• AVR Embedded Microcontroller Resources - very good AVR link page   
• AVRfreaks.net - Atmel AVR processor technical forum   
• AVR-GCC - port of the well known Gnu compiler for AVR   
• DonTronics Atmel page - lots of Atmel resources   
• Interfacing AT89C20051 using KEIL C - how to write a simple program using C language for the AT89C2051   
• Interfacing AT90S2313 using IMAGECRAFT AVR C   
   

• Programmers

• Easy-Downloader for ATMEL 89C2051/4051 - free schematic and software for building your own a device for writing intel-HEX file to the AT89C2051 and AT89C4051   
• Easy-Downloader V2.0 for ATMEL 89C51/52/55 - capable of writing intel-HEX file to a 89C51(4kB), 89C52(8kB) and 89C55(20kB)   
• Flash Microcontroller Programmer - This circuit programs the popular ATMEL 20 pin flash microcontrollers. The device is connected to the parallel port and is operated from the Assembler & Programmer software.   
• Flash Microcontroller Programmer II - This new circuit programms the ATMEL 40 pin flash microcontrollersl. The device is connected to the parallel port and is operated from the Assembler & Programmer software.   
• Fuzpol - fuzzy-logic robot control language for Atmel AVR90S8515 MCU   
• PC printer port programs AT89C51 - simple PC printer-port interface programmer can program an Atmel AT89C51 flash-based microcontroller   
   

• Circuits

• Alberto Ricci Bitti - Award-winning electronics designs based on AVR AT90S1200 and PIC Microcontrollers   
• A serial to parallel converter using the AT89C2051 - This is a basic serial to parallel converter written in 8051 assembler. This is probably a good example of the uses to which an AT89C2051 can be put - it would be hard to get a serial to parallel converter much simpler than the single 20 pin IC in this circuit. The program is meant to serve as a useful example of 8051 serial routines and other programming, whether or not you actually need a serial to parallel converter.   
• Atmel AVR Microcontroller Projects - This site is dedicated to my AVR ATMEL microcontroller projects. Here you will find schematics and board-layouts in Eagle 4.01 format, also the program-code, part-lists and pictures of the projects. At the moment there are five projects: LCD interface, running LED light a digital LCD thermometer a LED thermometer and a stepper motor driver.   
• C-52 EValuation Board - a low-cost learning board C-52 EVB for studying Assembly and C language programing   
• Electronic circuits, based on AVR microcontrollers - On this site, you will find many circuits based on AVR microcontrollers from Atmel. The purpose of this site is to learn all of you, that you want to follow the technology of electronics, to work with this litle powerful things that called microcontrollers. Circuits like, universal USB interface with AT90S2313, SMS remote control, programable LCD counter with memory backup, telecard reader, 128x64 dot-matrix lcd driver, RCEN fuse bit programmer and more. This Web site contain AVR forum with Greek and English sections.   
• HSETI PCB - small simple application for the Atmel AT89C2051 microprocessor
• Kierroslukumittari -This is a car motor speed meter using AT89C1051. The description text is in Finnish.   
• Micro based PIR to IR remote converter - an automatic system which starts the VCR recording and stops four minutes after the last PIR event   
• Video DVM - digital multimeter circuit with video output   
   

• Software

• AVR Mini Threads: a nanoKernel for the AT90S1200 - A powerful way to do a cooperative multitasking with the AVR AT90S1200. You can do a "wait" to go sleep and wait for a signal, or send a signal to wake up another thread.
