A GRBL hex file for ATmega32u4
This a HEX file compiled from the source grbl-atmega32u4-support-8c here[https://github.com/rdpowers/grbl/tree/atmega32u4-support-8c] with WINAVR.
It will be used on my Arduino Leonardo for a DIY laser engraver without fully test.
2014-04-11 There is a LUFA CDC DEMO dirver problem on WINDOWS XP. It's seems that Windows Driver Installer may function as driver for LUFA.
2014-04-12 After install Windows Driver Installer,A Teensy USB serial will list on the Ports (com and lpt1) for Device manager .Then grbl-atmega32u4-support-8c works well as gcode interpreter for Arduino Leonardo on Windows XP.
