It permits to access a memory chip (flash, sdcard,...) - * from a computer over USB. But this class doesn't work standalone, you need to subclass this class - * and define virtual functions which are called in USBMSD. - * - * How to use this class with your chip ? - * - * You have to inherit and define some pure virtual functions (mandatory step): - * - virtual int disk_read(char * data, int block): function to read a block - * - virtual int disk_write(const char * data, int block): function to write a block - * - virtual int disk_initialize(): function to initialize the memory - * - virtual int disk_sectors(): return the number of blocks - * - virtual int disk_size(): return the memory size - * - 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) - * - * All functions names are compatible with the fat filesystem library. So you can imagine using your own class with - * USBMSD and the fat filesystem library in the same program. Just be careful because there are two different parts which - * will access the sd card. You can do a master/slave system using the disk_status method. - * - * Once these functions defined, you can call connect() (at the end of the constructor of your class for instance) - * of USBMSD to connect your mass storage device. connect() will first call disk_status() to test the status of the disk. - * If disk_status() returns 1 (disk not initialized), then disk_initialize() is called. After this step, connect() will collect information - * such as the number of blocks and the memory size. - */ -class USB_MSD; -class USB_CDC; -class USB_HID; - -class USBMSD2: public DiskInterface, public USBDevice { -public: - /** - * Constructor - * - * @param vendor_id Your vendor_id - * @param product_id Your product_id - * @param product_release Your preoduct_release - */ - USBMSD2(uint16_t vendor_id = 0x0d28, uint16_t product_id = 0x0204, uint16_t product_release = 0x0001); - - /** - * Connect the USB MSD device.

So you can imagine using your own class with - * USBMSD and the fat filesystem library in the same program. Just be careful because there are two different parts which - * will access the sd card. You can do a master/slave system using the disk_status method. - * - * Once these functions defined, you can call connect() (at the end of the constructor of your class for instance) - * of USBMSD to connect your mass storage device. connect() will first call disk_status() to test the status of the disk. - * If disk_status() returns 1 (disk not initialized), then disk_initialize() is called.
