ESS Site-specific EPICS module : ecmcPlugin_FFT
A shared library with FFT functionalities loadable into ecmc:
https://github.com/epics-modules/ecmc (or local ess fork https://github.com/icshwi/ecmc).
Configuration is made through ecmccfg:
https://github.com/paulscherrerinstitute/ecmccfg (ot local ess fork https://github.com/icshwi/ecmccfg)
# Introduction
The main functionality of this plugin is to make FFT analysis of ecmc data. Most data in ecmc is accessible:
1. EtherCAT data (ec0.s1.AI_1)
2. Motion data (ax1.actpos)
3. PLC data (plcs.plc0.static.testvalue)
1. EtherCAT data ("ec0.s1.AI_1" or "ec0.s2.mm.CH1_ARRAY")
2. Motion data ("ax1.actpos")
3. PLC data ("plcs.plc0.static.testvalue")
Precautions have been taken in order to disturb ecmc real time thread as little as possible:
1. All CPU intensive calculations are handled in a low prio work thread (not ecmc thread).
