EPICS layer for NDS3

This project contains the EPICS layer for the NDS3 framework. It has three important directories, ndsSup, demo and demo2.

• ndsSup contains the NDS EPICS layer software library nds3epics.
• demo contains the first demonstration IOC which demostrates that drivers can be loaded at runtime before IOC init instead of being linked against. The drivers used in the demos are in the NDS3 repository.
• demo2 contains the second demonstration IOC which is using Gnu Linker to load the driver instead.

In order to compile and use this project NDS3 has to be installed.

Manual Installation

Prerequisites

• EPICS Base
• Asyn
• NDS3

Build and run

• Update the configure/RELEASE file with the correct location for EPICS base, Asyn and NDS3.
• Run make from the project root folder.
• Run IOC with cd iocBoot/iocdemo && ../../bin/linux-x86_64/demo st.cmd.

More detailed instructions can be found in run_demo.md.

Usage

Example of usage:

[root@8b8481acd71f iocdemo]# ../../bin/linux-x86_64/demo st.cmd
#!../../bin/linux-x86_64/demo
## You may have to change demo to something else
## everywhere it appears in this file
