simple rotary encoder for feed override?

Hi,
I'm trying to setup a rotary encoder to control feed override. not a mpg, just a cheap encoder like this:

I've been going through the HAL docs and looking at examples, and I still can't figure it out. So far this HAL stuff just hasn't 'clicked' with me yet. Seems the more examples i find, the more confused I get.

I've got the a-out and b-out pins hooked up to pins 13 and 15 on my breakout board, and ground to ground (i'm not using the push-click switch).
So far, this is what I have in my custom.hal:
What it does with this is each turn/click either increases or decreases the feed override setting, and then immediately bounces back to it's original value.
I feel like it's one simple thing I'm missing somewhere in my hal, but can't figure it out.
...feeling rather hal-incompetent at the moment.

you don't want to connect to halui.feed-override.increase or decrease.

you want to connect encoder.0. counts to halui.feed-override.counts
you might have to scale the counts too.

parport pins control the encoder commponent - it counts the changes.
The encoder component sends the count number to the halui.feed-overide component.
the halui.feed-override component sends messages to linuxcnc based on the counts.

linuxcnc.org/docs/2.7/html/gui/halui.html
linuxcnc.org/docs/2.7/html/hal/rtcomps.html#_encoder

Hope that helps.

Thank you!!!
I knew I was missing something simple, just not sure I ever would have made that connection on my own.

Here's the code now, in case this helps any other hal-impaired folks like myself
