Developers of the BoardX started a kickstarter project with a target of $5K. They have reached their goal and overshoot it. Congratulations. The BoardX is a multiprocessor development board we wrote about in an earlier post. It accepts custom modules with a large choice of processors and peripherals. Via the comments.

First steps in designing projects with AVR microcontrollers
Pete made a nice tutorial on the fist steps of designing projects with AVR microcontrollers. He covers choosing the right uC for your project, finding datasheets, getting a programmer/debugger, and setting up the AVRStudio 5.1 for developing and debugging. In the wee hours of the night, I’ve been continuing to learn how to develop for […]
AVR-based PIC programmer update
Fezoj made some updates to the user interface of his AVR-based PIC programmer. The project supports the PIC24F microcontrollers used in the Bus Pirate. There’s still lots of work to be done on this project, so if you’d like to contribute join the discussion in the forum.
Little Wire – Minimal AVR programmer update
Ihsan made some updates to his Little Wire project. In order to reach more people out there , i wrote a Processing library for the Little-Wire. It’s still in progress but i’m uploading an example Analog voltage plotting program screenshot that i tested. I used mainly two sources to achive this library. Here is one. […]
AVR transistor tester build
Alan Garfield at fromorbit writes: Hey guys, I built up that AVR Transistor Tester that’s been bouncing around on your site for a few weeks. Thought you might like to see it. I’ve done this short video showing it in operation and also written up a few of the misadventures I had while building it. […]
App note: Enhancing ADC resolution by oversampling
Better ADC resolution can be accomplished by oversampling two or more ADC readings and then averaging them. If you’re not satisfied with a microcontroller’s 10 bit ADC and need more resolution, check out this application note from Atmel. Increasing the ADC resolution by one bit requires 4 ADC measurements. Four 10 bit readings are needed […]
Little Wire UART bootloader
Kehribar added a UART bootloader to his Little Wire AVR multi-tool. The Little Wire is an AVR programmer that can also be used as an SPI bridge, analog-to-digital converter, and PWM generator. This project uses the ATtiny Reset pin, which means a high voltage programmer has to be used to setup the pin configuration fuses […]
Ultra-small vusbtiny AVR programmer
Philip wanted to make the smallest vusbtiny AVR programmer possible. His design incorporates both an edge PCB and a mini-B cable connector for the USB. Vusbtiny is a AVR programer based on the V-USB virtual low-speed USB firmware. V-USB is a software USB engine for AVR devices that don’t have hardware USB serial interface engines. […]
Transistor tester breadboard build
Arhi had some free time so he decided to test out the transistor tester. He built it on a breadboard, and quickly got it running. I was waiting for some app to compile for past few hours so I breadboarded this baby. Works like a charm :D … I had some issues programming atmega8 with […]
AVR-based transitor tester
After our recent post about the commercial semi-conductor tester we started a discussion about building a similar open source project. What came up is this AVR based transistor tester (machine translation) by Markus. It’s built around an ATmega8 IC that interfaces with a standard HD44780 16×2 character LCD. The circuit that does the testing is […]
SSD1308 OLED interface AVR library for Arduino/Teensy
Our forum regular Marcus posted a SSD1308 OLED interface library and pin connections to get you started with your Arduino/Teensy OLED projects. The display is a 0.96” 128 x 64 dot matrix that can be interfaced though both I2C or SPI interfaces, the library Marcus provides is SPI only and should allow you to get […]
Small AVR matrix toy
Greeeg posted his small AVR matrix toy in the project log forum.
Atmel AVR Dragon vs the Kraken
Null Space Labs was tired of fighting the Dragon Atmel AVR debugger, so they make made their own programmer called the Kraken: The dragon is a terrible piece of hardware when it doesn’t work right, which is often. It has a design flaw that causes a couple of chips to blow up regularly, so regularly […]
SimulAVR
SimulAVR is an open source simulator for AVR 8-bit Attiny and ATmega microcontrollers. SimulAVR can be used either standalone or as a remote target for avr-gdb. When used in gdbserver mode, the simulator is used as a back-end so that avr-gdb can be used as a source level debugger for AVR programs. The core of […]
Add auto turn-off to a cheap multimeter
Florin was tired of wasting batteries every time he forgot to turn off his multimeter. He hacked together an auto-shutdown: I bought this multimeter(Minipa ET-870C) a while ago for $17, great value. I got it because its nice to have around multiple meters for when you wanna measure both input and output voltage/current. I believe […]
RS-422 networked infrared transmitters
Gridstop posted pictures of his networked infrared transmitters in the project log forum.
QTouch library for Atmel MCUs
The Atmel QTouch Library is a royalty-free software library (GCC and IAR™) for developing touch applications on standard Atmel AT91SAM and AVR microcontrollers. Developers can use it to integrate touch-sensing capability into their applications by linking the library into firmware. The library can be used to develop single-chip solutions for many control applications or to […]
Atmel releases AVR Studio 5 beta
Atmel has released the beta version of their Atmel® AVR Studio® 5, the Integrated Development Environment (IDE) for developing and debugging embedded Atmel AVR® applications. Version 5 provides one development environment for all 8-bit and 32-bit AVR microcontrollers. Features include an integrated C compiler, new project wizard, and an improved editor displaying code suggestions, shortcuts […]
AVR decapping
Here are some examples by manekinen of what can happen when an apparently high reverse voltage is applied to several AVRs. Via Hack a Day.
RGB LED flower
This LED flower is controlled by AVR with software USB stack. It contains 6 RGB LEDs which are at the end of twisted enamelled copper wires. Project is well documented with extensive tutorial. Via mcu.cz
