Description:



Information for the AVR Microcontroller hobbyist.


Contents:

Recommended Blog 4 - Vassilis Serasidis


  • This blog is belong to Mr.Vassilis Serasidis
  • It has many good project based on atmel microcontroller.
  • Some of his interesting project is :
- Generic experimental AVR board
- Infrared remote control receiver
- USB AVR In-System-Programmer
- AVR based oscilloscope
- 2 channel RF remote control
- SMS remote control
- Visual Basic & AVR serial interface

Details can be found HERE



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.
  • Then the AVR does a Analogue to digital conversion on channel 0.
  • Then transmits the results back via the serial port in ascii hex.
Details can be found HERE



Tutorial 10 - Quickstart Tutorial for ATMEL 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.
  • It's suitable and recommended for beginner microcontroller player.
Details can be found HERE


Recommended Project 9 - Inertial GPS with an ATMega 128


  • This project was conducted by the student of Cornell University.
  • This project's goal is to determine the user's position with a commercial GPS system aided by MEMS accelerometers and gyroscopes.
  • The additional MEMS sensors allow for prediction of the user's movement in between and in absence of the absolute GPS updates.
  • The primary use of this system would be for in-car GPS where velocities are relatively high (>~1 m/s).
Details can be found HERE



Recommended Blog 3 - Tutorial


  • This Blog conducted by Mr.Tiyo Avianto.
  • He explain about CodeVision AVR.
  • Due to his effort, this blog is written in Indonesian language.
Details can be found HERE



Recommended Project 8 - Build your own wireless receiver and transmitter device


  • This project used two ATMega32 microcontrollers.
  • It transmit and receive data over the USART.
Details can be found HERE



Recommended Blog 2 - Reverse Engineering of ATmega169


  • Those people at Flylogic Engineering has done a good and adorable job in reverse engineering method.
  • Below is some of their artwork.


  • Their feeling of curiosity lead them to tear down TQFP package for review.
  • Delayering the device is one of the steps in analyzing any substrate.

Recommended Project 7 - AVR Thermostat


  • This thermostat is built around an ATMega164P and a TC1047A temperature sensor.
  • It controls your furnace and air conditioner.
  • It is not programmable, although it has a clock and is capable if some additional code were written.
  • The unique feature is used of single rotary encoder, for a very simple user interface.
Details can be found HERE



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.
Details can be found HERE



Software 2 - PonyProg


  • Simple but powerful programmer .
  • Serial device programmer software with a user friendly GUI framework available for Windows95/98/ME/NT/2000/XP and Intel Linux.
  • Its purpose is reading and writing every serial device.
  • Supports I²C Bus, Microwire, SPI eeprom, the Atmel AVR and Microchip PICmicro.
  • SI-Prog is the programmer hardware interface for PonyProg.
  • With PonyProg and SI-Prog you can program Wafercard for SAT, eeprom within GSM, TV or CAR-RADIO.
  • Furthermore it can be used as a low cost starter kit for PIC and AVR.
Details can be found HERE



Recommended Project 6 - ATmega 128 Prototyping Board


  • Uses 64-pin ATmega128/1281/2561.
  • USB-serial interface via FTDI FT232RL.
  • Selectable power (USB/External/VTarget, external could be 5V or 3.3V).
  • Selectable clock source (crystal or clock from FT232RL).
  • All ports are avaiable at pinheaders.
  • Direct interface to GU300 Graphical VFD's.
  • Port D, E & F are laid out identical to the STK500.
  • Port A, C & G are in a single header, making it possible for future memory expansion.
Details can be found HERE




Recommended Project 5 - simple vga/video adapter


  • Owner of this site wanted a design that would be capable of displaying at least 15x15 characters on a VGA monitor using standard VGA frequencies.
  • The data itself is to be received by the microcontroller via its USART port.
  • All using a 16 Mhz clock for the AVR.
