This project is a very basic USB data logger for the current temperature as reported by * the board's temperature sensor, writing the temperature to a file stored on the board's Dataflash in a FAT filesystem * each time a specified interval elapses. When inserted into a PC, the datalogger will appear as a standard USB Mass Storage * device with a single text file, which contains the logged data. Files are named according to the current date when the * logging commences. * * A DS1307 or compatible RTC IC is designed to be attached to the AVR's TWI bus, for the management of timestamps on the * sampled data. This project will not function correctly if the RTC chip is omitted unless the DUMMY_RTC compile time token * is specified - see \ref Sec_Options. * * Due to the host's need for exclusive access to the file system, 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 file system. * * This project uses the FatFS library from ELM Chan (http://elm-chan.org/fsw/ff/00index_e.html) and the .NET HID device library * LibHIDNet (http://sourceforge.net/projects/libhidnet/). * * \section Sec_Options Project Options * * The following defines can be found in this demo, which can control the demo behaviour when defined, or changed in value. * * <table> * <tr> * <td><b>Define Name:</b></td> * <td><b>Location:</b></td> * <td><b>Description:</b></td> * </tr> * <tr> * <td>DUMMY_RTC</td> * <td>Makefile LUFA_OPTS</td> * <td>When a DS1307 RTC chip is not fitted, this token can be defined to make the demo assume a 1/1/1 01:01:01 date/time * stamp at all times, effectively transforming the project into a basic data logger with no specified sample times.</td> * </tr> * </table> */
