NDS v3

Introduction

NDS (Nominal Device Support) is a library that allows to write device supports for a variety of control systems (CS) by hiding the details of the chosen CS and focusing on device functionalities.

NDS provides the following features:

• organizes your device in a tree-like structure, containing one or more devices, channels, attributes (PVs), state machine, etc.
• provides the data pull mode (passive scanning on EPICS, polling on Tango) and the push mode (Interrupt on EPICS, push on Tango)
• your code uses standard C++ types and Unix EPOCH timing to communicate with the library
• on EPICS there is no need to supply separate db files (but you still can if you want)
• supplies an hierarchical state machine
• supplies a specialized data acquisition module
• guaranteed binary compatibility between minor versions allow to easily upgrade existing installations without recompiling the device support

Documentation

• Online Reference
• Build doxygen reference with make doc. Requires doxygen and latex. The generated documentation is then found at doc/api/html/index.html and doc/api/hlatex/refman.pdf.

Developer Dependencies

cmake 2.8.2+ required to run unit tests. Included in RHEL 6.6, Debian Wheezy, Ubuntu Trusty.

GCC 4.9+ is recommended because of GCC 57869.
