Experimenting the AT90S8535 with Code Vision AVR C Compiler

Introduction The ISP (In System Programmable) of the AVR chips provides a very simpleand very cheap for hobbyist to learn and build application with AVR chips.I have got the evaluation version of CodeVisionAVR,from my friend. The CodeVision is an IDE for AVR chips having built-insoftware for STK200 compatible programmer. After compiling the source programin C, […]

AVR Thermometer using AT90S2313 microcontroller

Introduction I bought the LED module from BanMor’ last week, just 30Baht. The moduleprovide a prewired multiplex of 4-digit common anode LED, that’s great.See the soldering pad of these signal in the 1st picture below. I thought,my friend gave me the AT90S2313 chip, and with a simple homemade ISP cableand a free software AVR ISP

Signal Microcontroller Simulator using AT90S8515

Introduction: The purpose of this project was to extend the Mixed Signal AVR simulator written in Fall 02 so that any single-issue microprocessor could be included in the simulation environment rather than limiting the simulations to systems based around ATMEL AT90S8515 series microcontrollers. In order to achieve this goal, a general architectural description language (ADL)

Air-Mouse using ATmega32 microcontroller

I. Introduction The Cornell University Airmouse Initiative is a motion sensing glove with buttons on it that plugs into your computer to function as a mouse. Many tasks that are performed on the computer require the use of both a keyboard on the mouse, and many people find it frustrating and awkward to have to

kaOS operating system and loader using ATmega32

Introduction We have created a real-time, multithreaded, preemptive operating system called kaOS for the Atmel Mega32 microcontroller, which loads and executes programs from a Secure Digital or MMC card.We wrote this OS and created the SD/MMC card reader as a final project for Cornell’s ECE 476 class taught by Professor Bruce Land.  Our reason for

RFID security system using ATmega32 microcontroller

Introduction and Motivations: For our final project, we designed and built (and exhaustively tested) an RFID-based proximity security system for use with Cornell Identification cards, which have been RFID-embedded since fall of 2003. The idea for this project was sort of spawned from our general interest in RFID technologies and the near-simultaneous occurance of Lab

The Reflow Soldering Oven with LCD Display using ATmega32

Introduction Our project consists of making a reflow soldering device using a normal toaster oven with a graphical LCD display for control and GUI. Soldering is an important and difficult task for custom printed circuit board design especially for integrated circuits that come as chip packages that are impossible to solder by hand. This is

Self-powered solar data logger using ATmega32

Introduction: My project is a self-powered solar data logger. Put out in the sunlight, it will measure the light level and log this to memory to be later downloaded to a computer. The system is powered by a small solar panel and battery. Summary: The solar logger I built uses a photodiode to measure the

Wall of Pong using ATmega32 microcontroller

Wall of Pong is a fast-moving, interactive, laser-based pong game playable on any flat surface. The system uses a digitally controlled laser projection platform to draw a pong ball onto any flat surface. This allows for a large playing area that can be set up almost anywhere. Hand held paddles with embedded sensors are given
