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 Probably an outdated version of hardware.

# 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.
