U8

conf_nb

)

This function configures the endpoints.

Parámetros:

conf_nb

configuration number choosed by USB host

Bool usb_user_get_descriptor	(	U8	type,
		U8	string
	)

This function fills the global descriptor

Parámetros:

	type	corresponding at MSB of wValue (see USB specification)
	string	corresponding at LSB of wValue (see USB specification)

Devuelve:

FALSE, if the global descriptor no filled

U8 usb_user_interface_get

(

U16

wInterface

)

This function returns the interface alternate setting.

Parámetros:

wInterface

Interface selected

Devuelve:

alternate setting configurated

void usb_user_interface_reset	(	U16	wInterface,
		U8	alternate_setting
	)

This function selects (and resets) the interface alternate setting.

Parámetros:

	wInterface	Interface selected
	alternate_setting	alternate setting selected

Bool usb_user_read_request	(	U8	type,
		U8	request
	)

This function checks the specific request and if known then processes it

Parámetros:

	type	corresponding at bmRequestType (see USB specification)
	request	corresponding at bRequest (see USB specification)
