To build the project you can use AVR Studio 6 or the integrated Makefile.
Important: This code comes with a fixed iotn4313 header file. If you get build errors, use this one. For example copy it to /usr/avr/include/avr/iotn4313.h
You can flash the complete firmware to your hacklace (with eeprom) using the target flashall.
