mjr 52:63f0a9b45f0c 31 * USBMSD class: generic class in order to use all kinds of blocks storage chip
mjr 52:63f0a9b45f0c 32 *
mjr 52:63f0a9b45f0c 33 * Introduction
mjr 52:63f0a9b45f0c 34 *
mjr 52:63f0a9b45f0c 35 * The USBMSD implements the MSD protocol. It permits to access a memory chip (flash, sdcard,...)
mjr 52:63f0a9b45f0c 36 * from a computer over USB. But this class doesn't work standalone, you need to subclass this class
mjr 52:63f0a9b45f0c 37 * and define virtual functions which are called in USBMSD.
mjr 52:63f0a9b45f0c 38 *
mjr 52:63f0a9b45f0c 39 * How to use this class with your chip ?
mjr 52:63f0a9b45f0c 40 *
mjr 52:63f0a9b45f0c 41 * You have to inherit and define some pure virtual functions (mandatory step):
mjr 52:63f0a9b45f0c 42 * - virtual int disk_read(char * data, int block): function to read a block
mjr 52:63f0a9b45f0c 43 * - virtual int disk_write(const char * data, int block): function to write a block
mjr 52:63f0a9b45f0c 44 * - virtual int disk_initialize(): function to initialize the memory
mjr 52:63f0a9b45f0c 45 * - virtual int disk_sectors(): return the number of blocks
mjr 52:63f0a9b45f0c 46 * - virtual int disk_size(): return the memory size
mjr 52:63f0a9b45f0c 47 * - virtual int disk_status(): return the status of the storage chip (0: OK, 1: not initialized, 2: no medium in the drive, 4: write protection)
mjr 52:63f0a9b45f0c 48 *
mjr 52:63f0a9b45f0c 49 * All functions names are compatible with the fat filesystem library. So you can imagine using your own class with
mjr 52:63f0a9b45f0c 50 * USBMSD and the fat filesystem library in the same program. Just be careful because there are two different parts which
mjr 52:63f0a9b45f0c 51 * will access the sd card. You can do a master/slave system using the disk_status method.
mjr 52:63f0a9b45f0c 52 *
mjr 52:63f0a9b45f0c 53 * Once these functions defined, you can call connect() (at the end of the constructor of your class for instance)
mjr 52:63f0a9b45f0c 54 * of USBMSD to connect your mass storage device. connect() will first call disk_status() to test the status of the disk.
mjr 52:63f0a9b45f0c 55 * If disk_status() returns 1 (disk not initialized), then disk_initialize() is called. After this step, connect() will collect information
mjr 52:63f0a9b45f0c 56 * such as the number of blocks and the memory size.
