Flashing Instructions

There's no need for an extra flashing device, it has a bootloader so it can be programmed directly via usb. The only thing needed is the "dfu-programmer" software, more info: https://dfu-programmer.github.io/.

lsusb

Find the Atmega device in the list. If it's already been flashed, it will show up as "dc24:1337". To get it into a mode to reflash it, follow the directions in the "Reflashing" section.

sudo chown 666 /dev/bus/usb/02/020
dfu-programmer atmega32u2 erase --force
dfu-programmer atmega32u2 flash --suppress-bootloader-mem blinkybadge-test.hex

Reflashing

Run the "reset_badge.py" script to temporarily enable flashing.

python reset_badge.py
