Detailed Description

A frame readout from a DAQ Link.

The header and common mode words are unpacked into memory while the DAQ and Calibration samples are given to Sample to be unpacked only upon request.

Constructor & Destructor Documentation

pflib::packing::DAQLinkFrame::DAQLinkFrame ( std::span< uint32_t > data )

Construct from a std::span over 32-bit words.

Note: A std::span can be transparently constructed from a std::vector if that is what is available, but it can also be used to simply view a subslice of a larger std::vector.

std::array<bool, 7> pflib::packing::DAQLinkFrame::corruption

Corruption checks on the data.

Index	Description
0	header leading four bits are wrong
1	CRC does not match
2	error present in one of the counters
3	error present in first quarter (ch0-17 and cm)
4	error present in second quarter (calib and ch18-35)
5	header trailing four bits are wrong
6	common mode leading 12 bits are wrong
