| 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. |

| / Feb 26, 2006 R0.00 Prototype. |
| / Apr 29, 2006 R0.01 First stable version. |
| / Jun 01, 2006 R0.02 Added FAT12 support. |
| / Removed unbuffered mode. |
| / Fixed a problem on small (<32M) patition. |
| / Jun 10, 2006 R0.02a Added a configuration option (_FS_MINIMUM). |
| / Sep 22, 2006 R0.03 Added f_rename(). |
| / Changed option _FS_MINIMUM to _FS_MINIMIZE. |
| / Dec 09, 2006 R0.03a Improved cluster scan algolithm to write files fast. |
| / Feb 04, 2007 R0.04 Added FAT32 supprt. |
| / Changed some interfaces incidental to FatFs. |
| / Changed f_mountdrv() to f_mount(). |
| / Apr 01, 2007 R0.04a Added a capability of extending file size to f_lseek(). |
| / Added minimization level 3. |
| / Fixed a problem in FAT32 support. |
| / xxx xx, 2007 R0.04b Added a configuration option _USE_NTFLAG. |
| / Added FSInfo support. |
| / Fixed some problems corresponds to FAT32 support. |
| / Fixed DBCS name can result FR_INVALID_NAME. |
