GR_UHD_API boost::shared_ptr < uhd_amsg_source > | uhd_make_amsg_source (const uhd::device_addr_t &device_addr, gr_msg_queue_sptr msgq) |
Make a new USRP asynchronous message-based source block. | |
GR_UHD_API boost::shared_ptr < uhd_usrp_sink > | uhd_make_usrp_sink (const uhd::device_addr_t &device_addr, const uhd::io_type_t &io_type, size_t num_channels) |
Make a new USRP sink block.The USRP sink block reads a stream and transmits the samples. The sink block also provides API calls for transmitter settings. | |
GR_UHD_API boost::shared_ptr < uhd_usrp_source > | uhd_make_usrp_source (const uhd::device_addr_t &device_addr, const uhd::io_type_t &io_type, size_t num_channels) |
Make a new USRP source block.The USRP source block receives samples and writes to a stream. The source block also provides API calls for receiver settings. |

size_t | num_channels | ||
) |
Make a new USRP sink block.The USRP sink block reads a stream and transmits the samples. The sink block also provides API calls for transmitter settings.
TX Stream tagging:
The following tag keys will be consumed by the work function:
The sob and eob (start and end of burst) tag values are pmt booleans. When present, burst tags should be set to true (pmt::PMT_T).
The timstamp tag value is a pmt tuple of the following: (uint64 seconds, and double fractional seconds).
See the UHD manual for more detailed documentation: http://code.ettus.com/redmine/ettus/projects/uhd/wiki
device_addr | the address to identify the hardware |
io_type | the desired input data type |
num_channels | number of stream from the device |
GR_UHD_API boost::shared_ptr<uhd_usrp_source> uhd_make_usrp_source | ( | const uhd::device_addr_t & | device_addr, |
const uhd::io_type_t & | io_type, | ||
size_t | num_channels | ||
) |
Make a new USRP source block.The USRP source block receives samples and writes to a stream. The source block also provides API calls for receiver settings.
RX Stream tagging:
The following tag keys will be produced by the work function:
The timstamp tag value is a pmt tuple of the following: (uint64 seconds, and double fractional seconds). A timestamp tag is produced at start() and after overflows.
