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
