  *  Temperature Data Logger project. This project is a very basic USB data logger for the current temperature as reported by

- *  Currently there is no timestamp associated with the logged data; this project can be extended by the addition of a Real

+ *  A DS1307 or compatible RTC IC is designed to be attached to the AVR's TWI bus, for the management of timestamps on the

+ *  is specified - see \ref SSec_Options.

  *

  *  Due to the host's need for exclusive access to the filesystem, the device will not log samples while connected to a host.

  *  For the logger to store data, the Dataflash must first be formatted by the host so that it contains a valid FAT filesystem.
