Re: Feedback to Guage on Denon - Now Working

I have not yet finished the project :-(
(Thinking of moving to onkyo as zones not working on this denon)

Anyway here is how I was able to get feedback working.

Here are the images that I use: http://vandermehrn.com/lc/feedback/

Everything lies in the REGEX.
Things to note.

You do not need to escape the "\" in "\x0D" EXCEPT when testing your
regex in the regex tester. (no quotes in regex)

For example to get feedback on the guage for volume, I send the denon;

MVUP\x0D

The denon responds with

MV50\x0D . . . MV51\x0D. . .MV52\x0D. . .MV53\x0D and so on as long as
it gets a new "volume up" command it will respond with the new change in
value.

A regex to capture this would be ^MV(\d*)\x0D$ (Thanks Jarrod. . . see
below)
The first and last characters of that regex are for matching the
responses that have that exact format. (in case there are other
responses) in the data stream.
What is important is that the values in the brackets are captured.

We will now need to assosciate these captured values\events to a guage.
To do this we need to give a guage and the captured event the same join
numbers.
In this case 222.

We also need to specify the minimum and maximum values for the guage so
it is scaled correctly. (in the feedback manager)
For this Denon the volume response range goes from 0 - 98.

I learn as I go so anyone please add what you might think I missed out.
