In this article you will learn how to programm an ATtiny mcu using Arduino IDE.

Follows are directions for programming the ATtiny microcontrollers using the Arduino IDE. In plain English, this is how to program 8-pin Atmel chips as you would normally an Arduino. This is cool because the ATtiny is tiny, and – well – this allows you to make tiny things that don’t need a big ol’ microcontroller.

@wiki.efihacks.com :

We wrote this whole page to try to make buyers of USBasp programmer clones aware of what’s possibly out there for sale and the conclusion we came to about the units we bought, after quite some investigative work IT SIMPLY DOES NOT REALLY WORK !!!

We tried to read the flash content, and the blue led flashes, but that’s about it … it does not work :(

BO.Duino is an Arduino compatible board based on ATmega328 ATMEL’s mcu. This board features many peripherals usually externally connected on a breadboard or prototyping board such as sensors, SD card etc. Peripherals included are:

– A real-time clock
– AT24 series external memory chip
– MicroSD card adaptor (SPI)
– RGB LED
– A potentiometer on analog input
– Connector for DS18b20 or DHt11 series sensors

Atmel’s Core-A5-based MPU handles displays up to 2048 × 2048

Atmel’s Core-A5-based MPU handles displays up to 2048 × 2048

By Jim Harrison:

The human-machine interface, once simply known as an “operator panel” or “terminal”, is changing rapidly, due to the graphical, visual way operators now interact with an industrial machine or process. At one time, designers of these systems could get by with a three-line segmented LCD display. Today, LCD interfaces are quickly replacing traditional LED and segment LCD displays as designers take advantage of the aesthetic, flexibility, and cost benefits they provide.

Analog-to-digital-conversion (ADC) is required in Embedded Systems to deal with various analog world parameters such as current, pressure, motion, temperature, etc. An ADC is an electronic system or a module that has analog input, reference voltage input and digital outputs. The ADC convert the analog input signal to a digital output value that represents the size of the analog input comparing to the reference voltage. It basically samples the input analog voltage and produces an output digital code for each sample taken. This application note from Atmel describes the fundamental concepts of ADC and the associated parameters that determine the performance and accuracy of the ADC’s output.

adafruit.com launched a new little micro controller board board based on ATtiny85.

Trinket may be small, but do not be fooled by its size! It’s a tiny microcontroller board, built around the Atmel ATtiny85, a little chip with a lot of power. We wanted to design a microcontroller board that was small enough to fit into any project, and low cost enough to use without hesitation. Perfect for when you don’t want to give up your expensive dev-board and you aren’t willing to take apart the project you worked so hard to design. It’s our lowest-cost arduino-IDE programmable board!

What’s with mint boxes and electronics? Beats me, but they are somehow made for each other. I had built ladyada’s USBtinyISP v1.0 circuit on a breadboard which I used every other day. It worked sporadically(and never at hour of need), used up half of my breadboard and looked ugly. So I decided to try my hand at home PCB fabrication and build it in, of course, a tiny tic-tac box. Since I was a beginner, the circuit is easy and single-sided and uses crystal instead of ceramic oscillator.

IR Communications for Atmel Mega644/1284 microcontrollers.

Infrared (IR) can be used for line-of-sight communications over low to moderate range. IR is nice because of the lack of interference (except for sun and compact fluroscent lights) and freedom from FCC regulation. The web site http://tthheessiiss.wordpress.com/2009/08/05/dirt-cheap-wireless/ (Jacob Sikker Remin, 2009) shows how to use a IR remote control receiver and IR LED to send ASCII serial data in a simple, but unreliable, fashion with no error control, packetizing, or other overhead. The transmitter drive uses a clever method to modulate and invert the serial output from the USART transmitter. The circuit is shown below.

Alberto Maccioni posted an update on his multi-chip opensource programmer based on a PIC18F2550. It supports PIC, I2C-SPI-MicroWire EEPROMs, some ATMEL AVRs, and (soon) other devices:

In the last few years, as serial and parallel interfaces have almost disappeared, electronics enthusiasts find even more difficult to program microcontrollers; old time programmers don’t work any more; common solutions include using USB to serial adapters (which can’t accept direct access but only slow API calls), or add-on interface chips, like FTDIxxxx, which appear substantially as serial interfaces and require custom or proprietary drivers. So why not use PIC controllers and their native USB interface? After searching a while I couldn’t find an USB programmer which was at the same time functional, free, and open source, so I decided to design one.

Leonardo just started a new blog where he will talk about electronics including Atmel MCU (ATMega, XMega,..) and ASF (Atmel Software framework) with articles and examples. Blog is in Italian :) but also a computer-translated version is available. Check it out…
