* \section Sec_Description Project Description:
|
|
|
|
|
*
|
|
|
|
|
* Temperature Data Logger project. 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/).
