1. Get LUFA library:

   git submodule init
   git submodule update

2. Compile the software:

   make

3. Set your Moodlight to programming mode by holding the HWB button and pressing the RESET button.

4. Erase the old binary from your Moodlight (may require root privilege):

   dfu-programmer atmega32u2 erase

5. Flash the new binary onto your Moodlight (may require root privilege):

   dfu-programmer atmega32u2 flash Moodlight.hex 

6. Write initial colour sequence to eeprom:

   dfu-programmer atmega32u2 flash-eeprom Moodlight.eep

7. Reset your Moodlight by pressing the RESET button.
8. Tell your Moodlight to blink for you (see PyMood Project)

• Check if logarithm table is okay, also whether to use it for HSV or not. HSV hue fading looks better when not using logarithmic PWM.

• Introduce instruction to write eeprom from application

  Something like "write n bytes following this to address p"

• Move LUFA interfacing code further away from genericHID echo demo

This description is focused on the lowlevel programming of colour sequences.

The Moodlight uses a simple bytecode format to execute sequences of colour changes. The instructions are inspired by the BlinkM project.

Initially, execution starts at the beginning of the built-in EEPROM, but every HID report sent from connected host devices is immediatly executed and may run until the next report arrives or jump back into EEPROM.
