Struct EmulatedUsbBus

pub struct EmulatedUsbBus { /* private fields */ }

Implements usb-device UsbBus on top of UsbBusImpl.

Not thread-safe.

Implementations

impl EmulatedUsbBus

pub fn get_address(&self) -> u8

Returns USB Address assigned to Device by the Host.

Trait Implementations

impl UsbBus for EmulatedUsbBus

fn alloc_ep( &mut self, ep_dir: UsbDirection, ep_addr: Option<EndpointAddress>, ep_type: EndpointType, max_packet_size: u16, _interval: u8, ) -> UsbDeviceResult<EndpointAddress>

Allocates an endpoint and specified endpoint parameters. This method is called by the device and class implementations to allocate endpoints, and can only be called before enable is called.

fn enable(&mut self)

Enables and initializes the USB peripheral. Soon after enabling the device will be reset, so there is no need to perform a USB reset in this method.

fn force_reset(&self) -> UsbDeviceResult<()>

Simulates a disconnect from the USB bus, causing the host to reset and re-enumerate the device.

fn poll(&self) -> PollResult

Gets information about events and incoming data. Usually called in a loop or from an interrupt handler. See the PollResult struct for more information.

fn read( &self, ep_addr: EndpointAddress, buf: &mut [u8], ) -> UsbDeviceResult<usize>

Reads a single packet of data from the specified endpoint and returns the actual length of the packet.

fn reset(&self)

Called when the host resets the device. This will be soon called after poll returns PollResult::Reset. This method should reset the state of all endpoints and peripheral flags back to a state suitable for enumeration, as well as ensure that all endpoints previously allocated with alloc_ep are initialized as specified.

fn resume(&self)

Resumes from suspend mode. This may only be called after the peripheral has been previously suspended.

fn suspend(&self)

Causes the USB peripheral to enter USB suspend mode, lowering power consumption and preparing to detect a USB wakeup event. This will be called after poll returns PollResult::Suspend. The device will continue be polled, and it shall return a value other than Suspend from poll when it no longer detects the suspend condition.

fn set_device_address(&self, addr: u8)

Sets the device USB address to addr.

fn is_stalled(&self, ep_addr: EndpointAddress) -> bool

Gets whether the STALL condition is set for an endpoint.

fn set_stalled(&self, ep_addr: EndpointAddress, stalled: bool)

Sets or clears the STALL condition for an endpoint. If the endpoint is an OUT endpoint, it should be prepared to receive data again.

fn write(&self, ep_addr: EndpointAddress, buf: &[u8]) -> UsbDeviceResult<usize>

Writes a single packet of data to the specified endpoint and returns number of bytes actually written.

const QUIRK_SET_ADDRESS_BEFORE_STATUS: bool = false

Indicates that set_device_address must be called before accepting the corresponding control transfer, not after.
