Processor quick start guides
The new processor quick start guides were a big hit. Maff^ contributed a basic guide to the AVR, and Dpropicweb greatly expanded the PIC guides. We finished the MSP430 guide, and added new guides for the Coolrunner-II CPLD and Spartan 3 FPGA (in progress). Check out all the guides, and add one for your favorite […]
Robotic toy car controlled via cellphone
Electronicseverywhere demos a project using a cellphone interfaced via an MT8870 DTMF decoder with an Atmega16 to operate servos controlling a robotic car.

Processor quick start guides
Getting started with a new processor family is a minefield. Our new quick start guides for the PIC, LPC ARM, and STM32 ARM, are a collection of notes on these processor families. If you’re already familiar with one processor, these condensed guides can help you get started on a whole new platform without scouring the […]
Writing code for AVR
Hack a Day posted the final installment of their AVR programming tutorial: writing code. See also: Introduction Hardware Compiling code
Updated AVRDude for testing
The current version of AVRDude (v5.8) is incompatible with Bus Pirate firmware v5.0-v5.9. Later today we’ll release a Bus Pirate firmware that restores compatibility with v5.8. A more permanent fix is available though. Tim updated AVRDude to be compatible with all Bus Pirate firmwares, and take advantage of some new commands to increase the programming […]

Clickable OLED display with ATMEGA32
The Teeny AVR Media Thing is a 96×64 OLED display with a click screen interface. It plays video and renders 3D graphics from an AVR32 ATMEGA32 8bit microcontroller.
ATpirate adapter kit
Eric from allthingsgeek.com writes: My friend and I work with a lot of different AVR microcontrollers. We love using the bus pirate to program them but find it inconvenient to setup a breadboard and look-up the datasheet for each one. We designed a ZIF socketed kit to make the process much easier and decided to […]
Arduino implemented on FPGA
The Gadget Factory, our partner on the Open Logic Sniffer, implemented the Arduino using an FPGA. It’s based on the AVR8 soft processor Jack developed previously for the Butterfly Platform. The Butterfly Platform is a rapid prototyping board that gets you going on FPGA projects in no time, and now you can implement things in […]
Pinguino: a PIC Arduino
Pinguino is an Arduino-like board based on PIC microcontroller. The hardware is based on a PIC 18F2550, which has an integrated USB module. This is the same chip we used in the USB IR Toy. The IDE is built with Python. An integrated preprocessor translates Arduino specific instructions directly to C. It uses SDCC as […]
Program your AVR with PICkit2
PK2AVRISP is software that lets a PICkit2 program AVR microcontrollers with no hardware or firmware changes. It decodes commands sent to a virtual serial port that emulates an AVR ISP programmer, and translates them to Pickit2 commands. It’s compatible with existing AVR development apps like AVRStudio, AVRDude, and CodeVision AVR.
Protostack v1.4 28pin AVR development board
Daniel Garcia, a friend of Dangerous Prototypes, released version 1.4 of the Protostack development board for ATMEGA8 and ATMEGA128. We really like the Protostack concept: it’s a general purpose development board that incorporates user feedback. It demonstrates the minimum circuit to get a 28pin AVR chip working, and has a large prototyping area to implement […]
Bus Pirate STK500v2 AVR programmer firmware
See the latest version in the documentation wiki. Here’s an alternate firmware for the Bus Pirate that clones an STK500 programmer for AVR microcontrollers. We ported the GPL’d source from Guido Socher’s AvrUSB500 ATMEGA8-based programmer to the PIC. The firmware should work with any applications that support the STK500 v2 protocol. We used it to […]
