing of LED wiht AVR - ATMega16

Hi friends, Today I am going to tell you, how can you interface an LED with AVR (ATMega16). Here I am using only one AVR microcontroller ATMega16, one register(10K), one capacitor(16uF/25v), One push button switch, Led BAR Green in stead of 8 led's, power supply of +5v and -5v. Make the circuit as in diagram. Below is the circuits diagram and code for blink of the led will given below:

Burning hex files using USBasp

AVRDude is excellent program for burning hex code into microcontroller. USBasp is awesome USB based programmer for the AVR. In this tutorial we will see how to use AVRdude for burning hex files into AVR microcontroller using USBasp.

AVRdude is not readily available for windows installation. Windows version of AVRdude is bundled with WinAVR compiler. Before we start : Download WinAVR from here.

USBasp driver installation

In this post we will see how to install windows driver for USBasp. Steps explained below are applicable for WindowsXP:

Download driver:
If you don’t have driver, windows drivers for USBasp can be downloaded from:

Introduction to AVR

AVR Tutorial

AVR microcontrollers from ATMEL are very good choice for designing mid-range embedded systems.They are 8Bit RISC controllers. They come in many verities and most of them gives 16MIPS (Mega Instructions Per Seconds) throughput at 16MHz . 

Unlike most of the popular PIC microcontrollers, AVRs have powerful instruction set, most executing in 1 cycle. Recently ATMEL has introduces some new controllers with speed upto 20MHz and USB support.

About AVR Programmer

This simple AVR Programmer will allow you to painlessly transfer hex programs to most ATMEL AVR microcontrollers without sacrificing your budget and time. It is more reliable than most other simple AVR programmers available out there and can be built in very short amount of time.

AVR programmer consists of in-circuit serial programmer (dongle) and small pcb with a DIP socket where you can fit your microcontroller and have it quickly programmed.
