hi Everybody,
i am working on usb host mass storage class with fat file system ( lpc 1768 + ChaN library ).
in this library there is a diskio.c containing physical layer interface which establishs a connection between hardware ( usb host ) and application ( fat functions ).
how the physical layer is established between usb host circuit and fat file firmware?
and what should happen there?
i have several questions:
how fat functions read from usb or write to it?
how the fat does communicate to usb?
...
regards, Rasool
hi Andrew,
thank you for the replies to this post and http://www.keil.com/forum/62153/.
i find the theory and fundamentals for doing that ( usb interface to fat ).
