Macro Definition Documentation

#define MASS_STORAGE_IN_EPADDR   (ENDPOINT_DIR_IN | 3)

Endpoint address of the Mass Storage device-to-host data IN endpoint.

#define MASS_STORAGE_IO_EPSIZE   64

Size in bytes of the Mass Storage data endpoints.

#define MASS_STORAGE_OUT_EPADDR   (ENDPOINT_DIR_OUT | 4)

Endpoint address of the Mass Storage host-to-device data OUT endpoint.

Function Documentation

uint16_t CALLBACK_USB_GetDescriptor	(	const uint16_t	wValue,
		const uint8_t	wIndex,
		const void **const	DescriptorAddress
	)

This function is called by the library when in device mode, and must be overridden (see library "USB Descriptors" documentation) by the application code so that the address and size of a requested descriptor can be given to the USB library. When the device receives a Get Descriptor request on the control endpoint, this function is called so that the descriptor details can be passed back and the appropriate descriptor sent back to the USB host.
