External Trigger via LabJack

[ursi]

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)
##############################

The line of code

vizact.onupdate(0, checkTrigger)

already registers the checkTrigger function and that will be called every frame. Have you tried running that on it's own without the code you added?
