Hi Andrew,
I have gratingTCP working fairly well - I can change parameters from the
remote computer with commands like 'tf = const(1.0)'. But now I want to
use the 'go' command for precise timing control, and it's not working the
way I expected. Will you show me an example script that correctly uses
'go'? For example, what is wrong with:
go_duration = const((3.,'seconds'))
contrast = const(0.9, 0.1)
go = const(1)
to produce a 3s contrast step? This causes the screen to flicker to a low
contrast every 3 seconds. I can improve this by changing:
go = const(1,0)
which performs the contrast step correctly, but only once. When I reissue
the same command, it doesn't work again. So I have a go that goes
repeatedly, or one that works only once. I want it to execute whenever I
send the command.
Thanks for your help!
Jamie
