Detailed Description

Class for accessing raw WIB eth frames, as used in ProtoDUNE-II.

The canonical definition of the WIB format is given in EDMS document 2088713: https://edms.cern.ch/document/2088726/XXX, (XXX a stand-in for the doc version, e.g. 5)

Member Function Documentation

get_adc()

uint16_t dunedaq::fddetdataformats::DAPHNEEthFrame::get_adc ( int i ) const

inline

Get the ith ADC value in the frame.

The ADC words are 14 bits long, stored packed in the data structure. The order is:

• 1024 adc values from one daphne channel

Definition at line 5 of file DAPHNEEthFrame.hxx.

{
 
  // We're static_casting the returned DAPHNEEthFrame::word_t to a uint16_t, which is fine since
  // the ADC value is guaranteed to be storable in 16 bits
 
  return static_cast<uint16_t>(dunedaq::fddetdataformats::get_adc_1d<DAPHNEEthFrame::word_t,
                                                                     DAPHNEEthFrame::s_num_adc_words,

}

get_channel()

uint8_t dunedaq::fddetdataformats::DAPHNEEthFrame::get_channel ( ) const

inline

Get the channel identifier of the frame.

Definition at line 96 of file DAPHNEEthFrame.hpp.

{ return header.channel; }

get_timestamp()

uint64_t dunedaq::fddetdataformats::DAPHNEEthFrame::get_timestamp ( ) const

inline

Get the starting 64-bit timestamp of the frame.

Definition at line 90 of file DAPHNEEthFrame.hpp.

{ return daq_header.get_timestamp(); }

set_adc()

void dunedaq::fddetdataformats::DAPHNEEthFrame::set_adc ( int i, uint16_t val )

inline

Set the ith ADC value in the frame to val.

Definition at line 17 of file DAPHNEEthFrame.hxx.

{ // NOLINT
 
  dunedaq::fddetdataformats::set_adc_1d<DAPHNEEthFrame::word_t,

}

set_channel()

void dunedaq::fddetdataformats::DAPHNEEthFrame::set_channel ( const uint8_t new_channel )

inline

Set the channel identifier of the frame.

Definition at line 99 of file DAPHNEEthFrame.hpp.

{ header.channel = new_channel; }

set_timestamp()

void dunedaq::fddetdataformats::DAPHNEEthFrame::set_timestamp ( const uint64_t new_timestamp )

inline

Set the starting 64-bit timestamp of the frame.

Definition at line 93 of file DAPHNEEthFrame.hpp.

{ daq_header.timestamp = new_timestamp; }
