* @brief Low level disk I/O module skeleton for FatFs
|
||||
* @note If a working storage control module is available, it should
|
||||
* be attached to the FatFs via a glue function rather than
|
||||
* modifying it.\n
|
||||
* This is an example of glue functions to attach various
|
||||
* exsisting storage control module to the FatFs module with a
|
||||
* defined API.
