Functions

RadctrlPacket parse_radctrl_packet(std::string message)¶

Parses a string into a RadctrlPacket, if possible.

Parameters:: message – [in] The message in string form
Returns:: A struct containing the parsed message.

std::string format_rxpacket(RxPacket packet)¶

Formats an RxPacket into a string for IPC messaging.

Parameters:: packet – [in] The RxPacket to format
Returns:: A string containing the formatted message.

std::vector<std::vector<std::complex<float>>> make_tx_samples( int total_tx_channels, const RadctrlPacket &driver_packet, std::vector<std::complex<float>*> pulse_ptrs )¶

Makes a set of vectors of the samples for each TX channel from shared memory.

Parameters:

total_tx_channels – [in] Number of tx channels.
driver_packet – [in] A received driver packet from radar_control.
pulse_ptrs – [in] Pointer for each channel in the pulse buffer.

Returns:

A set of vectors of TX samples for each USRP channel.

void transmit( zmq::context_t &driver_c, USRP &usrp_d, const DriverOptions &driver_options )¶

void receive( zmq::context_t &driver_c, USRP &usrp_d, const DriverOptions &driver_options )¶

Runs in a seperate thread to control receiving from the USRPs.

Parameters:

driver_c – [in] The driver ZMQ context.
usrp_d – [in] The multi-USRP SuperDARN wrapper object.
driver_options – [in] The driver options parsed from config.

int32_t UHD_SAFE_MAIN(int32_t argc, char *argv[])¶

UHD wrapped main function to start threads.

Creates a new multi-USRP object using parameters from config file. Starts receive and transmit threads to operate on the multi-USRP object.

Returns:: EXIT_SUCCESS
