DAQ scripts for MMTP

Receiving UDP Packets from the TP

• To run udp receiving:

  <cmdline> python udpRecDesp_32bit.py

• This is equipped to write files for data coming from TP output FIFOs 20-23.

  1. FIFO 21: GBT data stream from ADDC to TP
  2. FIFO 20: HIT data packets after TP converts GBT data to strip data + some slopes - header A1
  3. FIFO 23: TIME data from received external scintillator trigger
  4. FIFO 22: FIT data packets after TP reorders hit to VVUU-XXXX, finds coincidences in slope roads, and fits - header A3

(FIFO 23: FIND data after TP reorders hits to VVUU-XXXX and finds coincidences - header A2) - deprecated in TP FW as of 2017-05-10

• This writes raw files in the form of mmtp_test_FIFO#.dat

Writing commands to the TP registers

<cmdline> python regWrite.py -a <address> -m <message> [-r] [-u] [--fe] <0 or 1> [--jtag] [--df] <"xxxx">

• Various options for regWrite include:
  • [-r] Reset GBT transceiver connection
  • [-u] Turn on GBT input to FIFOs
  • [--fe] Enable/Disable TP output FIFOs, requires arg 0 or 1
  • [--jtag] Use jtag commands instead (has not been tested, requires vivado), calls tcl scripts
  • [--df] Enables select TP output FIFOs, specified by four bits, e.g. "1111"

TP Output Decoding

• Use decodeGBT_32bit.py (for raw GBT packets)

  <cmdline> python decodeGBT_32bit.py [-h] [--ifile IFILE] [--ofile OFILE]

• Use decodeHIT_32bit.py (for HIT packets)

  <cmdline> python decodeHIT_32bit.py -i <inputfile> -o <outputfile> -r <run> [-f]

• Use decodeFIND_32bit.py (for FIND packets)

  <cmdline> python decodeFIND_32bit.py -i <inputfile> -o <outputfile> -r <run> [-f]

• Use decodeTIME_32bit.py (for TIME packets)

  <cmdline> python decodeTIME_32bit.py [-h] [--ifile IFILE] [--ofile OFILE]

• Use decodeFIT_uvr.py (for FIT packets with new uvr road data format)

  <cmdline> python decodeFIT_uvr.py -i <inputfile> -o <outputfile> -r <run> [-f] [--st] [--sl]

• Various flags include:

  • [-i] Input file
  • [-o] Output file
  • [-f] Offsets (decode using assumed offsets in the TP firmware)
  • [--st] Include strip information in output
  • [--sl] Include slope information in output
  • [-r] Run number

• Use decodeFIT_32bit.py (for FIT packets, deprecated)

  <cmdline> python decodeFIT_32bit.py -i <inputfile> -o <outputfile> -r <run> [-f] [-s]

• Various flags include:

  • [-i] Input file
  • [-o] Output file
  • [-f] Offsets (decode using assumed offsets in the TP firmware)
  • [-s] Include extra slope information in output
  • [-r] Run number
