it is very difficult to bootload Atmega chips when you don’t have proper knowledge about device signature ! each chips are associated with its own Signature.at the beginning I found very difficult in uploading bootloader file to Atmega 328pu and Atmega 328p-pu , although their are many different methods are already available in Internet ,it […]

One of the relatively unexplored topics in this week’s lecture was USB, the ubiquitous protocol that allows computers to communicate with peripheral devices (containing microcontrollers). Creating a USB device allows any computer to talk to it without the specialized software and hardware we’ve been using so far. For these two weeks, I decided to understand

This is the second part of my USB tutorial for ATtiny2313 and V-USB library. In the first part we learned how to get 3.3V from USB to power our circuits. In this part, we will expand our setup with following parts: Larger breadboard and additional jumper wires ATtiny2313 12 MHz crystal oscillator Two 27 pF ceramic capacitors

Introduction For our ECE 476 Final Project, we have built an intelligent, wearable pedometer. This wireless pedometer can calculate many useful statistics such as the number of steps a user has taken, the distance and the speed the person has walked/run, as well as the number of calories the person has burned. This information is

Overview The circuit shown in Figure 1 is capable of driving an LED array requiring up to several amps with a burst of flashes before coming on until power is removed. It is intended to be used as an auxiliary warning light driver. The initial burst of flashes is meant to enhance visual detection of

Introduction We designed a multi-zone fire alarm system with a VT100-compatible user interface. The system is microprocessor controlled using the Mega32 microprocessor. The system communicates to the VT100-compatible user interface via a RS232 connection. A fire is detectable by a number of fire detection devices in each of as many as eight zones. High-level Design

Content Page 1. Introduction 1.1 Sound-Bite Our final project recreates Rush Hour as a video game that is played using a touchpad implemented using 2D electric-field (E-field) sensors. 1.2 Motivation Rush Hour appealed to us as one of the better puzzles out there. Its level of difficulty can range from simple games to hard ones, thus making
