Welcome to Goetz Pfeiffer’s Project Site
This is a list of open source projects mostly related to my work at the Helmholtz-Zentrum Berlin.
For some projects, I am the only developer, for others I have made contributions.
A third category of projects have no contributions by me but are republished here since they are very old and hard to find anywhere else.
All projects are have some kind of open source license, the copyright holder is described in the project.
Databases
Projects that act as a database.
YAML-StructuredData: Software to manage, organize, storing and type-check your data in the YAML format.
Software development
These are tools that in general help software development:
hg-diff: hg-diff is a program to browse and compare mercurial revisions.
hgen: A tool to generate C header files from special comments in C source files, written in perl.
pyexpander: A turing complete macro processor with python syntax
rsync-dist: This manages the distribution of files, programs and binary data to a server. All old versions are kept and active versions are selected with symbolic links.
Field Bus I/O
EPICS Projects
EPICS is a set of software tools and applications which provide a software infrastructure for use in building distributed control systems to operate devices such as Particle Accelerators, Large Experiments and major Telescopes.
The following list shows projects that are used for EPICS:
DM2K: A display manager for EPICS. Note that this is legacy code. It is not recommended that you use this display manager for new developments.
EDM: A display manager for EPICS. Check out with
git clone -b HZB https://github.com/goetzpf/edm.git, then follow instructions in file “README.install” under heading “HZB branch”.Pezca: A Perl interface to channel access, the EPICS network protocol.
sumo: The support module manager sumo is a program to build consistent sets of EPICS support modules and use them in EPICS applications.
EPICS Device Supports
Projects that implement interfaces to certain hardware for EPICS.
almLib: An EPICS high resolution timer and alarm clock library for Linux and RTEMS.
apps_generictemplate: An EPICS support module to create EPICS template and panel files for applications at the Helmholtz-Zentrum Berlin
apps_iocwatch: EPICS IOC statistics support for Linux PCs and for the mvme162, mvme2100 and mvme5500 CPUs running with RTEMS.
apps_powersupplies: An EPICS support module to control power supplies at the Helmholtz-Zentrum Berlin
bspdep-timer: A timer device support needed by almLib. This is a high resolution timer for Linux PCs and the mvme2100 or mvme5500 VME bus cpu card with the RTEMS operating system.
misc_dbc: An EPICS device support that provides some assertion macros, nothing else.
MultiCAN: An EPICS device support for the CAN Bus. Supports the operating systems RTEMS and Linux. For Linux support see also socan.
EPICS sequencer: The Sequencer implements a language for programming state machines with the EPICS framework.
soft_devhwclient: A special record for MultiCAN.
RTEMS support
The operating systems RTEMS is an open source real time operating system.
At the Helmholtz-Zentrum Berlin RTEMS is used on VME Bus systems in the control system.
The following list shows projects that help with RTEMS software development:
rtems-from-scratch: This helps to build the RTEMS cross compiler and other development tools. Very old RTEMS versions like version 4.9 are abandoned on the RTEMS project and the cross development tools can no longer be built directly. This project allows to create the cross development tools for RTEMS 4.9, 4.10, 4.11 and 5.1.
rtems-build-tool: This helps to build a RTEMS boot image for VME Bus CPUs at the Helmholtz-Zentrum Berlin. For RTEMS 4.9 it also compiles cexp and GeSys in the boot image which implement an interactive shell and support for dynamic loading of modules.
RTEMS sources
These are used by rtems-build-tool which downloads them for you. These projects are here just for completeness.
A modified RTEMS kernel: This is the original RTEMS kernel repository with some extra branches (4.9.6-HZB and 4.10.2-HZB) that contain additional patches developed at the Helmholtz-Zentrum Berlin. This repository is automatically fetched when you use rtems-build-tool, so you usually don’t have to download this yourself.
RTEMS cexpsh: A shell with support for dynamic module loading for RTEMS 4.9. This repository is automatically fetched when you use rtems-build-tool, so you usually don’t have to download this yourself.
RTEMS libbspext: Extended board support for RTEMS 4.9 on mvme2100 VME bus cpus. This repository is automatically fetched when you use rtems-build-tool, so you usually don’t have to download this yourself.
RTEMS bootlib: Boot parameter support for RTEMS on VME Bus CPUs. This repository is automatically fetched when you use rtems-build-tool, so you usually don’t have to download this yourself.
RTEMS GeSys: A package that together with RTEMS cexpsh creates a bootable image for RTEMS on VME bus cpus for RTEMS version 4.9. This repository is automatically fetched when you use rtems-build-tool, so you usually don’t have to download this yourself.
Undulator control
This is software used to control Undulators at the BESSY synchrotron facility at the Helmholtz-Zentrum Berlin.
IDCP: The insertion device control program. This program runs on Linux and RTEMS.
IDCP Documentation: This is comprehensive documentation of Undulator control at BESSY and related programs.
id-db: The parameter database for IDCP, the insertion device control program.
uniserv, The program that runs on the UniDrive motor control device that is used for the BESSY Undulators.
Miscellaneous
Projects that don’t fit another category.
bash-dirstack: Implements a flexible directory stack for the bash shell.
bii_scripts: A collection of scripts for generic software development and for working with EPICS.
