Field Documentation

uint8_t sd_raw_info::revision

The card's revision, coded in packed BCD.

For example, the revision value 0x32 means "3.2".

uint8_t sd_raw_info::manufacturing_year

The year of manufacturing.

A value of zero means year 2000.

uint8_t sd_raw_info::flag_copy

Defines wether the card's content is original or copied.

A value of 0 means original, 1 means copied.

uint8_t sd_raw_info::flag_write_protect

Defines wether the card's content is write-protected.

Note:

This is an internal flag and does not represent the state of the card's mechanical write-protect switch.

uint8_t sd_raw_info::flag_write_protect_temp

Defines wether the card's content is temporarily write-protected.

Note:

This is an internal flag and does not represent the state of the card's mechanical write-protect switch.

uint8_t sd_raw_info::format

The card's data layout.

See the SD_RAW_FORMAT_* constants for details.

Note:

This value is not guaranteed to match reality.
