Storage Device Interface

A generic driver interface for storage devices that store data.

Note: currently designed for file systems (e.g. SD card, USB drive). We might need to change this interface if we ever use a storage device that doesn’t store data in files (e.g. EEPROM)

/* Check if a location exists in the storage device */ bool checkExist(const char* location); /* Read bytes from a location with an optional offset */ uint8_t read(const char* location, char data[], size_t size, size_t offset = 0); /* Write bytes from a location with an optional offset */ uint8_t write(const char* location, const char data[], size_t size, size_t offset = 0); /* Returns the length of the data at a location */ size_t length(const char* location); /* Clean up the storage device after I/O operations */ uint8_t cleanup();
