Detailed Description

Utility class for resolving endpoints.

This class is intended to make the process of selecting the correct endpoint from a device endpoint table easier. It also provides a verification function to check if the device has enough resources for the given configuration.

endpoint_ctrl()

void endpoint_ctrl

(

uint32_t

size

)

Add control endpoint size.

Parameters

size	Space reserved for control in and control out

endpoint_in()

usb_ep_t endpoint_in	(	usb_ep_type_t	type,
		uint32_t	size
	)

Return a free IN endpoint of the given size.

Parameters

type	Desired endpoint type
size	Space to reserve for this endpoint

Returns

Endpoint index or 0 if there are not enough resources

endpoint_out()

usb_ep_t endpoint_out	(	usb_ep_type_t	type,
		uint32_t	size
	)

Return a free OUT endpoint of the given size.

Parameters

type	Desired endpoint type
size	Space to reserve for this endpoint

Returns

Endpoint index or 0 if there are not enough resources

next_free_endpoint()

usb_ep_t next_free_endpoint	(	bool	in_not_out,
		usb_ep_type_t	type,
		uint32_t	size
	)

Get next free endpoint.

valid()

bool valid

(

)

Check if the endpoint configuration created so far is valid.

Returns

true if all endpoint sizes are available and fit, false otherwise

reset()

void reset

(

)

Reset this class's state to when it was constructed.
