Dog finder - Track Logger
[InfoShortDescription.cs]
Psí vyhledávač - záznamník trasy
[InfoLongDescription.en]
The track is logged in NMEA format on SD/MMC card.
[InfoLongDescription.cs]
Umožňuje zaznamanat trasu opakovaně utíkajícího psa. A tím nalézt zdroj problémů, například díru v plotě :)
Trasa je zaznamenávána na SD/MMC kartu ve formátu NMEA.

/-----------------------------------------------------------------------------/
/ Feb 26,'06 R0.00 Prototype.
/
/ Apr 29,'06 R0.01 First stable version.
/
/ Jun 01,'06 R0.02 Added FAT12 support.
/ Removed unbuffered mode.
/ Fixed a problem on small (<32M) patition.
/ Jun 10,'06 R0.02a Added a configuration option (_FS_MINIMUM).
/
/ Sep 22,'06 R0.03 Added f_rename().
/ Changed option _FS_MINIMUM to _FS_MINIMIZE.
/ Dec 11,'06 R0.03a Improved cluster scan algolithm to write files fast.
/ Fixed f_mkdir() creates incorrect directory on FAT32.
/
/ Feb 04,'07 R0.04 Supported multiple drive system.
/ Changed some interfaces for multiple drive system.
/ Changed f_mountdrv() to f_mount().
/ Added f_mkfs().
/ Apr 01,'07 R0.04a Supported multiple partitions on a plysical drive.
/ Added a capability of extending file size to f_lseek().
/ Added minimization level 3.
/ Fixed an endian sensitive code in f_mkfs().
/ May 05,'07 R0.04b Added a configuration option _USE_NTFLAG.
/ Added FSInfo support.
/ Fixed DBCS name can result FR_INVALID_NAME.
/ Fixed short seek (<= csize) collapses the file object.
/
/ Aug 25,'07 R0.05 Changed arguments of f_read(), f_write() and f_mkfs().
/ Fixed f_mkfs() on FAT32 creates incorrect FSInfo.
/ Fixed f_mkdir() on FAT32 creates incorrect directory.
/ Feb 03,'08 R0.05a Added f_truncate() and f_utime().
/ Fixed off by one error at FAT sub-type determination.
/ Fixed btr in f_read() can be mistruncated.
/ Fixed cached sector is not flushed when create and close
/ without write.
/
/ Apr 01,'08 R0.06 Added fputc(), fputs(), fprintf() and fgets().
/ Improved performance of f_lseek() on moving to the same
/ or following cluster.
