Introduction This page attempts to describe a procedure for installing a complete GCC-based toolchain on a modern Windows system. I’ve developed these instructions on my Windows 10 machine, but they should work for versions of Windows as far back as Windows 7. On older versions, you might want to use WinAVR. WinAVR used to be the preferred way to get […]
Introduction Many people where interested in microcontroller programming after the article which I wrote in 2002. However this first step to get the development environment up and running is the hardest. If something does not work then you have absolutely no clue where the fault is. Programmer cable wrong?? Circuit faulty? Installation incorrect? Parallel port

Code explanation for MASTER Controller: Step 1: Initialization of master. Initialization of MASTER means to set the TWI clock frequency (SCL). It is done by setting bit rate in TWBR and pre scaler bits in TWSR. Fig. 2: Equation Of

Step 1: Components and Where to Start I’ve started from the Arduino official site: https://www.arduino.cc/en/Main/Standalone where I’ve taken this picture, and where there is the list of all the components that you have to buy. Just the components that are showed in this picture. ( At the link, there are also others steps after this
Step 1: The Beginning Last week I decided to make a classic Arduino clone with an ATMEGA328P-PU. I seemed to be so easy and quick but a very bad surprise for me: I odered the cheaper ATMEGA328-PU (non P!!) that is to say: non pico power. The difference: this IC needs a bit more energy
Introduction The following diagram shows the system schematic of the Smart Plant Feeder. It contains the several major blocks: ATmega 323 is the CPU of the system. 5 VDC power supplier: an adaptor first transforms 110 VAC 60 Hz into 9 VDC; then a regulator keeps VCC stable at 5 VDC. A crystal of 32KHz
Board Design For part of my final project I want to make my own USB audio recording device. So I’ll try to develop all the necessary electronics this week. I have the analog circuitry I need from inputs week. But I don’t have a board ready to go with a USB-capable microcontroller (bit-banging will not suffice,
Atmel’s AVR series of controllers is one of the most popular with student and hobbyists. Any beginner in electronics or even professionals for that matter would appreciate an excellent development board. Development boards rid the user of the tedious tasks of prototyping and debugging necessary circuitry to run an IC. So check out the 10

Introduction This document describes how to program the Microchip ATmega328P microcontroller in C using the Avr-GCC toolchain. Students can download the software and install it on their computers by visiting a few websites. Atmel used to manufacture the ATmega328P microcontroller until it was acquired by Microchip Technology in 2016. Some documents on the EE459 website
Many factors contribute to the high demand for egg incubator around the world. A person who is interested in birds would like to raise ornamental birds, but he couldn’t find or obtain a broody bird as such; nonvegetarians eat birds, but they are often forced to eat birds raised through artificial injections; and in many
