Greenfield Engineering Corporation

Welcome to Greenfield Engineering a small business in Southern Maryland.  Greenfield was incorporated in July 2002.  We build embedded realtime systems.  We specialize in VxWorks VME systems and Graphical User Interfaces running in a realtime environment.

Background :: Greenfield Engineering is a small business based in rural southern Maryland.  Our primary business is Software Engineering and Systems Engineering for complex realtime systems of the US Navy.  Systems include realtime command and control of remote RF equipment and Identify Friend or Foe Host Processing.  Specialization in complete requirement, design test and field of software and software systems.

Realtime :: Greenfield Engineering has expertise in development of realtime systems utilizing the vxWorks operating system.  The development platform is typically a SUN Sparc workstation.  These realtime systems are built by utilizing a cross compiler development environment that is connecter to the host via Ethernet.  This allow for high speed compile and debugging while keeping the target environment scalable.

Graphical User Interface :: Realtime software systems are expanding capabilities by adding graphical user interfaces and touch screen capability.  Greenfield Engineering developed a GUI based on X11 that runs as a task in the realtime environment.  This GUI utilizes the Motif and XLib libraries to provide an open systems approach to the software and its maintenance.  Since this system is small, it utilizes a front panel touch screen instead of the typical mouse operation.  This saves space and makes the GUI intuitive.

Linux :: Linux graphical user interfaces are typically built using the GNOME/GTK+ libraries.  This implementation is an easy step from the Motif library set and is based on X11.  Greenfield Engineering is building a Linux software interface to control various equipment over the Ethernet interface.  Linux is cost effective considering the open source software.
