=head1 NAME

F<avr-fuses> - a commandline fuse value calculator for F<AVR> microcontrollers


   $ avr-fuses --part m328
   -U efuse:w:0xFF:m -U hfuse:w:0xD9:m -U lfuse:w:0x62:m

   $ avr-fuses --part m328 CKDIV8=1
   -U efuse:w:0xFF:m -U hfuse:w:0xD9:m -U lfuse:w:0xE2:m


This program interprets the contents of definition files ("ATDF files")
provided by Microchip (formerly Atmel) that describe the configuration fuses
of AVR microcontrollers.

Individual fuses may be named on the commandline, each giving a value in the
form C<NAME=VALUE>. These will be applied on top of the default values for the
chosen part.

The program ends by printing new values for the fuse configuration registers,
in a form suitable to paste directly into an F<avrdude> commandline. This may
be useful in a shell fragment, such as

   $ avrdude -c avrisp -p m328 $(avr-fuses -p m328 CKDIV8=1)

=head1 OPTIONS

=head2 -h, --help

Displays a summary of the commandline and options

=head2 -v, --verbose

Describe the meaning of each individual named fuse while parsing it

=head2 -p, --part NAME

Gives the part name of the chosen microcontroller. Parts may be specified
in the following ways:



Specfically, these are the same forms as recognised by F<avr-gcc>'s C<-mmcu>
option and F<avrdude>'s C<-p> option, for convenience in Makefiles and build

=head2 -f, --fuse FUSE=VALUE

Supplies a value from one of the fuse configuration registers. This is useful
combined with the C<--verbose> option to decode values read from an AVR chip.
