frq08711@LMECWL0871.LME.ST.COM 1:2a3ae13b45ef 31 * USBMSD class: generic class in order to use all kinds of blocks storage chip
frq08711@LMECWL0871.LME.ST.COM 1:2a3ae13b45ef 32 *
frq08711@LMECWL0871.LME.ST.COM 1:2a3ae13b45ef 33 * Introduction
frq08711@LMECWL0871.LME.ST.COM 1:2a3ae13b45ef 34 *
frq08711@LMECWL0871.LME.ST.COM 1:2a3ae13b45ef 35 * The USBMSD implements the MSD protocol. It permits to access a memory chip (flash, sdcard,...)
frq08711@LMECWL0871.LME.ST.COM 1:2a3ae13b45ef 36 * from a computer over USB. But this class doesn't work standalone, you need to subclass this class
frq08711@LMECWL0871.LME.ST.COM 1:2a3ae13b45ef 37 * and define virtual functions which are called in USBMSD.
frq08711@LMECWL0871.LME.ST.COM 1:2a3ae13b45ef 38 *
frq08711@LMECWL0871.LME.ST.COM 1:2a3ae13b45ef 39 * How to use this class with your chip ?
frq08711@LMECWL0871.LME.ST.COM 1:2a3ae13b45ef 40 *
frq08711@LMECWL0871.LME.ST.COM 1:2a3ae13b45ef 41 * You have to inherit and define some pure virtual functions (mandatory step):
frq08711@LMECWL0871.LME.ST.COM 1:2a3ae13b45ef 42 * - virtual int disk_read(char * data, int block): function to read a block
frq08711@LMECWL0871.LME.ST.COM 1:2a3ae13b45ef 43 * - virtual int disk_write(const char * data, int block): function to write a block
frq08711@LMECWL0871.LME.ST.COM 1:2a3ae13b45ef 44 * - virtual int disk_initialize(): function to initialize the memory
frq08711@LMECWL0871.LME.ST.COM 1:2a3ae13b45ef 45 * - virtual int disk_sectors(): return the number of blocks
frq08711@LMECWL0871.LME.ST.COM 1:2a3ae13b45ef 46 * - virtual int disk_size(): return the memory size
frq08711@LMECWL0871.LME.ST.COM 1:2a3ae13b45ef 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)
frq08711@LMECWL0871.LME.ST.COM 1:2a3ae13b45ef 48 *
frq08711@LMECWL0871.LME.ST.COM 1:2a3ae13b45ef 49 * All functions names are compatible with the fat filesystem library. So you can imagine using your own class with
frq08711@LMECWL0871.LME.ST.COM 1:2a3ae13b45ef 50 * USBMSD and the fat filesystem library in the same program. Just be careful because there are two different parts which
frq08711@LMECWL0871.LME.ST.COM 1:2a3ae13b45ef 51 * will access the sd card. You can do a master/slave system using the disk_status method.
frq08711@LMECWL0871.LME.ST.COM 1:2a3ae13b45ef 52 *
frq08711@LMECWL0871.LME.ST.COM 1:2a3ae13b45ef 53 * Once these functions defined, you can call connect() (at the end of the constructor of your class for instance)
frq08711@LMECWL0871.LME.ST.COM 1:2a3ae13b45ef 54 * of USBMSD to connect your mass storage device. connect() will first call disk_status() to test the status of the disk.
frq08711@LMECWL0871.LME.ST.COM 1:2a3ae13b45ef 55 * If disk_status() returns 1 (disk not initialized), then disk_initialize() is called. After this step, connect() will collect information
frq08711@LMECWL0871.LME.ST.COM 1:2a3ae13b45ef 56 * such as the number of blocks and the memory size.
