The AVRPi-32U4 is an Atmel ATmega32U4 add on board for the Raspberry Pi A+, B+ and 2B. It runs on 3.3V at 8 MHz.
The ATmega32U4 is programmable as a USB device. This is useful if you want a USB HID device that can be controlled by the Raspberry Pi or yourself such as a keyboard, joystick, mouse, midi, audio or virtual serial device.
All software is easy installable navigating a simple menu. Choose:
That's all it takes to get you started.
Programming and uploading
The ATmega32U4 can be programmed in the Arduino IDE, but also using the Arduino library and a Makefile, or straight C or assembly. All software that is used on the Pi and the ATmega32U4 is open source with the source code provided.
Using the LUFA library is recommended for the AVRPi-32u4, but the Arduino library works great as well. Either in the IDE or using Arduino-Makefile in your favourite text-editor.
AVRPi boards use the latest avrdude-6.1 with the built-in linuxgpio interface.
