Requires a very recent toolchain, because ATmega32U2 is relatively new.

- Building:

  make

- Uploading the firmware to a Ben (for flashing with the atusb-pgm cable):

  make HOST=<hostname> upload

  Example:

  make HOST=ben upload

  HOST defaults to "jlime".

- Flashing the boot loader:

  Prerequisite: avrdude on the Ben.

  Disconnect the atusb board from USB. Insert the atusb-pgm connector into
  the Ben. Place the atusb-pgm adapter on the exposed contact pads of the
  atusb board and push it down. Then run

  make prog

  This takes about 30 seconds. If the programming fails with an error
  message like "Yikes!  Invalid device signature.", verify that the
  atusb-pgm board is properly connected and placed, then try again.

- Uploading the application:

  Prerequisite: dfu-util installed on the PC.

  Insert atusb into the PC, then run

  make dfu

  Note: since the boot loader resets the USB bus after timing out,
  this operation can fail with a message like "No DFU capable USB device
  found". Just retry, and it will eventually get through.
