HadCon2 Apfel Controls

Introduction

This projects objective is the control of the slow control parameters of an APFEL ASIC with the HadCon2 controller board, which itself could be connected to a computer (here a Raspberry Pi (1) Model B) running an EPICS IOC. The EPICS IOCs data are visualized using the Control System Studio CSS.

Thus the project comprises
  • The implementation of the APFEL specific procotol on HadCon2's AVR
  • The implementation of an APFEL specific API command on HadCon2's AVR
  • The implementation of the EPICS IOC able to access the HadCon2's APFEL API command
  • The implementation of an CSS based GUI set to operate the APFEL
  • optional: the preparation of a Raspberry Pi Image

Sources

    APFEL Controls git repository with git submodules:

    alternatively: the single repositories

    Raspberry Pi Image, 3GB,

    • https://sf.gsi.de/d/215c097937/
      • contains complete EPICS installation (user:panda (normal) and epics (sudo))
      • needs updates via git for EPICS IOC
      • includes crontab and procServ support for the EPICS IOC

          General Operation Principles and Physical Layout

          The APFEL command set allows to talk to (several instances of) the APFEL ASIC. It uses a subset of the the I/O-Ports of the ATMEL μController to facilitate the communication to the proprietary protocol (q.v.Decoder.pdf) of the asic, sending a 22bit sequence for command, value, and chipId. ( → Apfel protocol code sequences)
          • Logically
            • Output:
              • CLK
                • quasi clock, only the level changes are important

    CSS GUI

    Installation

      HadCon2 + Firmware

      Computer + EPICS IOC

      1. requires installation of EPICS Base 3.14.12.4 (or higher) and streamDevice module, optional but recommended procServ
      2. Get IOC code from github: https://git.gsi.de/HadCon2/Applications/APFEL/APFEL_Hadcon_IOC
      3. and change to protocol_v0 branch
        git checkout protocol_v0
      4. cd TOP directory
        cd APFEL_Hadcon_IOC
      5. adjust RELEASE files in sub directory configure, i.e. correct paths to EPICS base and modules * be aware, that you might have to change instead RELEASE.linux-arm.Common RELEASE.linux-x86_64.Common, which are included in RELEASE, but allows several architectures to be supported
      6. make
        make
      7. Depending on your target architecture
        cd iocBoot/iocapfel
        or
        cd iocBoot/iocapfel_linux-x86_64
      8. Start IOC:
        1. Manually start IOC:
          ../../bin/linux-arm/apfel st.cmd
          and you must not background 'bg' this process, better use procServ
        2. procServ:
          • needs procServ installed
          1. edit <TOP>/startup/procServ/start_apfel_IOC_procServ.sh and change myIOCBOOT and myARCH to your needs
          2. call procServ:
            procServ -q -n apfelControlIOC -l 4814 4813 <absolute path to TOP>/procServ/start_apfel_IOC_procServ.sh
          3. the EPICS IOC runs now inside the procServ environment:
            1. login:
              telnet localhost 4813
              (4814: read-only)
              • type CTRL+T to toggle automatic restart
              • type CTRL+X to kill child process (IOC)
              • type exit to end the EPICS session 2. leave session: type CTRL+] and
                telnet> quit
        3. crontab + procServ
          • to restart automatically 60 seconds after reboot use crontab features
          1. edit <TOP>/startup/crontab/start_procServ_EPICS_apfel.sh and adjust myProcServScript to your needs
          2. to simplify: create a directory and softlink at your home directory, e.g.
            mkdir -p ~/crontab/ && ln -s <TOP>/startup/crontab/start_procServ_EPICS_apfel.sh
          3. add the content of <TOP>/startup/crontab/crontab.entry to your crontab:
            (just a help xclip: puts the content to the clipboard)
            cat <TOP>/startup/crontab/start_procServ_EPICS_apfel.sh | xclip -sel clip && crontab -e
          4. reboot or start IOC via procServ only.
