Add physical controls for Keg operations without management PC access #2

Open SvenRoederer opened 8 years ago

SvenRoederer commented 8 years ago

Think it would be nice to have some buttons to change the keg without the need of a PC

@MicDiFebo is this a feature you referenced by "Kür"?

MicDiFebo commented 5 years ago

Ack, I was thinking about having a reminiscence to the classical BC, where we had 4 buttons for basic operations directly on the device. That were Up, Down, Enter, Escape/Back. Thats all we need.

SvenRoederer commented 5 years ago

Do we have such 4-way control? What about an encoder (turn left, turn right, press button)?

What functions do we want to control?

MicDiFebo commented 5 years ago

Encoder sounds good - a pushwheel, push = Enter for example. Needs one more back-button. I have some in my Geraffel-Kiste....:-)

SvenRoederer commented 5 years ago

We can also use a "back" menuitem or a "longpress" return feature.

SvenRoederer commented 5 years ago

But I'm really unsure, if we can reliable decode the Encoder and it's operation and in parallel doing reliable counting of pulses (see issue #5).

MicDiFebo commented 5 years ago

We should do it like in a car where you also (normally) cannot edit the setup-parameters while driving. Meaning that local control elements should be blocked while drafting beer.

As an potential alternative to the Encoder I got a Adafruit 12-channel touch-sensor (https://www.adafruit.com/product/1982)
