# uopi test SoftIOC startup script
|
|
#
|
|
# Prerequisites:
|
|
# • EPICS Base 3.15+ (for RNDM calc function)
|
|
# • 'softIoc' binary in PATH (usually $EPICS_BASE/bin/$EPICS_HOST_ARCH/)
|
|
# • Optional: caput (from EPICS tools) to pre-fill UOPI:WAVEFORM
|
|
#
|
|
# Usage:
|
|
# cd workspace/softioc
|
|
# ./st.cmd
|
|
#
|
|
# Or directly (no waveform pre-fill):
|
|
# softIoc -s -d workspace/softioc/uopi_test.db
