Hi Michael,

For completeness, something like this would be a "more minimal" example:

import time

import numpy
import epics

needs_calc = False

def onButtonPush(pvname, value, **kws):
needs_calc = (value = 1)

button_pv = epics.PV('Button:bo', callback=onButtonPush)

image_pv = epics.PV('AreaDetector:image1:ArrayData')

while True:
time.sleep(0.025)
if needs_calc:
needs_calc = False
button_pv.put(0)
print("Do real calculation here ", numpy.sum(image_pv.get())

--Matt
