Fresh hacks every day
[Fli] assembled an AVR based system that can assign IPv6 addresses to 1-wire components. An AVR ATmega644 microcontroller is used in conjunction with an ENC28J60 ethernet controller chip. To get up and running with IPv6 on this meek hardware [Fli] ported the uIPv6 stack from the contiki project over to the AVR framework. Although he encountered some hardware snafus along the way, in the end he … [Read more...]
[Peter] deserves an award for doing more with less. He's built a handheld device based on an AVR controller that has features normally associated with much more powerful devices. Here's what it doesn't do: no phone calls, no text messages, no accelerometer, and best of all no app approval needed. What it does do is leverage inexpensive, readily available components combined with common homebrew … [Read more...]
Have you always wished that you could develop games for the Super Nintendo but couldn't because you were only 4 years old when it was released in 1990? Here's a second chance. [Max] and his team have created a SNES developer's cartridge that allows you to load your own code, run it on the SNES, and debug as needed. At its core is an Atmel AVR ATmega644 that is running a boot loader, allowing for … [Read more...]
Reader, [Lennon Luks] made a really slick MIDI sequencer/controller for his senior design project while studying at Western Carolina University. It has a grid of 64 LED buttons, 8 knobs, and a display with navigation buttons that allow him to sequence tracks with or without a computer. The controller is based off an ATmega644 and is programmed in C. [Lennon] clearly explains the inner workings … [Read more...]
When the RepRap team found themselves pushing the limits of the Arduino, they started looking for alternatives. They found it in the ATMega644P. It has four times the memory and four times the RAM compared to the ATMega168 used in the standard Arduino. It also has 32 I/O pins. They ported the Arduino software to the microcontroller and started producing Sanguino boards. Now that the base design is … [Read more...]
Our friend [Zach Hoeken] at NYC Resistor is porting the Arduino environment to an ATmega644 chip. This doesn't really add new functionality to the ATmega644 as it is already fully programmable, but it does add a user-friendly and familiar environment to the ATmega, allowing users to build their Arduino-based projects with more powerful hardware. The ATmega is, after all, the biggest DIP package … [Read more...]
