Detailed Description

DHC frame wrapper class.

Contains functions common for all type of frames (CRC etc) Provides a union pointer to the different struct types See Data format definitions [BELLE2-NOTE-TE-2016-009] on https://docs.belle2.org/

◆ check_padding()

PXDError::PXDErrorFlags check_padding ( )

TODO many false positives, we should remove that check after we KNOW that it has been fixed in DHH Firmware
