Quickstart Tutorial for AVR Microcontrollers

                                                                                                                                         

• The goal of this tutorial is to get you up and running as quickly as possible.
• You can get to exploring and modifying on your own without having to fiddle with hardware, software, parts, or settings.

Tutorial 11 - Using the AVR Analog-Digital Converter

• This tutorial will show on how to do an analog-digital conversion with AVR microcontroller.
• AVR will receive data from the it's serial port.

Tutorial 9 - Example using the two-wire interface (TWI)

• The two-wire interface consists of two signal lines named SDA (serial data) and SCL (serial clock).
• All devices participating in the bus are connected together.
• The pullups must be small enough to recharge the line capacity in short enough time compared to the desired maximal clock frequency.

Tutorial 8 - Tutorial for learning assembly language

• Tutorial for using AVR single chip processors with practical examples.
• This version are excellent for homebrewing every kind of processor-driven electronics.
• The only problem is that assembly has to be learned in order to program these devices.
• These pages are for beginners and help in learning the first steps.

Tutorial 6 - Programming an Atmel AVR

• The following tutorial introduces programming of your AVR microcontroller using In System Programming (ISP).
  
• This programming technique allows you to program the eeprom and flash memories of your chip while in circuit.
  
• This removes the requirement of placing your chip in a dedicated programmer every time for programming.
• You will need an ISP compatible programmer.
• These come in both parallel and serial versions and can be bought from atmel and many other people.

Tutorial 5 - Linux Atmel AVR Tutorial

• The Atmel AVR family is a set of powerful microcontrollers that were designed to be used with the C programming language.
• You can now compile a C program for the AVRs with gcc, then load the program onto the chip using an inexpensive programmer and free tools.
• For Linux users who want to work on digital electronics, robotics, and automation, these chips are the way to go.
• This page is a step-by-step tutorial that presents the simplest, cheapest way to start experimenting with AVRs.

Tutorial 4 - AVR - Input / Output

• Tutorial on how to use AVR microcontroller i/o pins.
• Overall will discuss about input , processing it and generating output.
• Understand i/o registers and their correct settings is indispensable part while learning to program any microcontroller.
• This tutorial will show how to use AVR ports and actually code for writing/reading data to/from port pins.
• Really good understanding for beginners.
