Member Enumeration Documentation

enum otFILE::FatFormat

Enumeration values:

F_FAT FAT12.

F_FAT32 FAT32.

F_EXFAT Extensible File Allocation Table) is a file system introduced by Microsoft in 2006 and optimized for flash memory such as USB flash drives and SD cards.

enum otFILE::FileAccess

Enumeration values:

A_READ Specifies read access to the object. Data can be read from the file.

A_WRITE Specifies write access to the object. Data can be written to the file. Combine with FA_READ for read-write access.

A_OPEN_EXISTING Opens the file. The function fails if the file is not existing. (Default).

A_CREATE_NEW Creates a new file. The function fails with FR_EXIST if the file is existing.

A_CREATE_ALWAYS Creates a new file. If the file is existing, it will be truncated and overwritten.

A_OPEN_ALWAYS Opens the file if it is existing. If not, a new file will be created.

A_OPEN_APPEND Same as FA_OPEN_ALWAYS except the read/write pointer is set end of the file.

enum otFILE::FileInfo

Enumeration values:

F_RDO Read only.

F_HID Hidden.

F_SYS System.

F_DIR Directory.

F_ARC Archive.

enum otFILE::Status

Enumeration values:

S_DISK Low level disk (SD) status.

S_FAT FatFs error codes.
