Re: Re: xPL newbie (still!) needs help with xPL_HomeVision (detecting
variable chang
Hi Frank,
I'm pretty sure my xPL/HV setup is fine - everything works, but the
performance of the actual HV controller dramatically decreases (in
some circumstances).
The problem is simply due to the amount of work HV has to do handling
DDE requests when a variable (or flag) gets updated so frequently. My
understanding is that HV simply says "a variable has changed" but
doesn't say which one. So, in order to detect which variables have
changed, xPL_HomeVision has to request ALL the variable values from HV
and compare them to the previous values. Doing this every 0.4 seconds
is just not feasible for HV and controller slows considerably, such
that there is a noticable delay in responding to input ports changing
etc.
I think there could be a nice way to tackle this but it would require
a change to xPL_HomeVision - I'll drop Steve a mail offlist and see if
he thinks it's worth it.
To test, try updating one of the variables you "watch" in a
periodic
event that runs every loop and then have a play with something
connected to HV input ports, say FirM.
What I observed was that the LED which used to change colour every 0.4
seconds, now took ~3 seconds to change purely because HV was busy
handling DDE requests.
Let me know how it goes... ;o)
Thanks,
Andy.
