							|  |  |  |  * | 
					
						
							|  |  |  |  *  Dual LUN Mass Storage demonstration application. This gives a simple | 
					
						
							|  |  |  |  *  reference application for implementing a multiple LUN USB Mass Storage | 
					
						
							|  |  |  |  *  device using the basic USB UFI drivers in all modern OSes (i.e. no | 
					
						
							|  |  |  |  *  special drivers required). | 
					
						
							|  |  |  |  *   | 
					
						
							|  |  |  |  *  On start-up the system will automatically enumerate and function as an | 
					
						
							|  |  |  |  *  external mass storage device with two LUNs (separate disks) which may | 
					
						
							|  |  |  |  *  be formatted and used in the same manner as commercial USB Mass Storage | 
					
						
							|  |  |  |  *  devices. | 
					
						
							|  |  |  |  *  	 | 
					
						
							|  |  |  |  *  You will need to format the mass storage drives upon first run of this | 
					
						
							|  |  |  |  *  demonstration - as the device acts only as a data block transport between | 
					
						
							|  |  |  |  *  the host and the storage media, it does not matter what file system is used, | 
					
						
							|  |  |  |  *  as the data interpretation is performed by the host and not the USB device. | 
					
						
							|  |  |  |  *   | 
					
						
							|  |  |  |  *  This demo is not restricted to only two LUNs; by changing the TOTAL_LUNS | 
					
						
							|  |  |  |  *  value in MassStorageDualLUN.h, any number of LUNs can be used (from 1 to | 
					
						
							|  |  |  |  *  255), with each LUN being allocated an equal portion of the available | 
					
						
							|  |  |  |  *  Dataflash memory. | 
					
						
							|  |  |  |  * | 
					
						
							|  |  |  |  *  The USB control endpoint is managed entirely by the library using endpoint | 
					
						
							|  |  |  |  *  interrupts, as the INTERRUPT_CONTROL_ENDPOINT option is enabled. This allows for | 
					
						
							|  |  |  |  *  the host to reset the Mass Storage device state during long transfers without | 
					
						
							|  |  |  |  *  the need for complicated polling logic. |
