I have done a simple infrared remote control receiver with RS232 ascii output. It can be used for developing remote controls on a PC using the serial port. In practice, the infrared bursts are converted in ascii characters and sent to the RS232 port. The downloadable ZIP file contains the schematic diagram, the printed circuit board, the components disposition and the object file to write into the ATMEL ATtiny2313 microcontroller.

How to configure an Atmel STK500 as an Arduino-based development system.
When done, You have and STK500 running Arduino with the added advantage of pushbuttons and LEDs on board plus variable power supply (useful when working with 3.3V external sensors) and variable Analog Reference (AREF). The Analog Reference Voltage can be controlled with the “Connect” dialog box. Target Supply voltage can be controlled there also. [via]

How to connect a Nokia LCD to a AVR-Controller. he Display (which is used in Nokia 6100, 7210, 6610, 7250 and 6220) has a resolution of 132×132 pixel @4096 Colors. The visible area is about 3cm x 3cm in size. It can be found cheap at *bay.

This project makes firmware upgrades easy: The target has an Infrared receiver and the data is sent via IR. The IR transmitter is based on AVR-USB.The host-side consist of host-program for Win32 PC using Libusb-Win32, device based on ATmega8 using firmware-only USB driver by Objective Development and infrared hardware unit.Host program was compiled using Lazarus Freepascal. Device firmware was compiled using WinAVR (AVR-GCC).The implementation uses custom device class, required simple inf file and libusb driver on PC. [via]

This interface offers 12 digital inputs presented to the operating system as USB joystick with 4 directional buttons and 8 general purpose buttons. It can be used to connect historic joysticks or for general purpose digital inputs.This project uses an ATmega8 microcontroller from Atmel. and used the software-only usb driver from Objective Development.

Wow! *This* is the power move in microcontroller arena! This is big news – Microchip, along with OnSemi, are attempting to buy Atmel, a news item of potential note to those makers who use microcontrollers (the popular Ardunio for example uses an Atmel AVR)… Thanks Jaime G! [via] [photo]
Microchip Technology Incorporated (NASDAQ: MCHP) and ON Semiconductor Corporation (NASDAQ: ONNN) today announced that they have sent a proposal to the Board of Directors of Atmel Corporation (NASDAQ: ATML) to acquire Atmel for $5.00 per share in cash. The proposal, which is being led by Microchip, provides a premium of 52.4% to Atmel’s closing price of $3.28 on October 1, 2008, and values Atmel at $2.3 billion.

In this article we will see a state of the art USB programmer for the AVR microcontrollers from Atmel. The programmer firmware has no device dependent data. Therefore it works for almost any AVR microcontroller on the market and possible future microcontrollers. [via]

If you are a fan of AVR and you need to disable RESET pin and use it as regular pin you will need a High-Voltage programmer of AVR microcontrollers.HVProg is a nice High-Voltage parallel programmer.It is a redesign of the original STK500 without all components of a development board. It is based on the original ATMEL schematics that are freely available on the net (i.e at avrfreaks.net). The main target was to keep all nessecary functionality to programm all available AVR controllers in every programming mode that the STK500 supports. [via]

This is versatile development board for AVR microcontrollers ATmega48/88/168. It is good for testing and debugging embedded programs. It has many built-in peripheries connected to microcontroller so you can use them without soldering. ATmega microcontrollers are produced by ATMEL and they include a lot of features: I/O, Timers, PWM generators, ADC, RS232, TWI, SPI, Analog Comparator, Oscillator, EEPROM These microcontrollers are very versatile, easy to program and easy to use. This is the reason why I like these microcontrollers and why I decided to make development board for them.

ATMEL Microcontrollers can be programmed with ISP(In-System Programming) which helps to develop your applications because you don’t need to insert/remove the microcontroller. This is an ISP module for ATMEL Microcontroller that supports ISP such AT89SXXXX, AVR families etc. It Requires no power supply because it uses power supply from target board. This circuit needs only 10 resistors, 1 IC, 1 Capacitor,1 R-Pack.PCB size 1.6 X 4.1 cm. and Plated-Through-Hole type. [via]
