Completed task: changed serial driver to use 256 byte receive buffer.
Incorrect initialization of SPI pins' DDR registers.
Added a comment.
Now watchdog interrupts trigger an underflow fault instead of asserting.
Cleaned up #includes.
Renamed DEFINE_ACTION to DEFINE_UNIMPLEMENTED_ACTION.
Replaced verify_commands() hack with init_parser() called by main.
Defined DEFINE_UNIMPLEMENTED_REPORT macro now that it's almost too late.
Now does dwell with pulsing laser.
