LArPix-Packet-Maker

Script taking LArPix HDF5 output files, converting them into PACMAN packets, and simulating a readout stream based on timestamps in the data.

Requirements:

• pyzmq (tested on version 18.1.1)
• larpix-control (tested on 3.4.0)
• LArPix HDF5 data files to use it on (tested on datalog_2020_10_19_10_13_39_CEST_.h5)

readout.py

• Establishes a SUB socket to take data from the emulated PACMAN card
• Writes received messages to HDF5 file
• Run in separate terminal to packet-maker.py, press ENTER once packet-maker.py is waiting for a signal to start sending data

packet-maker.py

• Takes one argument: HDF5 file with LArPix data
• Converts the HDF5 data to packets, then into PACMAN style messages
• Optionally writes those messages to file before sending
• Sends messages at a rate defined by timestamps in the data (waits as long as the difference between timestamps of each message)

hdf5-to-print-txt.py

• Takes one argument: HDF5 file with LArPix data
• Dumps to txt files strings representing: full LArPix packets, LArPix message packet tuples, byte messages, and timestamps extracted from the HDF5
