# On command line:
|

#
|

# make all = Make software
|

#
|

# make clean = Clean out built project files
|

#
|

# make program = Download the hex file to the device, using avrdude
|

# Please customize the avrdude settings below first!
|

#
|

# make filename.s = Just compile filename.c into the assembler code only
|

#
|

# make filename.i = Create a preprocessed source file for use in submitting
|

# bug reports to the GCC project.

General Description:
|
||||
This file is an example configuration (with inline documentation) for the USB
|
||||
driver. It configures V-USB for USB D+ connected to Port D bit 2 (which is
|
||||
also hardware interrupt 0 on many devices) and USB D- to Port D bit 4. You may
|
||||
wire the lines to any other port, as long as D+ is also wired to INT0 (or any
|
||||
other hardware interrupt, as long as it is the highest level interrupt, see
|
||||
section at the end of this file).
|
||||
+ To create your own usbconfig.h file, copy this file to your project's
|
||||
+ firmware source directory) and rename it to "usbconfig.h".
|
||||
+ Then edit it accordingly.
