Thanks!
And the callback function is ok or do I have to callback also the 'checkTrigger' function?
##############################
#Create the signal object
sig = vizact.signal(Trigg > 0)
#Create an action to wait on the signal
waitsig = vizact.waitsignal(sig)
def ExtTrigg(waitsig)
### add SOUND
song = viz.add('Beethoven.wma')
song.loop(viz.OFF)
###+++++++++++++++++++++++++++
def checkTrigger():
trigg = d.eAnalogIn(0)
if trigg > 0:
ExtTrigg()
vizact.onupdate(0, checkTrigger)
viz.callback(viz.ACTION_BEGIN_EVENT,ExtTrigg)
