Port of the Arduino IDE, core, libraries and bootloader to support the Atmel XMEGA family of chips.

Currently supported boards:

• AVR xplain board
• Akafuino X board
• Sparkfun xmega100 breakout board

The following boards should work with a little tweaking:

• Magnetovore
• Megavore
• Boston Android

This project has replaced the xmegaduino project on Google Code (http://code.google.com/p/xmegaduino/) and has been active since September 2011. It supersedes the earlier xplainduino.

• Windows
• OS X
• Linux 32-bit
• Linux 64-bit

• AVR xplain board

The LUFA project provides a replacement USB firmware that can act as a PDI programmer. You can also use a PDI programmer such as the AVR Dragon.

• Sparkfun xmega100

Requires a PDI programmer, such as the AVR Dragon in order to upload sketches and burn bootloaders.

• Akafuino X

Comes with a bootloader pre-installed and can be used directly from the Xmegaduino IDE.

The Xmegaduino project is beta quality, and not all the features of the Arduino IDE are supported yet.

Working features:

• digitalRead and digitalWrite
• millis and delay
• micros and delayMicroseconds
• Serial on USB (USARTC0), Serial1 on pins D2/D3 (USARTD0) and Serial2 on D6/D7 (USARTD1).
• analogRead
• analogWrite
• attachInterrupt, detachInterrupt, interrupts, noInterrupts
• Upload using bootloader over usb port, D2/3, or D6/7.
• Burning bootloader from arduino IDE
• DAC (using xmDAC library)
• Wire
• shiftOut, shiftIn, pulseIn (not tested)
• tone
• SPI library
• EEPROM library

Todo:

• analogReference
• Ethernet library
• Servo library
• Stepper library

Beta5 (based on Arduino 1.5.2-rc2):

• New avr-gcc 4.8.1, avrdude 6.1
• Many many updates

Beta4 (based on Arduino 1.0.1-rc2):

• New avr-gcc 4.5.1, avr-libc 1.7.1 for all platforms (Windows, Mac OS X, Linux 32/64)
• Linux now comes with bundled avr-gcc and avr-libc
• Use correct SPI port on Akafuino X (pin 10-13)
• Upload sketch to XPlain using PDI
• Translated to 23 different languages (Thanks to Arduino)

Beta3 (based on Arduino 1.0):

Big thanks goes out to Brendan Powers and Russell for their contributions

• xmDAC now works again
• EEPROM library fixed
• All baud rates are now dynamically calculated
• SPI library ported
• shiftIn function implemented
• tone implemented using timer TCC1
• LEVEL interrupt mode
• Replicated Arduino's pullup behavior when writing to an input pin
