[visionegg] Re: graingTCP

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
