Great work Gavin! Do I need to register the client or anything like that? Or do I simply create the button in NR, and NR knows to ask Girder for the appropriate feedback?

Thanks,
Zak

NetRemote will connect to Gireder automatically (and Girder will open a connection back). Registration, as it was, has gone - the TCP sessions are persistent. All you need to do is load the plugins, and call the LUA code. NetRemote tells Girder where it is - no hard coding.

So far all nasty situations (confused programs) have been resolved by restarting NetRemote - Girder resets are not necessary any more.

Once I get LDJ done - I really need to get a full feedback ZoomPlayer CCF out.

Great job Gavin...I just finished integrating the new feedback into my multizone setup and it works great. Both of my clients are registering and feedback is quick to these units (one is a PC and the other is an Ipaq).

Just thought I would let you know...

Kevin - good to hear it's working for you. I was worried that getting all the bits installed could be a bit traumatic.

I would be interested how well it behaves if one client goes away (e.g. powered off).

Hey Gavin,

Getting the parts all installed and interfacing was a bit of a challenge but not to bad - took a little bit to understand how to script the feedback to the buttons but makes sense now.

Here is a quick note on some testing I just did...something a bit odd is happening - but it is late at home right now (just about 1:00am) so it could be me :wink: but here is what is happening.

When I have both clients connected and then I turn off the Ipaq the netremote session that is on the PC gets corrupted - screen basically goes blank. I have to turn that one off as well, I can turn it right back on and it is fine - I look in the logger and the only things that I can see are that the Ipaq disconnected - there is no other error that I see. Once I shut down the PC session it logs that as well but no obvious errors.

The odd part of this is that it only happens if I shut off the Ipaq...if I shut down the PC session the Ipaq keeps on ticking with no problems?? Very Odd.

I will check this some more tomorrow night after work to see if it is something that I am doing....

Hmm - It may be the timeouts on the LUA side. Depending on how a system shutsdown it may have different effects on the TCP sessions. - Gavin

Hey guys,

damn, this looks trés cool.. BUT, I'm a dummie when it comes to LUA, so I would like some more help on how to apply all this into Girder and Netremote. Help would be dearly appreciated!

Cheers,
Jens

Ps. if you want to, email me at jens.samuelsson@tre.se

[brockgr]

Yep Jens - a "howto" on Feedback has been on my promise list for a while. It's just that feedback has been evolving faster than I can keep up.

I'm thinking of a do-it-yourself ZoomPlayer with feedback for an example.

So when will the "You have allready done it for me ZoomPlayer" come? :wink:
