# Creating a GreatFET object implicitly opens the USB connection to the device.
try:
    device = GreatFET() # Optionally accepts serialNo= to select between multiple GreatFETs.
except DeviceNotFoundException:
    print("No device found!")
    sys.exit()

# Once a connection is made, the board's ID is queried, and used to make the board's peripherals available.
# (This either would be a factory method that produces an appropriate class, or a run-time mixin.)
# For now, this would mean that objects are present on 'device' that allow access to each of the Azalea board's peripherals.

Getting it to work

The device is shipped with test firmware installed. To burn a proper firmware, you will need:

• Atmel USB DFU Programmer from https://sourceforge.net/projects/dfu-programmer/
• Actual firmware files, which in worst case scenario you have to build yourself
• Incorrect instructions from https://store.ryscc.com/blogs/news/upgrading-the-firmware-on-a-chameleonmini
• Correct instructions (and a .bat file) in the firmware documentation

The instructions on the blog page are incorrect because Rev G hardware uses ATxmega128A4U instead of ATxmega32A4U. Why? Probably an outdated version of hardware.
