Set this device to the configured state.

Enable added endpoints if they are not enabled already.

Implements USBPhy.

Make the USB phy visible to the USB host.

Enable either the D+ or D- pullup so the host can detect the presence of this device.

Implements USBPhy.

Power down this USBPhy instance.

Disable interrupts and stop sending events.

Implements USBPhy.

Detach the USB phy.

Disable the D+ and D- pullup and stop responding to USB traffic.

Implements USBPhy.

Abort the current transfer if it has not yet been sent.

Parameters

endpoint

Endpoint to abort the transfer on. It is implementation defined if this function has an effect on receive endpoints.

Implements USBPhy.

Configure and enable an endpoint.

Parameters

endpoint	Endpoint to configure and enable
max_packet	The maximum packet size that can be sent or received
type	The type of endpoint this should be configured as - USB_EP_TYPE_BULK, USB_EP_TYPE_INT or USB_EP_TYPE_ISO

Note

This function cannot be used to configure endpoint 0. That must be done with ep0_set_max_packet

Implements USBPhy.

Start a read on the given endpoint.

Parameters

endpoint	Endpoint to start the read on
data	Buffer to fill with data
size	Size of the read buffer. This must be at least the max packet size for this endpoint.

Returns

true if the read was successfully started, false otherwise

Implements USBPhy.

Finish a read on the given endpoint.

Parameters

endpoint

Endpoint to check

Returns

The number of bytes received

Implements USBPhy.

Disable an endpoint.

Parameters

endpoint

Endpoint to disable

Implements USBPhy.

Perform a functional stall on the given endpoint.

Set the HALT feature for this endpoint so that all further communication is aborted.

Parameters

endpoint

Endpoint to stall

Implements USBPhy.

Get the endpoint table.

This function returns a table which describes the endpoints can be used, the functionality of those endpoints and the resource cost.

Implements USBPhy.

Un-stall the endpoint.

Clear the HALT feature on this endpoint so communication can resume.

Parameters

endpoint

Endpoint to stall

Implements USBPhy.

Start a write on the given endpoint.

Parameters

endpoint	Endpoint to write to
data	Buffer to write
size	Size of data to write

Returns

true if the data was prepared for transmit, false otherwise

Implements USBPhy.

Start receiving a packet of up to wMaxPacketSize on endpoint 0.

Parameters

data	Buffer to fill with the data read
size	Size of buffer

Implements USBPhy.

Read the contents of a received packet.

Returns

Size of data read

Implements USBPhy.

Set wMaxPacketSize of endpoint 0.

Parameters

max_packet

The wMaxPacketSize value for endpoint 0

Returns

The actual size of endpoint 0

Implements USBPhy.

Read the contents of the SETUP packet.

Parameters

buffer	Buffer to fill with data
size	Size of buffer passed in

Implements USBPhy.

Protocol stall on endpoint 0.

Stall all IN and OUT packets on endpoint 0 until a setup packet is received.

Note

The stall is cleared automatically when a setup packet is received

Implements USBPhy.

Write a packet on endpoint 0.

Parameters

buffer	Buffer fill with data to send
size	Size of data to send

Implements USBPhy.

Initialize this USBPhy instance.

This function must be called before calling any other functions of this class, unless specifically noted.

Parameters

events

Callback class to handle USB events

Implements USBPhy.

Check if USB power is present.

Devices which don't support checking the USB power state must always return true.

Returns

true if USB power is present, false otherwise

Implements USBPhy.

Callback used for performing USB processing.

USBPhy processing should be triggered by calling USBPhyEvents::start_process and done inside process. All USBPhyEvents callbacks aside from USBPhyEvents::start_process must be called in the context of process

Implements USBPhy.

Wake upstream devices.

Implements USBPhy.

Set the USBPhy's address.

Parameters

address

This device's USB address

Implements USBPhy.

Disable the start of frame interrupt.

Stop calling USBPhyEvents::sof.

Implements USBPhy.

Enable the start of frame interrupt.

Call USBPhyEvents::sof on every frame.

Implements USBPhy.

Leave the configured state.

This is a notification to the USBPhy indicating that the device is leaving the configured state. The USBPhy can disable all endpoints other than endpoint 0.
