  50  *  \section Sec_Description Project Description:
  51  *
  52  *  Temperature Data Logger project. This project is a very basic USB data logger for the current temperature as reported by
  53  *  the board's temperature sensor, writing the temperature to a file stored on the board's Dataflash in a FAT filesystem
  54  *  each time a specified interval elapses. When inserted into a PC, the datalogger will appear as a standard USB Mass Storage
  55  *  device with a single text file, which contains the logged data. Files are named according to the current date when the
  56  *  logging commences.
  57  *
  58  *  A DS1307 or compatible RTC IC is designed to be attached to the AVR's TWI bus, for the management of timestamps on the
  59  *  sampled data. This project will not function correctly if the RTC chip is omitted unless the DUMMY_RTC compile time token
  60  *  is specified - see \ref Sec_Options.
  61  *
  62  *  Due to the host's need for exclusive access to the file system, the device will not log samples while connected to a host.
  63  *  For the logger to store data, the Dataflash must first be formatted by the host so that it contains a valid FAT file system.
  64  *
  65  *  This project uses the FatFS library from ELM Chan (http://elm-chan.org/fsw/ff/00index_e.html) and the .NET HID device library
  66  *  LibHIDNet (http://sourceforge.net/projects/libhidnet/).
