Detailed Description

The device interface represents the hardware. The API allows for discovery, configuration, and streaming.

Member Function Documentation

◆ find()

static device_addrs_t uhd::device::find ( const device_addr_t hint,
device_filter_t  filter = ANY 
)
static

Find devices attached to the host.

The hint device address should be used to narrow down the search to particular transport types and/or transport arguments.

Parameters
hinta partially (or fully) filled in device address
filteran optional filter to exclude USRP or clock devices
Returns
a vector of device addresses for all devices on the system

◆ get_device_type()

device_filter_t uhd::device::get_device_type ( ) const

Get device type.

◆ get_rx_stream()

virtual rx_streamer::sptr uhd::device::get_rx_stream ( const stream_args_t args)
pure virtual

Make a new receive streamer from the streamer arguments.

Note: There can always only be one streamer. When calling get_rx_stream() a second time, the first streamer must be destroyed beforehand.

◆ get_tree()

uhd::property_tree::sptr uhd::device::get_tree ( void  ) const

Get access to the underlying property structure.

◆ get_tx_stream()

virtual tx_streamer::sptr uhd::device::get_tx_stream ( const stream_args_t args)
pure virtual

Make a new transmit streamer from the streamer arguments.

Note: There can always only be one streamer. When calling get_tx_stream() a second time, the first streamer must be destroyed beforehand.

◆ make()

static sptr uhd::device::make ( const device_addr_t hint,
device_filter_t  filter = ANY,
size_t  which = 0 
)
static

Create a new device from the device address hint.

The method will go through the registered device types and pick one of the discovered devices.

By default, the first result will be used to create a new device. Use the which parameter as an index into the list of results.

Parameters
hinta partially (or fully) filled in device address
filteran optional filter to exclude USRP or clock devices
whichwhich address to use when multiple are found
Returns
a shared pointer to a new device instance

◆ recv_async_msg()

virtual bool uhd::device::recv_async_msg ( async_metadata_t async_metadata,
double  timeout = 0.1 
)
pure virtual

DEPRECATED: Receive asynchronous message from the device

Prefer calling recv_async_msg on the associated TX streamer. This method has the problem that it doesn't necessarily know which Tx streamer is being addressed, and thus might not be delivering the expected outcome.

Parameters
async_metadatathe metadata to be filled in
timeoutthe timeout in seconds to wait for a message
Returns
true when the async_metadata is valid, false for timeout

◆ register_device()

static void uhd::device::register_device ( const find_t find,
const make_t make,
const device_filter_t  filter 
)
static

Register a device into the discovery and factory system.

Parameters
finda function that discovers devices
makea factory function that makes a device
filterinclude only USRP devices, clock devices, or both
