+ * \page udi_msc_quickstart Quick start guide for USB device Mass Storage module (UDI MSC)
+ *
+ * This is the quick start guide for the \ref udi_msc_group
+ * "USB device interface MSC module (UDI MSC)" with step-by-step instructions on
+ * how to configure and use the modules in a selection of use cases.
+ *
+ * The use cases contain several code fragments. The code fragments in the
+ * steps for setup can be copied into a custom initialization function, while
+ * the steps for usage can be copied into, e.g., the main application function.
+ *
+ * \section udi_msc_basic_use_case Basic use case
+ * In this basic use case, the "USB MSC (Single Interface Device)" module is used.
+ * The "USB MSC (Composite Device)" module usage is described in \ref udi_msc_use_cases
+ * "Advanced use cases".
+ *

+ *
+ * \section udi_msc_basic_use_case_usage Usage steps
+ *
+ * \subsection udi_msc_basic_use_case_usage_code Example code
+ * Content of conf_usb.h:
+ * \code
+ #define USB_DEVICE_SERIAL_NAME "12...EF" // Disk SN for MSC
+ #define UDI_MSC_GLOBAL_VENDOR_ID \
+ 'A', 'T', 'M', 'E', 'L', ' ', ' ', ' '

+ extern void my_callback_msc_disable(void);
+ #include "udi_msc_conf.h" // At the end of conf_usb.h file
+\endcode
+ *
+ * Add to application C-file:
+ * \code
+ static bool my_flag_autorize_msc_transfert = false;
+ bool my_callback_msc_enable(void)
+ {
+ my_flag_autorize_msc_transfert = true;
+ return true;

+ {
+ my_flag_autorize_msc_transfert = false;
+ }
+
+ void task(void)
+ {
+ udi_msc_process_trans();
+ }
+\endcode
+ *
+ * \subsection udi_msc_basic_use_case_setup_flow Workflow
+ * -# Ensure that conf_usb.h is available and contains the following configuration,
+ * which is the USB device MSC configuration:
+ * - \code #define USB_DEVICE_SERIAL_NAME "12...EF" // Disk SN for MSC \endcode
+ * \note The USB serial number is mandatory when a MSC interface is used.
+ * - \code //! Vendor name and Product version of MSC interface
+ #define UDI_MSC_GLOBAL_VENDOR_ID \
+ 'A', 'T', 'M', 'E', 'L', ' ', ' ', ' '
+ #define UDI_MSC_GLOBAL_PRODUCT_VERSION \
+ '1', '.', '0', '0' \endcode
+ * \note The USB MSC interface requires a vendor ID (8 ASCII characters)
+ * and a product version (4 ASCII characters).
+ * - \code #define UDI_MSC_ENABLE_EXT() my_callback_msc_enable()
+ extern bool my_callback_msc_enable(void); \endcode
+ * \note After the device enumeration (detecting and identifying USB devices),
+ * the USB host starts the device configuration. When the USB MSC interface
+ * from the device is accepted by the host, the USB host enables this interface and the
+ * UDI_MSC_ENABLE_EXT() callback function is called and return true.
+ * Thus, when this event is received, the tasks which call
+ * udi_msc_process_trans() must be enabled.
+ * - \code #define UDI_MSC_DISABLE_EXT() my_callback_msc_disable()
+ extern void my_callback_msc_disable(void); \endcode
+ * \note When the USB device is unplugged or is reset by the USB host, the USB
+ * interface is disabled and the UDI_MSC_DISABLE_EXT() callback function
+ * is called. Thus, it is recommended to disable the task which is called udi_msc_process_trans().
+ * -# The MSC is automatically linked with memory control access component
+ * which provides the memories interfaces. However, the memory data transfers
+ * must be done outside USB interrupt routine. This is done in the MSC process
+ * ("udi_msc_process_trans()") called by main loop:
+ * - \code * void task(void) {
+ udi_msc_process_trans();
+ } \endcode
+ * -# The MSC speed depends on task periodicity. To get the best speed
+ * the notification callback "UDI_MSC_NOTIFY_TRANS_EXT" can be used to wakeup
+ * this task (Example, through a mutex):
+ * - \code #define UDI_MSC_NOTIFY_TRANS_EXT() msc_notify_trans()
+ void msc_notify_trans(void) {
+ wakeup_my_task();
+ } \endcode
+ *
+ * \section udi_msc_use_cases Advanced use cases
+ * For more advanced use of the UDI MSC module, see the following use cases:
+ * - \subpage udi_msc_use_case_composite
+ * - \subpage udc_use_case_1
+ * - \subpage udc_use_case_2

+ *
+ * A USB Composite Device is a USB Device which uses more than one USB class.
