  4. Updated documentation to reflect that the COG v2 is used
  5. Removed examples that were not applicable
  6. Replaced the S5813A temperature library with a LM75 library for the Arduino
  7. Modified the flash driver to handle the Winbond W25Q32 that is mounted


The Sketches folder contain example programs that will compile and run on the following platforms

  1. Arduino Leonardo using the Arduino IDE
  2. Arduino Uno using the Arduino IDE
  3. Arduino Mega 2560 using the Arduino IDE (untested)

Documentation for the Arduino code can be found here.
