NTP - GPS EPICS Server and OPI Interfaces

Author:

Gustavo CIOTTO PINTON

Description

This project contains two possible EPICS PV server implementations and some opi interfaces capable of reading the provided PVs.

The python implementation can be found in PCASpy folder and it is based on the PCASpy module. The second implementation consists of a bridge between NTPD and GPSD daemons and Stream IOC. It essentially uses an UNIX socket to exchange data between applications and provides BSMP entities.

Requirements

1. GPS-PV-Server.py requires pcaspy, ntplib and libgps modules.
2. ntpd_ioc.c requires NTPD source files and gpsd_ioc.c requires libgps-dev package. libbsmp is also required.
3. A Control System Studio instance is required to open and run the interfaces.

Running

1. python PV server: edit GPS-PV-Server.py with server's correct IP address (_address) and variable name prefix (_prefix).
2. Using with Stream IOC: run ./ioc_main and start Stream IOC afterwards.
3. OPI interfaces: open CSS and run Host-selection.opi. You will need to include or remove buttons and macros in Host-selection.opi, depending on how many servers are available.
